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!!!2

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.

While getting a pro in Kotlin, I started using
when(condition) {
true -> doOneThing()
false -> {

What is your opinion on that?

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 -
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 -

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!

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!

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 -

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..

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.7 -

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

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.

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.

And what do we have? One mention somewhere in docs and an amazing test that 'explains' 'everything':

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 sleep10 -

Why the hell do languages like Kotlin (Java) and C# handle dates and datetimes so needlessly complicated?
There are multiple types with different implementations and concepts like local time or time zones represented by those types. Some of them have capabilities like serialization, some of them don’t.
Parsing and encoding is tied to the types.
Why? Take Swift as an example:
It has one single Date type (including time) which represents a point in time independent of any calendar, time zone, encoding or format.
There is a DateFormatter to parse from APIs from iso or timestamps or whatever and to format to UI as a string in any language (localization), for any region, in any format.
If you just want a container for the date time components themselves (which the concept of local date time seems to be in those languages), you can use the DateComponents type. If you are interested in dates from the perspective of a calendar, there is a Calendar type.
Everything makes sense and the different concepts are decoupled from each other as they should be.
Damn! My memory about C# is a bit hazy but Kotlin, I’m disappointed in you! Date handling is a horrible mess!
Ok, I guess I can blame it on Java and JVM.6 -

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!!!!!

I am starting to get a hang of kotlin at last.

Like static inner classes? Why would we even want them? Well the lady says am wrong, am wrong. -
Swift does some things really well, but then falls flat in others. Why is polymorphic JSON decoding/encoding such a pain?
In Kotlin, it's a breeze to support multiple object types.7 -
Where can I find a well paid junior Android Kotlin position?
I've been working in Switzerland for nearly 3 years now. I earned 72,000 (CHF) the first year, 78,000 the second year and now I've reached 86,400 at my current job. I quit this job and with the new job I'll be earning 96,000 after a 3 months trial period in which I'll earn the same as I earn now. I see a lot of Java jobs with Spring Boot and Angular but I'd really like to work with Android and Kotlin, I applied to Element.io and got rejected so I think I might need to apply as a junior Kotlin developer even though I have quite some experience.
I'm not sure where I could look for Kotlin jobs and if it's possible to not deviate too far from my current salary, I'm not sure which country and I'm not sure which platform I could use.
I've tried some stuff on LinkedIn and Indeed and others and I've tried in Switzerland, Israel and the US since I speak English and Hebrew natively and German fluently.
P.s. I know that you're all going to say that the expenses in Switzerland are higher, but I'm very frugal and this doesn't apply to me that much. I still earn a lot more than I would earn in Germany for example and I really don't want to earn 10,000 less...

There was more crap said, but I’ll spear you all the details. I just need to know if this is even remotely true. I’m sure it’s not, but he’s convinced it is. 🙄12 -
Kotlin
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.

Finally I introduce webpack to my kotlin beast... Say hello to react.. she is nice and pretty she will be best partner for you ..
I am developing my server side with kotlin and spring I needed some robust js for the fronted so I added react.. -
anyone done anything cool I can look at with a Kotlin Multiplatform project? just read about it and it looks really interesting.1
-
Holy shit, Kotlin does not have package-private?! I thought Kotlin was just a bad mix of JS syntax and Java... but not supporting an essential feature of the VM is on a whole another level of bad.

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.3

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 -
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 -
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

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 -
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))5 -
"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 -
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?8 -
Hey I am just curious, do you think is there any good reason to stick to Java now that Google officially supports kotlin?
Thanks1 -
Jetbrains shoot them self in the lag with taken fun as function keyword in kotlin #memesWillCome.
Don't blame me i love kotlin!
I even convinced my boss that we should continue in kotlin.2 -
1. More App-Development
2. Get more Clients
3. Learn something like Python or Kotlin
4. Bake a cake 🔥4 -
what kind of sorcery is this? how am i suppose to call this class( or whatever it is)'s functions?

hey guys
what's main difference between cross-platform and multi-platform?
and whats main difference between kotlin multiplatform and ReactNative?
i am familiar with both kotlin and NodeJS, What is your suggestion for build a app for ios and android?6 -
We are probably going to see even more kotlin. That's something, right? The dev future can't be all bleak ^^1
-
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

Why do people keep saying "kotlin is null safe, oh my god it's so safe, you don't have to worry about null's...". when all you have to do is add a question mark and BAM null-city!12

Plans:
Learn Rust and C++
Trying out the new K2 Compiler and probably ditching java for kotlin because kotlin is java
might invest in cryptocurrency
My friend almost tricked me into running an exe that deletes all your files all because he tried to decompile the js file i sent him as a joke ;-;6 -
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??

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 ...15 -
Hi!
Speaking of cross platform mobile development, what is your go-to tool and why? Kotlin KMM or flutter?
(I am excluding react native cause I already used it so I have a bit of a grasp of what the pro and cons may be)8 -
I've been learning android app development using kotlin/java for about 4 months, and i think i'm pretty good with kotlin/java, i've learned a lot of things related to android development, i've cloned netflix,spotify and made streaming apps with firebase as the backend, and I think I understand using firebase quite well because firebase itself is not difficult to use. Is it for my current skills that I deserve to work as a freelancer or do I still have to improve my skills?if it yes,give me an example of what kind of application I should do to improve my skills again!,I've read the android studio docs what to know and I've studied everything even though I sometimes forget how to make this/make that but I understand the logic quite well ok, please help7

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 -
So i have learn android studio course (kotlin) for the basic.I've been practicing for some things, like recyclerview, ViewModel, bottomsheet, fragment, nav view,Firebase auth, intent and some other basic stuff.right now I'm confused what to do next, if it continues I don't know what to learn next, I know there's still a lot of things to learn, it's just that I don't know what it is, I'm trying to find out what apps a beginner should make like me, but most of the suggestions are still far from my abilities, such as making a calculator. So can you give a little advice to beginners like me, thanks6

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

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 feel that it's better to develop in Kotlin, for android, as a beginner, given the recent announcement.
Any other suggestions?12 -
Okay so kotlin is basically just scala with some of the features removed and nobody can change my mind.1
-
Does anyone have experience with using Kotlin as a front end language? Seems to have excellent JS interop and I really don't want to deal with the garbage fire that is JS or TS 😬5

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 -
Java, Scala, Groovy, Kotlin or Closure? Which do you prefer?
If not Java from those above, can you give an example why?
I'm curious what you guys like. If you're not interested in Java, please stay away, it's not about C++ or any other fancy language.13 -
Hey, I have a question concerning the use of jpa annotations in a kotlin multiplatform project and how to organize shared data classes.
I already posted the question on stackoverflow: https://stackoverflow.com/questions...
I would appreciate every help :) -
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
-
Begin to hate Java, moving to kotlin soon . For android development at least with Jetpack compose. Java is deprecated in almost every API.
-
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. -
sort of an update on my midterm project read my last rant to catch up.
Progress so far has been absolutely phenomenal I have a sign up and login page, a profile page, home page, and can post to the app now in real time. for my first time using Kotlin I'm insanely surprised at what I've accomplished so far.1 -
!rant
Just learned that Kotlin has extension properties to go along with its extension functions. Anything else I'm missing?1 -
I have a little ask for you guys, If you need to start a Java project, Will you use kotlin or Just Java? I'm a little confused with this choice, so i need more visions19
-
Hey Kotlin users. Do you use Kotlin for Android, or for non-Android stuff? If both, then answer Android. I'm interested to see how many non Android Kotlin devs we have here.1

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 -
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).
-
All went crazy when Google announced that Android would support Kotlin ... but that is not new, and that takes a while being so

Lack of free resources for learning Kotlin for Android held me back a little. But I gotta continue.2
-
Anyone ever try Tomcat debugging in VS Code? Specifically with Kotlin? I'm starting to get real fed up with IntelliJ tbh... it keeps screwing up when I have a multi-project/module workspace.
-
Android Studio 3.2b4 once again regressed on "No tests found" bug for Kotlin projects.
I guess someone at big G decided to "comment out failing tests for now and come back to it before the release"
I feel like this rant should be riddled with profanity but at this point I'm not even angry just very disappointed 😥 -
Thought I'd give kotlin spring boot a shot. I assumed it would work out of the box like with java. It didn't. Apparently with jdk 17 I chose an incompatible version with the gradle version provided. Downgrade gradle. 'runApplication()' still marked with an error, which I cannot seem to solve. Answers from the internet are no solution.
But I can run the project ... but I cannot reach my dummy address, same with maven ... wtf, which part of rtfm did I miss? Wasn't kotlin supposed to be the better java?3 -
I tried Kotlin for a week. And I literally gave up. Hey, fellow Kotlin devs, what fun do you get in writing this short f**king syntactically unmatched java code!5

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. -
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 -
Hey guys,
I want to learn Android development with Kotlin. I have no prior experience with either technology. Where should I start?5 -
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 ?6
-
Seems like spring boot kotlin doesn't want to cooperate in any way. Tried to set up a backend with it, but it keeps showing an error regarding wrong jvm-target. The project runs nevertheless. I changed the maven settings according to the docs, but no change. Whatever, still runs. However a newly created "hello world" rest endpoint just doesn't work, even following a beginner tutorial. localhost:8080/hello ... error fallback page.
I really wanted to give kotlin a try. Doing the same with java, instantly working.
Fuck spring boot kotlin. Or fuck me for not knowing how to handle it.5 -
Does anyone here have experience with Kotlin?
I'm 100% JavaScript/web development for the moment but I consider trying to write some native Android apps earlier or later and heard some good things about Kotlin (language developed by the guys from IntelliJ afaik), which is supported natively by Android.
Soooo, how does it hold up? -
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.5
