Why is the “project level dictionary” called jay.xml? Surely this should be a VCS-shared file, common across everyone working on the project?

Hello all, I'm new to kotlin and have 6+ years of experience in Android(Java). Need some begin with tips, thanks in advance.

Hallo, does any of you use currently any redux implementation in Android? is there any stable usable library? What are the experiences so far with redux in Android for you? I have used redux before with Angular and it was great. Now I'm trying to decide between using redux or Android Architecture Components with MVVM. Regards

Why does the access of result annotated with

android.annotations.Nullable

generate a mere warning instead of an error?

Is there anything you can do to disable this false positive lint check when using

use

from KTX, but still have it if you actually don’t recycle the

TypedArray

? (Not this instance of course, but any future instances)

I was considering to scope an extension to an annotated type similar to

inline val @receiver:ColorInt Int.alpha get() = (this shr 24) and 0xff

from KTX, but unfortunately the extension is visible to any

Int

. Is it the expected behavior or a known issue?

Maybe you should open an issue for this (or maybe there’s one)

Hi folks, hail mary play here — getting the following error adding a dependency on a MPP android artifact. It looks like https://github.com/Kotlin/kotlinx.coroutines/issues/510 except this is just a bare bones pet project — not using coroutines.

Hello guys I have a problem compiling a module on release flavour :

Cannot find a version of 'org.jetbrains.kotlin:kotlin-stdlib-jdk7' that satisfies the version constraints: 
   Dependency path 'mymodule:unspecified' --> 'org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.11' --> 'org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.11'
   Dependency path 'mymodule:unspecified' --> 'io.realm:realm-android-kotlin-extensions:5.9.0' --> 'org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.2.50'
   Constraint path 'mymodule:unspecified' --> 'org.jetbrains.kotlin:kotlin-stdlib-jdk7' strictly '1.2.50' because of the following reason: debugRuntimeClasspath uses version 1.2.50

What is the common thought process on Java vs Kotlin? If you are new to programming and want to get into Android, is it ok to learn just Kotlin or do I have to learn Java first and then learn Kotlin after I learn Java? (if I'm looking to land a job not just create my own app)

Is this actually a thing?

How do you unit test coroutines that use

withContext(<http://Dispatchers.IO|Dispatchers.IO>)

, is there a way to replace

<http://Dispatchers.IO|Dispatchers.IO>

to use the main thread in unit tests? Or do I have to pass a dispatcher with DI to replace in tests?

Hello,Please can you help me ? I am beginner. Where can be a bug ? /Kotlin 1.3.21,AS 3.5 Canary 4 / I tried to change Gradle version current 5.2.1 and Invalidate Caches/Restart did not help. Thanks https://hastebin.com/zeyovujumu.shell https://hastebin.com/umowehuqew.xml https://hastebin.com/gixuvicabe.cpp

Does anyone know if there is a place to submit feature requests for ktx. I have been thinking about

Parcel.readSparseArray

. It returns

SparseArray

without any generic parameter and I am not aware of a way to read it with the generic parameter. It should be fairly easy to reify that one to do a cast for you. I know that this is not something that is super hard to do yourself but it feels like a hack every time i need to suppress the unchecked cast warning.

Don't know if here is the correct thread to ask, but anyway.... for a new project (which will be 100% kotlin) we (team) are discussing regarding dependency injection framework and which one to use, if any... the more I'm looking into that, the more I don't see any reason to use it, because kotlin supports default parameter (constructor or method). Even looking into the description of Koin or Kodein I don't see any text regarding why, benefit of using DI framework. Can someone with more experience (I never tried any) tell me some benefits of using one please?

Can any one suggest image tagging library in Android ?

IntelliJ doesn’t find a R.java file, Android Studio does but does not tell me where it is, all I can find on SO is things about a root

gen

folder, I don’t have that... Any idea why I don’t have a R file? I’ve been stuck on this for hours now. The build works, the app works, IDEA just keeps telling me R is not found and removing the imports every time I optimize imports

Guys, could you please share your experience of writing Espresso test for LoginActivity with

idling resource

? Probably someone can suggest good tutorial how to implement this case? I have my own implementation, but it works time to time.. I’ve missed smthg..

Has anyone ever used Moshi as a converter for retrofit. I am having some problems with Array List. Exception is thrown because I don't have an adapter for array list. I don't quite understand what I am supposed to do here. Retrofit version 2.5.0.

Hi, how in Android Studio I can generate implementation of superclass members with(!) automatically delegating to specific field of the class? I want implement simple delegation pattern, but don't want write it manually. Maybe some plugin for Android Studio? Ask here because initially I decided use Kotlin and its implementation by delegation but then I had to refuse it 🙂

hey there , how do you access any type inside your adapter eg:

val list:Any

then how do i access the value of

Any

How do you guys handle coroutine scopes in Fragments? I find with most of my tasks that cancelling on pause is the most logical choice, as they are usually started when the view is created. But if I cancel the scope, I can't re-launch tasks on it upon resuming.

In my app i want to implement feature to get App rating from users. But as per my need App rating should be asked in case of major app version upgrade. It should not be triggered for minor version upgrade. For example : Case 1: If previous version is 1.0 and new launched App version is 2.0 then it app should prompt for App rating. Case 2: If previous version is 1.0 and new launched version is 1.5 then it should not prompt for app rating. Just wondering is there any ready to use solution available for this implementation ?

Hello, in my app I’m using Retrofit2+Moshi with KotlinJsonAdapterFactory, I have some case when I do want to send NULL value of some field, any ideas? (related to Moshi configuration)

I learnt basic Java and migrated directly to kotlin(new comer) but the problem comes most documentation, libraries and snippets are almost written in Java so it's pain and I know kotlin to Java converter exists , i sometimes think of going back to Java can some help me out regarding the issue

If I combine all Java classes in one single Java file, will that work?

Why the former works with the type inference when the latter doesn’t?
