I just started learning Kotlin for a week or two and suddenly Google announced Kotlin will be officially supported for Android development.
I'm excited.6 -
I've caught the efficiency bug.
I recently started a minimum wage job to get my life back in order after a failed 2 year project (post mortem: next time bring more cash for a longer runway)
I've noticed this thing I do at every job, where I see inefficiency and I think "how can I use technology to automate myself out of this job?"
My first ever application was in C++ for college (a BASIC interpreter) and it's been so long I've since forgotten the language.
But after a while every language starts to look like every other language, and you start to wonder if maybe the reason you never seriously went anywhere as a programmer was because you never really were cut out for it.
Code monkey, sure. Programmer? Dunno, maybe I just suffer from imposter syndrome.
So a few years back I worked at a retail chain. Nothing as big as walmart, but they have well over 10k store locations. They had two IBM handscanners per store, old grungy ugly things, and one of these machines would inevitably be broken, lost or in need of upgrade/replacement about once a year, per location. District manager, who I hit it off with, and made a point of building report with, told me they were paying something like $1500 a piece.
After a programming dry spell, I picked up 'coding' with MIT app inventor. Built a 'mostly complete' inventory management app over the course of a month, and waited for the right time.
The day of a big store audit, (and the day before a multi-regional meeting), I made sure I was in-store at the same time as my district manager, so he could 'stumble upon' me working, scanning in and pricing items into the app.
Naturally he asked about it, and I had the numbers, the print outs, and the app itself to show him. He seemed impressed by what amounted to a code monkeys 'non-code' solution for a problem they had.
Long story short, he does what I expected, runs it by the other regionals and middle executives at the meeting, and six months later they had invested in a full blown in house app, cutting IBM out of the mix I presume.
From what I understand they now use the app throughout the entire store chain.
So if you work at IBM, sorry, that contract you lost for handscanners at 10k+ stores? Yeah that was my fault (and MIT app inventor).
They say software is 'eating the world' but it really goes to show, for a lot of 'almost coders' and 'code monkeys' half our problem is dealing with setup and platform boilerplate. I think in the future that a lot of jobs are either going to be created or destroyed thanks to better 'low code' solutions, and it seems to be a big potential future market.
In the mean while I've realized, while working on side projects, that maybe I can do this after all, and taken up Kotlin. I want to do a couple of apps for efficiency and store tracking at my current employer to see if I'm capable and not just an mit app-inventor codemonkey after all.
I'm hoping, by demonstrating what I can do, I can use that as a springboard into an internal programming position at my current gig (which seems to be a company thats moving towards a more tech oriented approach to efficiency and management). Also watching money walk out the door due to inefficiency kinda pisses me off, and the thought of fixing those issues sounds really interesting. At the end of the day I just like learning new technologies, and maybe this is all just an excuse to pick up something new after spending so long on less serious work.
I still have a ways to go, but the prospect of working on B2B, and being able to offer technological solutions to common and recurring business needs excites the hell out of me..as cringy and over-repeated as that may sound.5 -

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 -
You know how cities hang all sorts of decorations wherever possible before Christmas? Well, it looks like people of Kekava, Latvia, are very big fans of Kotlin and find it's logo to be festive!

So I've decided to go about converting a Java project that I've been working on to Kotlin a little bit at a time. I started out with basic entity classes converting them to simple `data class`es in Kotlin.
Eventually, I got to my first beast of a class to refactor. This class had over 40 service classes depending on it, so even a little hiccup would throw everything into chaos.
I finish all of the changes on all of the dependent classes, update the tests, and the configurations (as necessary), and I was finally ready to spin up the app to test for any breaking changes I may have introduced...
Well - I broke everything! But I was sure I couldn't have! So what the hell happened?
Turns out that as I was building my project with a Gradle watch, at one point something failed to compile, which threw an unhandled exception in the gradle daemon that was never reported.
So when I tried to run my app, gradle would continually re-throw the error in the app I asked it to run...
After turning the daemon off and on again, the app worked like a charm.

Kotlin! I recently transitioned to kotlin for Android Development and it's such an exciting journey!!!3
-
IntelliJ!! In my opinion its the best IDE for Java and Kotlin and it supports you to code better
And I got it for free because I'm a student :D5 -
Kotlin
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 -

When I was first learning Kotlin, I was so excited about its simpleness and power compared to Java.1

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 DIFFERENCE

Truth: You will regret not using Kotlin as soon as possible. Don't deprive yourself of pleasant development and productivity boost.5

While getting a pro in Kotlin, I started using
when(condition) {
true -> doOneThing()
false -> {
xyz = whatEver()
blaBla()
}
}
instead of simple if-else.
It looks nice but also distracting.
What is your opinion on that?
I guess most will be like:

Oh boy, kotlin and its world of statics and lambdas are glorious 💗💗💗
I just finished this attendence counter app i have been working on for last 4 days.its quite simple so i tried to add as much constraints as possible:
-Good practices and minimal warningy
-Room database
-Viewmodel and livedata
-constraint layout
-everything in kotlin
Although i already have worked with room and livedata previously but i dont even have a hello world experience in kotlin . However it doesn't felt that bad tho for a newbie
Every code here is so small . Synthetic binding? Love at first sight.Although at some places its irritating , not having ?: Operator or its ugly 'when' logic, but overall its Awesome!!7 -

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.
Its super easy to learn. It took me about 2 hours to get into it. It combines concepts from java, javascript, c# and maybe a few other languages to form a modern jvm 1.6 compatible typesafe language.
Android dev is fun again!2 -
Still tryin to learn Java and suddenly appears Kotlin... I sometimes want to stop the frig world :'v5

why did kotlin documents use these fucking idiotic font that combines 2 characters into one stupid looking icon? how is it friendly to a noob? how am i suppose to know how exactly am I suppose to input these piece of shit?
21 -
I have to say, Kotlin is getting interesting now. At first i was like "WTF is this shit", but now im like "TF, did i just create a data class with 2 lines of code as opposed to the 14 i would have using JAVA? TF you've been Kotlin?"
-
I will never forget that screenshot of a corrupt jar file viewed in 7-Zip containing something with a compressed size of 19 bytes, which would result in more than 1 TB uncompressed
Things like these are why I'm still breathing12 -
Kotlin makes the development experience so much better. Humans are creatures of habit. Some don't want to change what they already know. RIP to those who still start their project in Java and do not want to adapt in this competitive world. :/9

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 -
Gotta love kotlin!
@osiris1337 the refactoring is going great
I had a 80 lines long model class with all the getters and setters and Parcelable interface implemented
and all of that converted to kotlin like this
@-psr another reason, small and readable code ^_^

People refusing to learn an improved programming language or technology, because it might contradict to what they "already know" and you're just there mastering it and appreciating its advantages that you will never learn if you had a closed mindset.4

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!!
Story is:
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 -
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

Started a small personal Android project after 1 year of not coding android.
Create project -> hmm -> should i... try kotlin -> install plugin -> new project. This thing seems to have a much clear syntax, unexpected.3 -
Today I was trying to convince a colleague that:
fun example(){
if(thing){
//Do something
}
}
Is stupid because it should be
fun example() {
if (thing) {
//Do something
}
}
It's the small things that are the most frustrating14 -
So today I decided to try out Kotlin on Android. Hacked up a little Textview-Button app. AMAZED with the little code.

Having to write Swift and Kotlin for a while at work and now switching back to working on web technologies (for a different job), I would say JavaScript is ugly.4

Kotlin and mother tongue
In my mother tongue (my first language which is Kikuyu) we do not have the letter L in our alphabet thus meaning L and R to us is similar thus pronounced the same.
Then Kotlin makes life hard for devs who got a mother influence in their speech from my tribe. Was having a talk with fellow dev who is my tribe mate and we had an issue agreeing between val and var hehe.
We had to write it down to tell which is which.
Thankyou Kotlin for making my day.6 -
Such variable names
much helpful
very wow!
Either I need to download sdk source code for var names to show up correctly or I need to memorize which is for what :\

Sorry, need to vent.
In my current project I'm using two main libraries [slack client and k8s client], both official. And they both suck!
Okay, okay, their code doesn't really suck [apart from k8s severely violating Liskov's principle!]. The sucky part is not really their fault. It's the commonly used 3rd-party library that's fucked up.
Okhttp3
yeah yeah, here come all the booos. Let them all out.
1. In websockets it hard-caps frame size to 16mb w/o an ability to change it. So.. Forget about unchunked file transfers there... What's even worse - they close the websocket if the frame size exceeds that limit. Yep, instead of failing to send it kills the conn.
2. In websockets they are writing data completely async. Without any control handles.. No clue when the write starts, completes or fails. No callbacks, no promises, no nothing other feedback
3. In http requests they are splitting my request into multiple buffers. This fucks up the slack cluent, as I cannot post messages over 4050 chars in size . Thanks to the okhttp these long texts get split into multiple messages. Which effectively fucks up formatting [bold, italic, codeblocks, links,...], as the formatted blocks get torn apart. [didn't investigate this deeper: it's friday evening and it's kotlin, not java, so I saved myself from the trouble of parsing yet unknown syntax]
yes, okhttp is probably a good library for the most of it. Yes, people like it, but hell, these corner cases and weird design decisions drive me mad!
And it's not like I could swap it with anynother lib.. I don't depend on it -- other libs I need do! -
Why the heck would you allow (or need) nested block comments? Imo this is a major design flaw in the kotlin linter.
I always use /*... //*/ so I can remove the comment starter w/o having to remove the comment end, but kotlin just starts a second, nested comment there.
Java, C, Cpp, C#, JS,... Not one of these uses nested block comments. I think jetbrains was just lazy?
I mean, I know why such stuff happens. I also developed DSLs in MPS, but there sure are ways to go around such things..
7 -
I used to be a Java fanboy.
After seeing the modern things one can do with other languages I am just disappointed, that Java is so old-fashioned.
Some would say "BUT IT HAS LAMBDAS".
Good, that we have lambdas. We don't have optional parameters or objects (like in JS's {} or PHP's stdClass).
JVM may have many advantages, but I think, that Java is slowly dying although it is kept alive by some companies, still using Java in prod.
I think, that Kotlin is, what Java should have been.
I hope, that my wishes will be implemented in Java 10. If not, Java is considered as dead.8 -
Been watching The Lord of the Rings trilogy since yesterday for the third time in my life. I shed a tear at the end. That movie is as good today as it was 15 years ago. Awesome.
Now, to make this post relevant, im going to close VLC media player, open Android Studio and go on a Kotlin (which is becoming more and more like Gandalf the White) journey2 -
I'm about to lose my freaking mind on intellij. Ran my tests yesterday and everything was good. I added a new method and a new test case today and suddenly no tests are found. Well they didn't go anywhere!! "Class not found, empty test suite" ... Lies! I've been messing with configurations for over an hour now. I just want to run my tests...1
-
Cocktail for disaster:
- TDD
- Mocking
- Multithreading
- Averagely well written, testable code
- All tests pass
- One test methods still shows some vague stacktrace in a worker thread ❌ but the test passes ✅
- Run only that test method and no stacktrace.
So I've been pulling my hair for the last two days trying to figure out what was throwing in that test method. Turns out that thanks to the multithreading going on, some other, similar method threw the exception in parallel. And apparently a different test method was already running when the exception was finally caught.

When I discovered that, it was fixed in a minute. 😭1 -

I was a Project Manager, studied my a$$ off at 38 to become a mobile developer. Built production apps in Java, React Native. I've studied Kotlin and Flutter. Then my company almost went belly up and I had to scramble to find a job to support my family. Back to being a PM which I hate. Started with Swift because my son is old enough to play with Swift Playgrounds and thinking about making a break back into dev. Every post I see on Twitter is about Flutter, maybe RN, but not much Native iOS. Is it wrong that I'm loving it thus far? What's the future for Native iOS and Android developers?2

I want to learn a new programming language. What should I learn? I am torn between Kotling, Go and Scala.
Or should I just learn a new JS framework? ;)20 -
Im learning kotlin but heres what i dont get..
is it a completely new language that uses jvm concept like java or is it a template over java with extra stuff like C++ and C.
when i import a library in kotlin that exists in the java sdk does it use that or all the libraries are made for kotlin.
is kotlin java++ basically or is it something completely different
sorry if its a dumb question still nee at this8 -
I really hate people that don't document well their 'inventions'.
Let's take for example kotlinx.serialization library. It's a self-obvious fact that there are at least two things that will make anyone suffer: generics and polymorphism. So, they must be on the front page. Solved. With a recipe. Ready to use.
And what do we have? One mention somewhere in docs and an amazing test that 'explains' 'everything':
https://github.com/Kotlin/...

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 -

our new cto is advocating to start migrating our existing and any upcoming new features from php to kotlin.
I tried looking into kotlin but it just doesnt feel nice to me. call me an idiot for actually enjoying php or java but i really dont feel like using something other than them.
i don't want to write Kotlin or Go or anything other than php or java which I already feel extremely comfortable with.
Maybe id love writing Rust even tho im new to it but anyway...i got too used to my comfort zone... and very few *new* things tend to interest me anymore.

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 -

In your opinion, should I start with java or kotlin?41 -
Is kotlin worth coding in? Or is plain Java better? There are many people here coding in kotlin what made you change to kotlin from Java or from anything else? Is there a specific reason? Speed? Stability? Anything? Is it worth using it instead of Java?9

I'm learning Kotlin through a Udemy course and the course instructor has such an awful accent that it's often difficult to even understand what he's saying. When he says "string" it sounds like he's saying "sit ring." 😧

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!!!!!!

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 -
Started making an Android app for the first time a few days ago and wanted a button in a fragment to trigger a function. Easy enough right? Well not for me...
-Thought if the button is in fragment_xyz.xml the function should be in xyz.kt right?
-Wrote the function and told the button to run it when clicked.
-Tested the button and the app crahsed.
-Spent 3+ hours trying to find the bug.
-Eh fuck it might as well copy paste it from the fragments file to the action the viewpager showing the fragment is on.
-Works perfectly fine first try.
-😑
I spent three fucking hours googling that and trying to debug that while I could have been doing so much more on ither parts of the app...
I mean at least I know now for the future? -
Started learning Android development in Kotlin.
My first impressions:
- Kotlin is good, but class syntax is not very appealing
- Overall it seems to be quite easy, at least the basic stuff
- Android Studio is a fucking memory hog, RIP my RAM
- As good IntelliJ is as bad is Android Studio somehow
- Emulator seems to be really advanced which I like9 -
If I don't know Java and no plan to learning it how should i learn kotlin?
No experience with c or c++ either. No programming experience at all. Because HTML and CSS aren't programming so yeh. plan to learn JavaScript next month after my fucking exam.6 -
Can anyone point me to Android tutorials/resources using Kotlin? ( I don't know Java... Coming from iOS background)5
-
I wonder if Google released Flutter because they can't let Facebook have all the fun with react native. Or maybe they did it because they had fushia os in mind for a loooong time. Or maybe because they realized that the android api is overly complicated and the Dart way is easier. Or maybe they did it for the lolz.

I want to rewrite one of my projects (a password manager) from Go to Kotlin or Python.
Which one of the 2 should I choose?
I know nearly nothing about both.1 -
#kotlin
when you don't know whether you are writing code, or is it a comment.
doing #java for couple of years has its effects. -

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 -
"My code is explain itself. Well, I need no comments to understand it."
I don't care if you wan't to write comments or not; If don't write any then i don't care because fuck you and your code.
May it be java, kotlin, python, javascript or anyother language, you think "everyone can read", i hope you'll never find anyone who has to deal with you and your cancerous code.7 -
How can you learn a lot of things?
i'm trying to learn kotlin and i think i'm forgetting python.
is it happens to you?
or i'm stupid?9 -
Word of advice:
Whenever you plan you invest a considerable amount of time in learning a new language make sure that its well documented and has a good support.1 -
I was just clicking trough oracle's docs, on a page which had to do with manifest&sealing (kotlin/java)

I can't shift to kotlin because my company is fucking around on being on Java 7 (with retrolamdas *wink*), where it takes 10 minutes for a gradle build.1

Hello everyone.
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 -
The Kotlin Koans tutorials are actually really helpful. This language feels really smooth; I like it. Now to actually make something with it...2

I started to learn Kotlin today and am already confused:
Is there any difference between between Ant, Maven and Gradle?2 -

Look up the Kotlin Puzzlers presentations by Anton Keks, in which he shows the strangest behaviours of the Kotlin compiler. Bizarre syntax, strange results, bugs, etc. Some aren't even edge cases. And he's wearing a captain's hat.

So, I’m on interview 3 with a company looking to build a cross platform app.
They posed the question of what we should use to build it; React Native or Flutter? Or just go native with Swift and Kotlin individually? What’s your thoughts?
I’m really interested in this conversation.2 -
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 -
Any Kotlin fans out here? What's your favourite feature?
To me: coroutines and the flow API. I can't wait for the state flow and shared flow APIs to be released. Goodbye Rx! It'll come probably in the next release, which might come in a week already, because then JetBrains (Kotlin developer) hosts their online alternative to KotlinConf.7 -
Situation: I'm a junior, working at company X since about the start of this year. We have a mixed team of native Android and native iOS developers. The architectural design decision was to build a separate iOS and a separate Android app.
Recently, during a problem solve session with other teams, other developers were complaining: why not use React Native, why not use Xamarin, why not use PhoneGap.
I'm so sick of this shit, if you have your users in mind, if you care about UX and UI and if you care about building an actually good app, GO NATIVE.5 -
I am starting to get a hang of kotlin at last.
But its gives such a weird feeling. all these years i was writing great code that could lift mountains without failing. And now this language comes in, says "fuck you, we must prevent null and make everything static/final asap!!"
Like static inner classes? Why would we even want them? Well the lady says am wrong, am wrong. -
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 -
As much as i love kotlin, i hate that you dont have static functions like in java. You have to put them in a companion object or write them in extension functions outside of the class.
Also when working with generics (lets say T) you cant call T::class.java unless you are in an inlined function and mark T as refeied. This is not the case in java i think. I havent checked.1 -
Git repositories? What is the best online for free
Android Studio + Kotlin
Hey guys
So, I'm thinking on starting programming again... slowly cause of Burn out
I'll be homesick now for a while and I want to start coding again.
I've been making Apps for Android in App Inventor, but now I want to make stuff that sincerely will be hard on a complete visual programming language.
So, I'll be starting to learn kotlin
My problem now is that I don't do any really programming for years, and most of my knowledge is from 1990's. I want to put my code in a git repository but GitHub doesn't have a free option and I can't spend money now, since I'll gain a lot less.
What are the best alternatives online, or tricks, like online VMs
thanks for the time11 -
TFW a method is acting weirdly, and after much investigation you find that you forgot to change the contents of the method when you copied it.

Looking into Kotlin, and it seems pretty cool, but I just can't get over how unnatural and annoying the mapOf syntax is.
In JavaScript: const obj = { a: 1, b: { c: 3, d: 4 } }
In Kotlin: val obj = mapOf("a" to 1, "b" to mapOf("c" to 3, "d" to 4))6 -

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
-
"Learning" kotlin for android dev has been a wild ride yet. Kotlin is kinda cool, a mix between python and Java but with many nice features. Then again there are kotlin features on which I just scratch my head like data classes and companion objects.
And then for android (not kotlin specific) I see things like calling Timepicker(...) or Timepicker Dialog(...) without assigning it to a variable and wonder how that can even work. Can someone explain? There's no creation method, static method or anything?
I feel like a competent and incompetent dev at the same time.3 -
What do you think about developing apps for both IOS and Android in Flutter? Should I give it a try switching some weeks from Kotlin (in Android)?7
-
I recently performed a huge refactoring effort on a Java project converting both the persistence and utility layers to Kotlin. Gotta say, I think I'm starting to fall in love with programming again!
Putting aside how pretty it is now, I've reduced those two layers by over 2400 lines of code -
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. Thankee

I've taken an interest in Android development and have discovered the existence of Flutter a while back. The thing is, I'm midway into learning Kotlin. Should I stick with it for now and then consider Flutter after I've learned the ropes of Android development or should I consider it now? I know I'll have to learn Dart which is different from Kotlin.4
-
Don't know if Kotlin is actually a lang for the future or again some hipe-shit.
Tried some tutorials, and I reeeaaally liked it.
Any toughts?3 -

prediction question: how long do you think until JavaScript goes away, and what language do you think will replace it as the de facto web language? I know Dart is aiming to fill that niche, as well as even Kotlin/JS and/or Kotlin/WebAssembly7

FFS Kotlin, did you completely forget to mention how to create an object in js or did you seriously not think about the usage of the `new` operator when writing that compiler.
I just wanted to use that glorious when statement for my discord bot. Not to mention that retarded tutorial with incredible gaps and cyclic references and now this. -
Hey I am just curious, do you think is there any good reason to stick to Java now that Google officially supports kotlin?
Thanks1 -
I finally created a kotlin android app for a simple project idea, just personal usage. Beginner level. Quite a good and bad experience.
Functionality is done, just sucks with UI, as I'm not proficient enough with styling on android.
The result is a predefined purple action bar at the top, an almost white text section right below it with *very* light-grey textview descriptions (you can guess how visible they are on my phone...). Center is a big recyclerview, which in android studio has white background with dark grey text items, yet is black on my phone with white text items. At the bottom 3 text inputs and a centered purple "add" button.
... It's a mess as long as you don't know how to design and style on android studio.2 -
everytime i try to learn kotlin, i can only think WTF is happening, why should it be happening?
after wasting last 4 hours, i came to this conclusion table regarding kotlin var and val notation.
And now my fucking compiler is saying that i can rather write :
val x:Int
and initialize it later, when i thought val is immutable and must be initialized at the beginning only(like public static final int x =5)
Who the fuck are those people that like this stupid language? why would you say some variable as immutable(meaning which can be changed 0 Times "ONCE" ASSIGNED A VALUE ) and when i can create a program with a variable that never got ASSIGNED A VALUE EVEN ONCE??

"if compiler can infer this, there is no need to add "x ->" , simply use it" ..AAAGHH FUCK YOUUUUU KOTLIN!! what else should i fucking not write? why do't you take a number of my employee and ask his requirements, maybe add a ShoppingKartApp.kt in your compiler next time? it will be completely inferred when i write "Fuck you" in the gradle.
And fucking companies are promoting this! I wonder how those devs are living there
Person A knows only that lambda is
{name:Type,name:Type->code}, and thus writes a clean code.
Person B comes says "This shit suck", writes "{ acc, i -> acc + " " + i }" ,goes away
Person A : "wtf is this shit? why it works?"
Please for the love of god, follow some rules! My first language was python, i love its zen:
- Beautiful is better than ugly.
- Simple is better than complex.
- Readability counts.
- Special cases aren't special enough to break the rules.
- There should be one-- and preferably only one --obvious way to do it.
- If the implementation is hard to explain, it's a bad idea.
-...
I just wish it follows at least one thing from python's zen : "There should be one-- and preferably only one --obvious way to do it."3 -

I have been doing android dev for quite a time now and have started to understand/appreciate a few things that I previously hated (Like Kotlin) . so am not sure where would be my stance regarding this rant in upcoming months, but FUCK DEPENDENCY INJECTION FRAMEWORKS!!
dependency injection is rightly said to be a $25 term for a 25 cents concept. If i start refactoring my old apps today to "follow DI principles", they would require just 5-10% refactoring and i will end up with much more testable code.
But integrating dagger in my apps? Oh please fuck me straight instead. That thing is so overly complicated and confusing. Why would you trust compiler to inject instances in YOUR LOGIC ? it was YOUR LOGIC that guided the compiler, remember?
I am yet to work on a product of scale where frameworks like dagger or koin made even a slightest of sense.
Currently it just feels like another bad choice we took between "simple but verbose" and "complicated but pretty to look at"
The way this framework makes me think like a compiler than a programmer somehow reminds me of this beautiful article i read:
https://theatlantic.com/technology/...3 -
Android Studio 3.2b4 once again regressed on "No tests found" bug for Kotlin projects.

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.

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).

Can someone please explain the benefits of this in Kotlin:
var x = if(a !=b) {
z
}else{
y
}
Even for a conditions with one line body it looks bad in reading and getting a clue of what does this do.
I mean whats wrong with:
var x: MyObject
if(a!=b){
x = y
}else{
x = z
}
Even in switch cases (or as kotlin calls: when) True one return source, but now good luck finding the last line that is the actual returned value ...16 -

Has anyone got experience in android development with both kotlin and java?

i can never understand the theme behind kotlin.
THEY DON'T HAVE A FUCKING TERNARY OPERATOR!!![?:]
Like before realizing this, i thought yeah jetbrains has decided to make android development a privileged hobby and non beginner friendly , so its now creating an encoding like language, in the false theme of " reducing code size"
But now they remove WORLDWIDE KNOWN, OPTIMIZED , EASY TO READ AND USE AND UNDERSTAND FEATURE of ternary operator and replacing it with less powerful but same looking elvis operator.( and stating that using if else for that is a better option)
Like why? if your goal is to make a shitty encoding language that makes everything shorter and most of the things optional, why remove the already efficient if else encoder?
God knows when this stupid language is going to stop my brain from getting blasted11 -
