A devDuck update!
First off, thank you to everyone who has purchased a devDuck (or a bunch!) and thanks to all who have given us feedback. @trogus and I are thrilled at the incredible response these ducks have gotten. If you haven’t seen them yet, you can check them out at https://devDucks.com or the devRant Swag Shop (https://swag.devrant.io).
We are trying to process all of the orders as quickly as possible and our goal is to have all current orders out by the middle of this coming week. Many orders have already shipped, but if yours hasn’t, rest assured it will very soon!
If you ordered a Java devDuck or cape, your order might be delayed a bit until the middle of this coming week because Java seems to be a heavily-demanded cape and we needed to get the material shipped in to make more of that, specifically.
So far we’ve gotten some awesome feedback from the community. A short list of possible future additions based on what’s been requested: Go devDuck, Kotlin devDuck, Perl devDuck, Android devDuck, and possibly some devDuck accessories like little hats, sunglasses, headphones, etc. If you have any other ideas just let us know:)
Lastly, please know that even with the launch of devDucks, we remain extremely committed to the devRant product and we have some very exciting big devRant features coming very soon.
Thanks again everyone!28
A newly met person, who sat next to me in class: I heard you do machine learning... I develop android apps too
Me: Oh nice, what do you do, Java or Kotlin?
Him: I do Android studio

I'm 20, and I consider myself to be as junior as they come. I only started programming seriously in June 2016,and since then, I've been doing mainly Android Work, and making my own servers and backends(using AWS/Firebase nd stuff).
For the first time in life, I was approached by a recruiter for a company on linkedIn. They "stumbled upon" my Github profile and wanted to see if I was interested in an internship opportunity. This company is an early stage start up, by that I mean a dude with an idea calling himself the CEO and a guy who "runs a tech blog" and only knows college level C programming (explaination follows).
So they want me to make the app for their startup. and for that, I ws first asked to solve a couple problems to prove my competence and a "technical interview" followed.
They gave me 3 questions, all textbook, GCD of 2 numbers, binary search and Adding an element to the linked List, code to be written on a piece of paper. As the position was that of an Android Developer, I assumed that Java should be the language of choice. Assumed because when I asked, the 'tech blogger' said, yeah whatever.
But wait, that ain't all, as soon as I was done, Mr. Blogger threw a fit, saying I shouldn't assume and that I must write it in C. I kept my cool (I'm not the most patient person), and wrote the whole thing in C.
He read it, and asked me what I've written and then told me how wrong I was to write 2 extra lines instead of recursion for GCD. I explained that with numbers large enough, we run the risk of getting a stackoverflow and it's best to apply non recursive solution if possible. He just heard stackoverflow and accused me of cheating. I should have left right then, but I don't know why, I apologized and again, in detail explained what was happening to this fucktard. Once this was done, He asked me how, if I had to, I'd use this exact code in my Android App. I told him that Id rather write this in Java/Kotlin since those are the languages native to Android apps. I also said that I'd export these as a Library and use JNI for the task. (I don't actually know how, I figured I can study if I have to).
Here's his reply, "WTF! We don't want to make the app in Java, we will use C (Yeh, not C++, C). and Don't use these fancy TOOLS like JNI or Kotlin in front of me, make a proper application."
By this I was clear that this guy is not fit to be technical lead and that I should leave. I said, "Sir, I don't know how, if even possible, can we make an Android App purely in C. I am sorry, but this job is not for me".
I got up and was about to leave the room, when we said, "Yeah okay, I was just testing you".
Yeah right, the guy's face looked like a howling monkey when I said Library for C, and It has been easier for me to explain code to my 10 year old cousin that this dumbfuck.
He then proceeded to ask me about my availability, and I said that I can at max to 15-20 hours a week since my college schedule is pretty tight. I asked me to get him a prototype in 2 months and also offered me a full time job after I graduate. (That'd be 2 years from now). I said thank you for the offer, but I am still not sure of I am the right person for this job.
He then said, "Oh you will be when I tell you your monthly stipend."
I stopped for a second, because, money.
And then he proceeded to say 2 words which made me walk out without saying a single word.
I live in India, 1000 INR translates to roughly $15. I made 25 times that by doing nothing more than add a web view to an activity and render a company's responsive website in it so it looks like an app.
If this wasn't enough, the recruiter later had the audacity to blame me for it and tell me how lucky I am to even get an offer "so good".
Fuck inexperienced assholes trying shit they don't understand and thinking that the other guy is shitsworth.10
At a busy restaurant.
Person 1: oh my God this man here is having a heart attack. Is there a doctor here?
Person 2: here's ten reasons why Kotlin is better than Java for Android development5
Going back to Java after being writing code in Kotlin for a while feels like going back with your crazy, over reacting ex.3
*Adds new dependency*
Me: *Pray while syncing*
*Gradle project sync in progress*
*Gradle build finished in 9s 211ms*
Me: Thank you, Lord5
I just started learning Kotlin for a week or two and suddenly Google announced Kotlin will be officially supported for Android development.
Converting old Android projects to kotlin feels soo damn good!
All that Java garbage is going into the t r a s h, boy8
Friend: Hey, so what do you do?
Me: I build backend systems and apis. I work with java/mongodb. I dable into some elixir and kotlin on my free time.
Friend: Cool, can you build me an Android app?11
Yahoo, Kotlin is the first class language for android. So no more fucking Java codes. No more 100 lines for basic configurations. No more null pointer exceptions.
Only beautiful code and fun.15
Android really gets on my goat. They are moving things so far that they are actually doing more damage than good.
Upgrade my build tools to v25? sure! Now all my BLE code is borked, thanks for nothing.
Go to the documentation? Lol, that's deprecated fool!
At least now it can all fail to function in Kotlin, a wrapper for Java 6. Instead of keeping your tools up to date you just create another layer of obfuscation. Well done, so proud.3
Frustrated, tired and a bit lost.
I'm a "Senior PHP Backend Dev", which includes not the greatest tech stack nor the best job title, but it pays fine, and the company is awesome to work for.
I suck at writing features, but I'm great at bitching, and I easily put complex abstract concepts into usable models. So I'm also QA, tester, tech lead, database architect, whatever.
That makes writing PHP less annoying, because I create the rules, and whip devs around when they forget a return type definition or forget to handle an edge case. But I don't write a lot of code anymore, I mostly read (bad) code.
Lately I REALLY feel like doing something else... problem is that I know JS/ES6, but really dislike React/Vue and the whole crappy modern frontend toolchainchootrain of babelifyingwebpackingyarnballs. I know Python/Tensorflow/etc, but don't feel like I want to go into data science or AI. And then I'm awesome at the shit no one uses, like Haskell, Go and Rust (and worse).
I got a job offer which combines a very interesting PHP codebase with a Java infrastructure, where I could learn a lot... and I'm kind of tempted.
Problem is, everyone always shits on Java. I always made a bit of fun of Java myself. Don't even know exactly why, probably some really cruel instinct which causes kids to bully the least popular kid.
I know the basics, I've written the hello world, and a small backend app for a personal project. I know how strict and verbose it can be. I love the strictness in Haskell and Rust.... but those are both also quite terse.
Should I become a Java dev? I'm not talking about Android SDK, but an insane enterprise codebase at a life sciences corporation.
To the pro Java devs: What are the best and worst things about your job, about the weekly processes, about the toolchains? Have you ever considered other languages? Do you unconditionally love and believe in Java, or do you believe Swift, Kotlin, Scala or whatever will eventually make it completely obsolete?
Will Java hasten my decline into the cynical neckbeard I was always destined to be?
There are a lot more fun langauges, but looking at realistic demand and career value...20
sooooooooo for my current graduate class we were to use the MVC pattern to build an IOS application(they preferred it if we did an IOS application) or if you didn't have an Apple computer: an Android application.
The thing is, they specified to use Java, while in their lectures and demos they made a lot of points for other technologies, hybrid technologies, such as React Cordova, all that shit, they even mentioned React Native and more. But not one single mention of Kotlin. Last time I tried my hand at Android development was way before Kotlin, it was actually my first major development job: Mobile development, for which we used Obj C on the IOS part and well, Java on the Android part.
As some of you might now, I rarely have something bad to say about a tech stack(except for VBA which I despise, but I digress) and I love and use Java at work. But the Android API has always seem unnecessarily complex for my taste, because of that, when I was working as a mobile development I dreaded every single minute in which I had to code for Android, Google had a great way to make people despise Java through their Android API. I am not saying it is shit, I am not saying it is bad, I just-dont-like-it.
Kotlin, proves a superior choice in my humble opinion for Android development, and because the language is for retards, it was fairly easy for me to pick it up in about 2 hours. I was already redesigning some of my largest Spring applications using half the code and implemented about 80% of the application's functionality in less than 3 hours(login, fragment manipulation, permissions, bla bla) and by that time I started to wonder if the app built on Kotlin would be ok. And why not? If they specifically mentioned and demonstrated examples using Swift, then surely Kotlin would be fine no? Between Kotlin and Java it is easy to see that kotlin is more similar to Swift than Java. So I sent an email. Their response: "I am sorry, but we would much rather you stick with the official implementations for Android, which in this case is Java for the development of the application"
I was like 0.o wat? So I replied back sending links and documentation where Google touted Kotlin as the new and preferred way to develop Android applications, not as a second class citizen of the platform, but as THE preferred stack. Same response.
Eventually one of the instructors reflected long enough on it to say that it was fine if I developed the application in Kotlin, but they advised me that since they already had grading criteria for the Java program I had to redo it in Java. It did not took me long really, once I was finished with the Kotlin application I basically rewrote only a couple of things into Java.
The end result? I think that for Android I still greatly prefer Kotlin. Even though I am not the biggest fan of Kotlin for anything else, or as my preferred language in the JVM.
I just.......wish....they would have said something along the lines of: "Nah fam please rewrite that shit for Java since we don't have grading criterias in place for Kotlin, sorry bruh, 10/10 gg tho" instead of them getting into an email battle with me concerning Kotlin being or not being the language to use in Android. It made me feel that they effectively had no clue what they were talking about and as such not really capable of taking care of students on a graduate level program.
Made me feel dirty.12
All the languages have a basic objective in mind that shapes both the language and it's community:
for c/c++ was low level hardware access and performance, for Java OOP and learning; Kotlin was mostly made to make dev life easier and tries to anticipate what you want to do instead of forcing his patterns and tries to help you instead of punishing errors.
As a dev at least i feel a little more cared about and less left alone (especially in the ugly world of Java for Android)14
Porting Java Code to Kotlin manually, just to get a better understanding of the language. Best thing so far, NO more Assertive Exception Handling.
Damnit Java, I know it for a fact that the damned thing won't throw an exception! There's Careful and Paranoid. KNOW THE DIFFERENCE5
I'm a backend (Java, Kotlin) developer and I mainly design & develop services and Android apps which consume these services.
My team in my current organization (I've been working here since past 2 years) just got merged with another team.
And now the new boss wants me to fix some fuck ups in their project which is written in C#, with some WCF and other stuff.
As this stuff is completely new for me, I asked for some time to get familiar with the environment. But the answer was a big NO.
As a result, "I've started looking out for a new job"
Fuckin management screws up everything!4

Truth: You will regret not using Kotlin as soon as possible. Don't deprive yourself of pleasant development and productivity boost.5
Got back into android development recently and while everything was pretty flawless ( I managed to get the basic concepts implemented in a day) something wasn't right.
For some reason I was not happy with the code i wrote, although I took examples from google and tried to adapt their code style. It looked aweful. I hated my code.
But the code itself wasn't the core of the problem. I could easily add new features and replace components with new implementations without breaking the app. All those "good code quality" identifiers were there.
Turn out the problem is Java. Or to be more specific: Java 1.6
Every listener which only calls a single function once a worker has finished needs 6 lines of code. If you implement the inferface in the class it gets messy once there are multiple workers and you have a generic interface. And there are no lambdas!
So I made the switch to Kotlin.
The app was converted to kotlin in 30 Minutes. Android studio can convert the classes automatically and very little manual work is needed afterwards.
After that I spent 2 hours replacing the old java concepts with Kotlin concepts: lamdas, non-nullable types, getters and setters in kotlin style (which in this case is c# style) and some other great thing.
The code is good looking now. I like it. I like kotlin as it has a lot of cool things.
Android dev is fun again!2
hi guys, i'm django developer and i wanna learn android.
should i choose kotlin over java?
how is job vacancies?22
Kotlin support on Android:
i never liked Java, not because of the language but for the usual bad design implementations and Android is one of those.
Then Kotlin arrived, it looked very promising but it's when i looked at Coroutines that it simply blew my mind:
you just have to write your code and the Kotlin's compliler "magic" will do most of the boring/complex stuff for you and it's even great performance wise!
I even refactored inter-process calls to simple sync functions with few like of code and for a non-android developer like me it's just love at first sight!2
I laughed waaay to hard at this. Anyone using kotlin? The language seems really nice, i currently develop with React Native if I can avoid java on android (too much to do too little) and was thinking about kotlin.2
Is kotlin is worth trying? I'm a android developer and I used Java for creating my application. Maybe you can give my some advise.9
More like a sub company/department inside a company: Android.
I still use it as my main driver, but every time I try to get back into development with it(did it professionally for 2 years nearing on 3 and was a lead Android dev, mind you not necessarily by merit....) I end up hating everything about it.
The tooling is meh, the API is hideous and even with the addition of Kotlin, which I do find a nicer language over Java I still dislike it. The ammount of shit needed to make something as simple as store data, manage fragments, integrate with the NDK, make JSON API calls or even shake motions is just ludicrous and counter intuitive. I can see why people would hate Java based on Android, a language that I generally love and defend.
I firmly believe that people extend frameworks or tooling for 2 reasons only:
1 the stack is so awesome that you just want to create packages and libraries to extend the functionality of a powerful environment, like gems for Ruby, python packages, Node packages, php composer, nuget etc
2 the stack is so fucking hideous that people need to fix shit: the entire android square utility framework, butterknife, flutter, react native, codenameone, etc etc
The case with Android is the second. I have not met a professional Android developer that completely likes everything about Android, but will seldom find people that HATE other frameworks or environments.
Android it is for me. Still my daily driver and I love every Android phone I have ever owned. It just makes me feel lots of more compassion for fellow Android devs.4
Just switched to Kotlin.. For the first like 10 minutes I was like "What is this shit?!" and then I found Java to Kotlin converter and docs. Yay! Looks like it´s not gonna be that hard to do some apps in it.. Hopefully4
Goodbye Java I will not miss you at all! I swear ...
I do like it when making web services (especially that I can use Java8) but for Android you have been a torture. Hello sweet Kotlin! I shall embrace you and treat you like my newly born baby!!
Working on a new project where I need to talk to a web service (also made by me).
Started writing in Java, all is cool and unit tests pass.
Downloaded Android Studio 3 Beta 1 and converted my Java code to Kotlin, That AsyncTask did not look nice in kotlin, converted it to async & await feature and I must admit lots of code removed, no more need to create a new fucking AsyncTask every time the app sneezes for data!
I feel like I'm working with C# but with difference in syntax.
My life is now complete :)8
- finish the app for my school
- FUCKING finish the google scholarship before time ends ._.
- learn git
- build a home fileserver, like a own cloud, which can be accesed even further away (has any one some tips on how to do it? ^^)
- attach a gps tracker to my moped, which I can then see on a mobile app (because I don't want it to be stolen...)
- rebuild my homevillages website
- learn python
- replace my android Java with kotlin
- apply to an internship for a software design company
- more and more and more
Hope you guys will have a nice and PRODUCTIVE 2018! :^)10
Tried flutter for the first time in life, for 2 days, java based Android dev here.
I have some.... thoughts...
Flutter does not feel extremely new to me. It is very much relatable if you have ever tried basic the spring/ other java based gui framework. It is trying to achieve the goods from multiple worlds,its so far good, but mann its playing on thin ice.
Flutter : Yo boy embrace me. I am the beauty. checkout my hot reload.
Me :❤️❤️😍 (But wait. your first execution is wayy longer than a simple android studio build. And AS would generally take smaller time after every rebuild. And you are going to take the same long time as first build, if app gets closed or my usb gets accidentally removed. So I see what you did there ;))
Flutter: Ha. Checkout my function passing as parameter. ever thought your puny java going to give you that?
Me :you got me ,❤️. (Although this style is not so uncommon with web devs)
Flutter: everything is a widget, everything is stateful or stateless, Single Streams FTW!
Flutter:You kotlin devs are gonna love me, i got Small, concise code
Me: Now wait, This is a thin ice for me, okay? I hated when kotlin replaced everything with symbols & lamdas for a confusing but small code, So be careful,even though your code is still good.
Flutter : Control every pixel , dear! No more xmls!
Me : Yes, what is with that? are we accidentally going in the past?
Java desktop apps, spring framework used to build whole layouts with programming language. The day i stepped into Android, it was xml for ui and java/kotlin for code. was that a bad decision or is this one?
Anyways i liked my stuff seperated, but that's just me.
Flutter : Ugh so much whining. Are you going to work with me or not?
Me : Yes mam! ❤️4
had to create a rather large CLI based application in Java as a graduate level assignment.
Doing shit like this makes me appreciate Node/Python/literally fucking anything else much more for this shit in which storing and retrieving JSON does not have to be that much of a fucking hassle WITHOUT using external libraries(they want it all made by hand)
I love Java, don't get me wrong, but I would rather use it for only a couple of things. I stopped working as a Mobile dev precisely because of Android being shit for Java. No, Kotlin does not fix it, its not the language that is my problem, its the fucking general architecture of the Android API that pisses me off.
And no, I do not care if you like it, like 1 fucking bit. I am not saying that the architecture is shit, I am saying that I did not like it.
Sigh.......oh well. Almost done with the assignment, but still.7
I don't get it.
I tried Kotlin on Android just for fun, and it doesn't support binary data handling, not even unsigned types until the newest version. Java suffers from the same disease.
How does one parse and process binary data streams on such a high end system? Not everything is highlevel XML or JSON today.
And it's not only an Android issue.
Python has some support for binary data, and it's powerful, but not comfortable.
I tried Ruby, Groovy, TCL, Perl and Lua, and only Lua let's you access data directly without unnecessary overhead.
C# is also akward when it comes to data types less than the processer register width.
How hard can it be to access and manipulate data in its natural and purest form?
Why do the so called modern programming language ignore this simple aspect that is needed on an everyday basis?11
Yes || No || Donno
Thinking about giving it a small touch but wanted to look on what others thoughts are.
I just felt like Google is the best player out there in terms of Companies.
Seriously, Well played Google.
This is not a negative opinion, I am just awe-struck at its tactics.
See, Google is currently the biggest name in terms of development in Android, ML and multi-platform software but no one can say it being a monopoly due to its dedication to open source community.
Recently Android emerged out to be One of the Biggest , most advanced, trusted and loved Technology . It saw great achievements, and up till 2016-17, it was at its peek. BUT when the market started shifting towards multi-platform boons and Ai, it got its hands into that too with its flutter and kotlin environment
One could have a negative opinion about this, But i can't seem to engulf the vast amounts of positive situations i see in this:
1) this IO18 (and many months before that) saw ML/AI being incorporated in Android (also the arcore, proje tango and many more attempts in the past) meaning that Android will not officially "die". It will just become an extremely encouraged platform( not just limited to mobiles) and a beginning of the robot -human reality ( a mobile is handling everything of your everyday life: chats, music apps sxhedules, alarms, and with an actively interacting ML, it won't be long when Android comes installed in a green bug lime droid robot serving you tea xD). Meanwhile the market of Windows games may shift to mobiles or typically " Android games" (remember, Android won't be limited to mobiles)
2)java may or may not die. The animations and smooth flow it seems to provide is always appreciated but kotlin seems to do so too. As for the hard-core apps, they are usually written in c++ .So java is in the red zone
3) kotlin-native and Flutter will be the weapons of future , for sure. they will be developing multi-platform softwares and will be dividing the market of softwares into platform specific softwares(having better ml/ai interactions,animations) and platform independent apps(access and use anywhere softwares).
And where does google stand?Its the lord varys of game of thrones which just supports and enhances the people in the realm. So it benefits the most . That's a company for you, ladies and gentlemen! If seen from common eyes they seem to be the best company ever and our 1 true king but it can also be a very thick fur cloak hiding their negetive policies and tactics , if any.
Well played, Google.16
After 1 year of working as android dev and coding in java, finally switched to another startup where everything is in Kotlin where I will be the only one maintaining that project.
Me: This code has almost no comments
Senior dev: Code is pretty self explanatory
At least she spent 4 days with me and walked me through the code, so I'm not totally lost which is great!2
At the Android Developers under us:
Do you prefer the new Kotlin language or the good old Java? Because i'm currently learning Android Development with Java.
Would like to hear your opininion! :)5
"Kotlin, why the fuck would you want to introduce a better language for Android studio and still base it entirely on jvm, fuck you jetBrains and Google, you java dick sucking retards. "
I’ve got to build an app in 3 weeks that handles basic image editing and async requests. It’s gotta support both iOS and Android.
It’s also gotta scan barcodes.
What should I use?
Try and cram it through in native java/Kotlin and swift?
Something I’m missing?7
Haha, fuck you kotlin! and your null safety!
I was able to break it 😆
After reading about its syntax for over 2 weeks , i finally sat down to write a simple parsing app completely in kotlin. And now i don't know how, but i am able to store a null in a "val x:String" (i.e a non null variable)
I am not going to claim it as some miracle or discovery as some other ranters, it might be a mistake. I am just a 21 yo Android/java dev trying to re write my old ,tested java code to kotlin by myself, without any auto convert, in the middle of night when i am 99% asleep by brain.
I will try to raise an SO question with details, but all i used was a simple volley request returning heterogeneous data, a gson convertor and a single activity,
Right now i am buzzing off to my sleep11
Hi guys, I got some questions for you:
I'm a 17 years old guy from south Italy with 5 years of programming experience, mainly with Java and Kotlin. Since finding a well paid job here is soooo hard (especially when it comes to IT), I will surely go to another country (England, Sweden, Denmark and Norway in my list) once I get my scientific high school diploma. Here are the questions:
1) I have very high skills on JavaFX, both front-end and back-end. Is JavaFX commonly used in companies? Or should I move to other technologies like Android?
2) Will my diploma (plus a good amount of open source projects) be enough to find a job?
3) What certified English level is commonly required in these countries?5
Question here - what do you guys think of Kotlin?
Do you also think it'll be sufficient to learn Kotlin and not java to programm for Android?
I just began the transition, it's fun playing around with it, but a friend of mine wants to learn Kotlin to learn Android programming (and not java, he only has java basics).
What's your opinion on all this?12
What do you think about my language choice set for the future (knowing I want to work as a software and app developer) ? Anything to add / remove ?
- C++: Fast and well-documented, so I think it's a standard even in the next decades to come
- Java: Although I think that this language will more likely die in the next decade, I'll maybe keep this language because some dinosaurs enterprises still rely on it. Ah and mainly because it's still widely used in Android apps programming. For now.
Talking about Android, does learning Kotlin worth it ?
- Python: Will mainly use it for automation and prototyping, but nothing more, as it seems not to be widely use in the software development field (or it is ?). I'll also keep it for hobbies, however.
- Rust: This language seems to be a rising star in the industry since it is very clean, classic, as fast as C / C++ while introducing more safety. However I'll wait a bit for this one since it requires more complicated and abstract knowledge I do not have yet.
- C#: Seems to be a must when working on Windows software interfaces, so guess I'll have to learn this one. Will do so gladly, it looks better than Java17
Just learned how to write a for loop in kotlin and I now want to burn Java to the ground. When I first learned for loops in Java my brain almost imploded.2
Guys, What is the future of Kotlin? Is it a dead end? I mean many companies still use Java and google also released Dart for cross platform app development in previous years. Is there any point in learning Kotlin?17
since i finally have a laptop i can actually get away with doing mobile development... what would you guys, gals tell someone new to the whole Android dev world to use?
Java or Kotlin?
dont worry about my background, i usually just deep dive into anything new, but want to see what the general devRantsis is on the topic.
ive made it this far so... :D18
I'm a senior developer who wants to learn android development.
In your opinion, should I start with java or kotlin?42
Although iv only been developing in android for around 7 months yet I fail to see the appeal of Kotlin.
It has no real advantage over Java. In my opinion its fucking lazy code. It might look pretty but that's about it. So I don't see why employers are opening their arseholes for people with Kotlin experience.
Im pretty sure they are doing it because its "the next big thing". If you can write solid Java I dont know what the big deal is.. Maybe someone can shed some light on this..
Android studio can convert Java to Kotlin with one click. So No Mr employer I do not see your reason why you employed someone over me because he has Kotlin experience. Its fucked!! So that project I handed you... the one where I had pride in my ability to apply solid Java... Yes remember fucking Java everyone?!... well it works exactly the fucking same and in my opinion is much more verified and readable. SOOOO FUCK YOUUUU MR EMPLOYER!!!!! Go FuckYourStupidLittleKotlinBumChumsRightInTheirShitRiddenFuckHoles!!!!!!
Was recently in a motorcycle accident and haven't been cleared to go back to work yet so I'm trying to build my first Android app.
I don't know Java, XML, kotlin, Android studio, or what the fuck a Gradle is; but I figured I'd take my app idea and download Android studio then try winging everything from there.
Needless to say, I'm having a damn hard time lol. I have been watching firebase tutorials on YouTube to try and figure out how to add authentication to my app. I kinda got it working in the AVD. But my personal Google account has 2FA enabled so I can't seem to get the app to sign me out, or sign me back in. (I was able to authenticate once successfully.)
I have no idea if having 2FA enabled is even the problem. I tried turning on debugging and can't seem to figure out how to actually get the app to debug or get a debug console open.
I seriously feel like the world's biggest n00b right now. Going to go YouTube/Google how to get the debugging working. Then I'm off for a round of learning how to read a debug report!
Hahahaha... Kill me now -_-'2
Hi, so I want to get into Android App development.
I know the basics of Java and I have already written some simple apps with Java.
However I would like to get more serious with it and now I wonder if I should directly start writing apps in Kotlin or if I should write them in Java.7
C# devs go crazy once they found out that kotlin has got extension methods
and some other c#-like features
Just use Scala.
There's a reason books with titles like 'Scala for Java/C# refugees' exist3
If I don't know Java and no plan to learning it how should i learn kotlin?
I recently started android app development and i wanted to ask if you code entirely in java/kotlin or use xml+java/kotlin ?
I feel like to get better i should code entirely in java/kotlin. Am i wrong?3
ok so i though of clearing my basics regarding concurrency and async behavior in programming. my end goal was to somehow reach rxjava and kotlin coroutines since these are the 2 common frameworks used in professional android dev . AND DAMN! since last 2 days am exploring apis and how stuff works and i have million milesss to cover.
I mean , here is a list of all the ways by which java8 (current version is java 15) achieves concurrency :BlockingQueue,ArrayBlockingQueue,DelayQueue,LinkedBlockingQueue,PriorityBlockingQueue,SynchronousQueue,BlockingDeque,LinkedBlockingDeque,ConcurrentMap,ConcurrentNavigableMap,CountDownLatch, CyclicBarrier,Exchanger,Semaphore,ExecutorService,Callable,Future,ThreadPoolExecutor,ScheduledExecutorService,ForkJoinPool, Lock,ReadWriteLock,AtomicInteger,AtomicLong,AtomicReference,AtomicStampedReference,AtomicIntegerArray,AtomicLongArray,AtomicReferenceArray
I have always just used threads and executors. maybe once or twice a handler/ looper and never a thread pool. these all stuff are so fucking much!7
Can anyone point me to Android tutorials/resources using Kotlin? ( I don't know Java... Coming from iOS background)5
To Android developers who are employed, how's the industry with Kotlin? Are you guyz shifting to it or still stick to Java? And what are your thoughts about Kotlin future? Thanks.5
So is it feasible to develop iOS swift apps also using vscode? Is it smoother than Xcode?
What about android apps...android Studio is so slow, what all will I miss if I use vscode for Java/kotlin apps instead?4
Native Android Java/Kotlin I got covered but I need to go multi platform mobile. Your choice, why and why not?...
- React native
- Adobe Air
Looks like Android studio's artificial java to kotlin converter learned faster to write better kotlin than my shitty brain :/
People from java background, where did you learned to write efficient kotlin code and how?
Where to learn how to write that famous "kotlin's super precise and small , ugly ass anonymous looking code full of keywords , that only work when arranged in a particular pattern and defies my all previous knowledge of oop , java and good practices " code?
I really wish to learn, since android and google seems to be heading towards this beautiful new shit1
I give up! Been trying to solve this shit for a week and still failed:
Using Android Data Binding, two-way binding and when I compile I receive this error:
Unknown class: java.lang.String
It was working without issues before upgrading Android Studio.
Anyone has a clue how to solve this shit?
By the way I'm using Kotlin, on Java it doesn't produce errors, and I'm not going to convert my project to Java ...8
Hey guys. I am in a situation where I need to decide wether to take on a new project or not. And if not, how to turn down that client so that I would not burn any bridges. So I need your opinions on this matter in order to make the final decision.
To make things clear heres some background info. 10 months ago I quitted my fulltime position in another EU country and went back to my own home country. 10 months forward till today and I have my own ltd company which currently has 5 projects. Its doing pretty well money wise. All projects combined, I already earn more then I ever did and I need to work max 10 hours a week since all projects are remote projects so I dont waste time on useless meetings and etc. However I dont feel fulfilled or challenged anymore because surprise surprise doing well paid projects doesnt guarante your sense of fulfillment.
So I noticed that I have lots of spare time which I spend diving into rabbitholes with hobby projects. I decided that its time to scale my company and take on more projects and maybe even hire more people.
So I started searching for other projects I could work on (prefferibly remote projects or flexible ones where I could come in 2-3 days a week in office and work remotely rest of the week). Reason being that I am already out of sync with fulltime position lifestyle and I am totally result oriented, not punch in my hours and go home oriented.
For exampleIf i get my weekly tasks I prefer to do them in 1-2 days (even if it requires doing double shifts which rarely but happens) but then I want to have rest of the week off. Thats how my brain works and thats how Im wired. I cant stand fulltime positions especially in enterprise bigger companies where I come in and do maybe 2 hours of actual work everyday because of all useless meetings and blockers from backend/etc. Its soul crushing to me.
So I posted linkedin ads and started searching for new clients/projects. One month ago I went to an interview for an android project in a startup.
The project looked interesting enough. Main task was to rewrite their android app from java to kotlin. Apparently their current current app was built by a backend developer who wants to focus solely on backend.
So during the interview they showed me their app which was quite simple frontend wise but not so simple backend wise from what I was able to figure out.
Their project lead (also a backed guy) asked me my estimation of price and completion of task. I told them maybe 2-3 months to do everything properly.
Project lead was basically shocked because all other candidates told him they can rewrite the app from java to kotlin in 2-3 weeks. I told him that everything is possible but his app quality will suffer and for a better estimation he would we would need to sign an NDA so I could evaluate the costs. So we ended the interview.
After that we kept in touch for one month (it took them one month to google a generic NDA and sign it digitally with me).
So heres the redflags I noticed:
1. They dont respect my time. Wasted 1 month of my time and after signing NDA gave me 2days to estimate their project and go to a meeting and give them detailed info about what I can offer. I thats not a brain rape then I dont know what it is
2. They are changing initial conditions we talked about. We agreed on rewriting the codebase and be done with it. Now they prefer a fulltime worker who would be responsible for android app as his own product. So basically project lead was not able to find a fulltime dev so now hes trying to convert me (a company owner) to his fulltime worker.
3. Lack of respect. During the interview he started speaking in his own native language to me with some expression (he seemed pissed off at that moment when he switched languages).
4. Bad culture fit. As I said Im used to relaxed clients and projects where I dont need to be chained to a desk a monitored and be micromanaged. I mean lets sign a contract give me access to your codebase and tell me what to do, I will produce results and lets be done with it.
5. Project lead is a backend guy who doesnt understand how complicated android apps can be. No architecture and no unit tests are in his frontend app. He doesnt care about writing proper app since he ships it in his own device so he doesnt need to worry about supporting custom devices or different api levels of android and etc. But not having any architecture? Cmon.
So basically I am confused. Project lead needs a fulltime dev but hes in contact with me in hopes that I would sign a fulltime contract. But how I can work fulltime if all what I can see are redflags?
Basicaly I thinkthis was a misundersanding. Im searching for fulltime remote projects and hes offering fulltime inhouse projects. Project lead never outsourced so hes confused as well.
As you can see decision is already basically made to turn him down, I just need to know how to tell him to fck off in the most polite manner and thats it.6
Why do developers out there think java is a write off just because of kotlin's existence? Java isn't going anywhere fam, you know how large the community of Java programmers is? You'll hardly find stackoverflow answers written in kotlin. Kotlin is the official language just as c# is for Microsoft but that doesn't stop anyone from writing windows software with java. Stop scaring potential java programmers with "ANDroId iS rOotiNG For kotlIN" for fucks sake.5
why is kotlin picking up so much hype is it actually completely stable now? Would it be better to develop android apps in kotlin rather than Java for my next app? Is java going to become obsolete/deprecated for android?1
I have been an android developer since long time, yet android migrate everything from Java to Kotlin
But am really worried to migrate everything from Java to Kotlin or begin this phase can you please help and tell me where is the best way to learn kotlin and get easily adapted3
Why are devs at google making it hard for android developers? They release libraries so frequently and completely overhaul everything. It was fine till a limit. Now again they are releasing jetpack compose which is a completely new thing. I don't have problem learning new things but the rate at which they release new stuff is far swift than other frameworks. For example they release a new dependency injection hilt while recruiters still look for dagger 2. Android is just getting overwhelming. What are your thoughts?6
For interested developers in kotlin:
Kotlin 1.4 Online Event, October 12–15, 2020
Four days of deep diving into the technologies behind Kotlin’s latest release with Q&A sessions and 1-to-1 booths. https://kotlinlang.org/lp/event-14/
I recently started learning Android development with Java, but now I'm confused if I should learn kotlin as well. What do you guys think? Kotlin > Java?4
Everything is shit and I have to work drive thru till 11.15pm.
Everything appears to require js at one point or another (though kotlin requires groovy which, in the intellij IDE, the template it COMES with is fucking broken from the start)
Java seems like an option, lots of jobs available, but I need netbeans for desktop (javafx) and Android Studio
separately in order to do anything. And Android Studio now uses, of all things...FUCKING GROOVY.
*cocks gunfinger and points in mouth*
why must every fucking thing be it's own DSL and make everything about the fucking ceremony of configuration over
Haven't any of these fucking cocksuckers heard of MAKE? Or do they just masturbate over how intelligent and smart they are for having reinvented the god damn WHEEL?
I'll see you at the drive through. Will that be all for today?9
Hello!. I have a little tech app idea I'll love to startup. I made an educated guess that my target users are mostly on the android platform. At least 70-80%.Now I don't have funds to get a development team and I want to keep the expenses to the barest minimum. I have a little tech background. I have, used html, css, c# in the past. I always hated Java in school. But it seems I have to embrace it or Kotlin for the development of the app. I want to be able to build at least the MVP and try to gain traction. I am also thinking about cross platform options to cater for both Android and the few iOS users we may have. React Native and Flutter comes to mind. I also think I can get someone highly technical than myself as a co-founder to help. I will appreciate it if you can drop your 2 cents.16
You look everywhere to be puzzled of what went wrong and realise that you missed a semi colon assuming that language to be semi colon independent.
I feel that it's better to develop in Kotlin, for android, as a beginner, given the recent announcement.
Any other suggestions?12
I'm building an Android App and need to implement multi option selection using images. Tried google searching "android libraries for multi-option selection using images as option items just like Medium.com" but i keep getting links for image picker libraries instead.
Have you ever come across any? cus i'm not ready to implement that from scratch. Thankee2
Tips for learning 2 languages at once? I'm learning Java in school, and I'd like to learn Kotlin as well. I know they're similar, so my main concern is just mismatching syntax.4
I'm learning Kotlin while trying out Android Things and that sparked my interest in learning more about Java platform again. I tripped upon the news that Oracle had change their commercial plans for the platform by going with the rolling release model and limiting LTS releases for paying customers.
Java SE 8 was one of those former LTS releases that was on my computer, leaving me vulnerable, despite that version still being the most compatible with many applications, and that's been on my computer well passed the date they cut off public support. And I'm, like, "WTF!?"
Luckily this is when open source shines at it's brightest. Both the home brew and corporations, such as Amazon and IBM, alike - mostly the latter - both agreed to create their own LTS releases using the OpenJDK code and all disturbing to the public FOR FREE with no strings attached and the sources opened. I'm sure Richard Stallman is smiling with glee.
It isn't a total finger towards Oracle. Java SE is based on OpenJDK with no difference between the two anymore aside from loss of LTS support from the public - that's it. So Oracle still benefits despite the retaliation. Probably?
Did Oracle learn nothing from OpenOffice? If the point was to get users to pay for security then they've failed in the long run because Java is open source. People have used that fact to create their own free distributions that bypass their paywall, making the need to go through Oracle pointless. And I'm glad. Open source aside, security is a big issue these days and the last thing people need is yet another thing to subscribe too.1
I recently started learning Kotlin and while I like it a lot already I find it to be a really strange language at the same time. This is coming from someone mostly doing numeric stuff in Python (for my PhD) and Android development in Java (my personal side project, which I'm currently rewriting in Kotlin).
I know android java, kotlin.. So for iOs development what should I learn?
Which and why?
I would prefer the one with lowest learning curve.10
Not sure if this is against the rules (can’t find it) but taking the risk to post this here.
I’m android(kotlin/java) and Golang Developer looking for a remote job in any company. I’m really bored and tired of not doing anything daily.
Here’s my resume on google drive: https://drive.google.com/file/d/...5
Hey I am just curious, do you think is there any good reason to stick to Java now that Google officially supports kotlin?
Asking Android developers: I want to learn how to make Android apps. I know a little bit of Java and thus kotlin too. Which resources do you guys recommend?5
Can someone recommend a good, free and easy to use service (web or windows app) for mobile apps prototype, mockups, etc. I want to create a visually rich and possibly clickable prototype for a mobile app idea before development.13
Why oh why, why does my project not work... 2 hours later, "Oh Damn, I forgot a semicolon. That's it, I'm switching to Kotlin."2
In Kotlin or Java, I have a list of items that have an ID property. This list is generated based on another list. Now I get a List of mentioned list items and I want to select all items in the parent list, selecting by ID equality.
Is there a more elegant way than just iterating the parent lost for each derived item? Thank you :)5
I'm building an Android app from ground up targeting to have functionalities added without much effort in succeeding phases.
What I'm pissed about mobile development at the moment though, is its lack of structured code base that is easy to follow. Unlike web where codes are modularized and well placed, in mobile, I kept going back and fort in different modules to see how they are used in all places in the project which made it tedious as time goes.
So I kept a notepad keep track of detailed flow. However, once I go back at the notes to place them on top of your head, the almost spaghetti-like structure just becomes very hard to track. For me it doesn't follow a pattern and that developers are free to do what ever they wish so as long as it can run in the device or emulator.
For instance, implementing concurrency as well as dependency management and a Clean architecture is such a pain. I hope i can relate to someone here.
If only there is a standardized way of structuring codes in android in Java or Kotlin (haven't tried this), there would be hope for me. So if anyone can provide a good, readable, reliable android project that I can start building my project on top of, your help will be greatly appreciated! Thanks for reading.
I just got to college and can do web dev fairly well (Mern stack mostly). But tbh I am now more interested in being an app developer. Should I try to learn React Native/Flutter or Kotlin/Swift3
Wait someone said Java is going downhill and new projects aren't really made in Java anymore outside of Android? The fuck I'm just learning Java. Granted I really am learning it because I want to make stuff for Android but again wtf? Will this become its only use at some point til Kotlin takes over?3
Devs can you point me to the topics that i should know in web dev? Kind of being hovering across a lot of different stuff, but don't know the actual path to follow . I kind of wish to become a full stack dev( not just the web) / Systems engineer someday and i am hoping to get a job asap
About me :
- oop/strong typing language guy. Knows enough java/kotlin/android dev to make decent Android apps, with confidence to apply on Android dev jobs
- knows enough python3 to understand its classes/functions. (But not more)
- knows some html css and client side js to make static websites, though my knowledge in this domain is not sequential but rather learning whatever i found interesting, so don't really get confidence to apply on a web dev job when i see an opening
- knows very basics of backend development in flask/php. Although worked with SAAS solutions liked firebase/aws
- knows some basics of data analysis6
should i learn a new language such as python? node? or some new framework/library like react?
or i should stick with what i already know?7
I would like to learn how to make a mobile app, but I do not know what to choose. Some say java, some say kotlin, then some react native and some flutter. I just wanted to ask for advice. And btw Laravel, Js, Jquery, Ajax and Cordova Apache are all I know so far.7
I am feeling a lot doubtful right now.
I am an average undergrad student who has been dedicating efforts in java/Android for most of my college life.
As of now i have decent command over java , launched 2 simple apps on playstore, worked as an android dev intern in 3 companies and make decent medium complexity apps. I will say i am 40-60% down the path of an expert native Android dev.
However apart from Android, am dumb as a stick. I know shit about ai,ml, web dev, js , react, hybrid stuff, and am not very good with competitive programming and system topics ( os, Algorithms, networking, etc)
So this closes a lot of doors for me. I can't apply to some top tier companies as they would either want expert competitive skills or expert Android dev skills.
I had bad experiences with startups which are usually willing take rejected students like me for the post of a droid dev... there is usually low packages , high pressure, and treatment like a slave
So i am very unsure what to do next. I have tried to learn web dev/ ai-ml-data sciences. They are not very interesting to me, but again, what is interest really :/
What should be my focus now?
A) I could be learning competitive and other interview related topics so that i could crack interviews of top companies , and later try to get a position of android developer there.
B) i could focus on become better in Android and start learning things that i don't know like rx, kotlin, etc. I could then hope to crack interview of medium sized app dev companies which would mainly focus on my android knowledge in their interviews
C) i could increase my skill set and learn web dev or ai/ml topics to increase my recruiter pool. It would be like option B, but i will have more medium sized companies willing to take me.
Currently i am in a shit storm. I am about to go into a mass recruiter company in which i have heard would be doing more or less data entry work3
How does Kotlin compare to Java? Got experience / opinions worth sharing about them?
Always wanted to make some android apps as hobby but Java was grossing me out.4
Android devs who started with java : how much have you been comfortable with kotlin? What is your approach towards using new libraries : reading theire docs/code in java version and then implementing in kotlin yourself or are you comfortable in understanding there docs in kotlin itself?4
Has anyone got experience in android development with both kotlin and java?
I am want to know if there are big differences if I migrate to kotlin. I have started learning Kotlin and it is unbelievable great so far.
Java or kotlin for android mobile development ? And why ? I am still not convinced by kotlin at least just by myself but is it worth it ?8
So I have negligible experience doing mobile app development (simplish hello world Java app few years ago).
What's your advice to start getting into it? Flutter? Kotlin? I honestly dont have a clue. I want to target Android at first but very like this needs to support iOS as well.
I'm quite the experienced dev so I dont need some something to hold my hand, yet I dont have the time currently to fight a steep learning curve.3
Is Kotlin the new hype? Should I go for java 8 or kotlin for development of android app? Also does anyone know any good course for ui/ux development(I am a backend developer)
