Hi all, I have question about “Managed Publishing” In google play, I wanted to fully automate release process but it can’t find anything about this in Google Play Developer API. Do you know of there is possibility to use managed publishing from API ?

Hi all, I’ve switched to Android Studio Preview to use Jetpack Compose but I’m having problems with UI Testing in Espresso. On Google I couldn’t find anything, I think it’s some sort of bug of the AGP 7.0. The error refers to androidx.test.internal.platform.tracker.UsageTracker. NoClassDefFoundException

I use Room primarily to convert SQL queries to

Flow

. However, I prefer to work directly with the support library APIs. How to convert a generic query to a

Flow

(either using a 3rd party library or building from scratch)?

hello. does any1 know the name of the gradle task to run when generating the viewbinding classes ?

Whats the easiest way to achieve a fully transparent status bar? currently it looks like this: (this is inside a fragment which hosts a map fragment)

Hi everyone! I’m facing a weird issue, we used to use

kotlinx.synthetic

, (yeah! but is deprecated now), hence we start to migrate to viewBinding (honestly much better), but I’m facing next issue. I have a fragment such contains a MapFragment itself like this..

<androidx.cardview.widget.CardView
    android:visibility="visible"
    .....
    app:layout_constraintTop_toTopOf="parent">

    <fragment
        android:id="@+id/onTheWayMap"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</androidx.cardview.widget.CardView>

Before with

kotlinx.syntheti

we only invoke following lines:

override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? = inflater.inflate(R.layout.a_fragment, container, false)


val mapFragment = childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment?
        mapFragment?.getMapAsync { //mapFragments never null
            googleMap = it
            ...

Since we’re migrating to

viewBinding

, keeping same code above, mapFragment always is null, anyone here had faced same issue?, do you guys know how to fixed?, what can be wrong?

private val binding by lazy {
        FragmentOnTheWayBinding.inflate(LayoutInflater.from(context))
    }
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? = binding.root


val mapFragment = childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment?
        mapFragment?.getMapAsync { //always null
            googleMap = it

Hello Can any one help me to convert the bluetooth remove bond java code to Kotlin?

Hi everyone, I'm currently stuck in a "simple" use case using Hilt: I want a Retrofit service singleton, which takes an OkHttpClient. The OkHttpClient has an interceptor, which uses the Retrofit service singleton (to make a certain request inside the interceptor) The problem is: -> The OkHttpClient takes a Retrofit as argument -> The Retrofit takes an OkHttpClient as argument Cheers

val bookmarks = repository.getAllBookmarkedArticles()
        .stateIn(viewModelScope, SharingStarted.Lazily, emptyList())

Is it bad to initialize with

emptyList()

? This is data from Room, hence it has no loading state

I've inherited an Android kotlin app, and am scrambling up the learning curve (done quite a bit of iOS). I need to make one simple GET request, not on the main thread of course. Is there a simple/idiomatic/not-too-bleeding-edge/lightweight/reliable go to for this kind of thing? I found okhttp and will probably use it unless there's a better suggestion. it looks pretty well supported, but it is originally a java library, and i wondered if there was something more kotlin-esque

Hey guys im getting this really weird error on android for my robotics team (FTC specifically) I am trying to call the invoke operator from the companion object in

override val keys: Keys get() = GamePadKeysOld(gamepad = gamepad)

and it gives me a

Sealed types cannot be instantiated

error when building the android app I tried a small test case in a kotlin playground ( https://pl.kotl.in/8VWvKtOqm ) and set both versions to 1.4.30 and in the playground the error does not pop up and successfully runs Is there a reason for this and a way to fix? (I would like to keep it as an invoke call though just changing the function name is the solution I am currently using) Thanks in advance!

Duration.toMinutespart

is very useful in Java . Why Kotlin does not have such of this useful function ???

Actually, I want to convert seconds Int to

Hi everyone, quick question for which I can't find the answer on Google: When using Navigation API, and SafeArgs:

val args: SomeFragmentArgs by navArgs()

Does the

args

field keep its values after the activity gets killed by the system and recreated? In other words: does the Bundle sent to the Fragment survive? Cheers

I have 3 fragments in my bottom nav and their ViewModels stay in memory to preserve their state (the fragments are only detached, not removed). Is it okay that these ViewModels keep getting database updates even if the fragment is not active? I'm using the

stateIn

operator so that a Flow that starts fetching new data doesn't cancel when we switch screens. But after that remote fetch is done, the Flow will keep emitting cached data from the DB (which could get updated indirectly from another screen) even if the fragment is not active.

Hi 👋 , I was wondering if anyone has experience with Server-driven theming in Android apps? I want to be able to fetch the Primary/Secondary colours from the API and apply to the application.. The usecase is for theming a white-label app 🤔 …

Hi everyone, imagining this senario: -> I have a table in Room Database called "UserApplicationPreferences", where I keep configuration options for each user, and a loggedIn boolean; -> When a user enters the App, a query will be executed to find out if there is any UserApplicationPreferences with the flag loggedIn. -> If (or when) there is a loggedIn user, I want the corresponding UserApplicationPreferences instance to be synchronously available, everywhere in the app. -> Whenever the user changes their preferences, the saved instance should change (automatically, preferably). I was thinking the saved instance could be just the Flow returned in the Dao, but then to get its value I need to call collect() which is asynchronous (makes sense). Is there some way to like always be collecting from the flow and updating the instance (which will be in the Repository) or something like that? My goal is to: -> Have synchronous access to the UserApplicationPreferences (as I would when using SharedPreferences) -> Minimize queries to database (in-memory caching the up-to-date UserApplicationPreferences instead of running the query to get the up-to-date UserApplicationPreferences each time) This is working as I intended. There is no way this is good practice, right?...

@Singleton
class UserApplicationPreferencesRepository @Inject constructor(
    private val dao: UserApplicationPreferencesDao,
){
    var loggedInUserPreferences: UserApplicationPreferences? = null
        private set

    init {
        CoroutineScope(SupervisorJob() + <http://Dispatchers.IO|Dispatchers.IO>).launch {
            dao.getLoggedInFlow().collect {
                loggedInUserPreferences = it
            }
        }
    }
}

Hi everybody ! I've got this build.gradle from a React Native project. It worked before I upgrade inside to latest Gradle version Android Studio. (Android Gradle Plugin)

Hey guys, I'm trying to understand styles in android. This is the following style I created for my button.

<style name="OrangeButtonPrimary">
        <item name="android:textColor">@color/white</item>
        <item name="cornerRadius">8dp</item>
        <item name="backgroundColor">#FC7E2F</item>
        <item name="android:textAllCaps">true</item>
    </style>

However, when I add the style to my button nothing happens. I am therefor wondering whether I did something wrong or not?

Hey everyone, so there's this "new" way to apply plugins in Gradle right?

plugins {
    id "org.jetbrains.kotlin.android" version "$kotlin_version"
}

I love the fact that it doesn't require me to change the classpath in project-level build.gradle ...But, does it work for every plugin? If it does, how would I do this?

id "androidx.navigation.safeargs.kotlin" version "2.3.3"

(Plugin [id: 'androidx.navigation.safeargs.kotlin', version: '2.3.3'] was not found in any of the following sources:)
