Hello everyone, how to know which parts ( libs/resources/modules etc) increase app size? Thanks

Hi everyone, How can I create a custom RadioGroup like this one , I was able to change the check and uncheck drawable but I having trouble creating the clipped background

can someone help me with this please I keep error about failed to complied value files

Is there any reason I shouldn’t use GlobalScope in an Application scoped LifecycleObserver?

hi super dumb question but how can i view a list of versions for a given gradle dependency? i am aware of android studio’s built in support but it only works for some dependencies and not others. is there some command line like

gradle info com.googlecode.libphonenumber:libphonenumber

?

However, I’m seeing an error with LiveData. Basically, saying LiveData is abstract (which makes sense) and

Initializer is not allowed here because this property has no backing field

Shorter:

val word: Live<String> = _word

Are there drawbacks to this approach? I want to do something similar. I have a

LiveData

and I want to make an extension function that transforms it to

Flow

(since I am using

Flow

all over the App) https://gist.github.com/chibatching/9fdd23d0d41980980a1c1af2e1803e01

With

DataStore

if I want to access a value synchronously the documentation says to use

runBlocking

like so

runBlocking { dataStore.data.first() }

Would I be able to instead use something like

withContext(<http://Dispatchers.IO|Dispatchers.IO>) { dataStore.data.first() }

What is the difference between those two approaches?

Should error message in my UI be sticky (shown again on orientation change) or one-off events? Is it correct to say that one-off actions (i.e. suspending functions) should show one-off error messages (like a failed login attempt) and failed Flows (like a list not being able to load because of insufficient permissions) should show a sticky error message?

Using AS Arctic Fox with Kotlin 1.4.20 and all my collection methods have turned red, though it still builds. Anybody else see this?

Hi, I wrap my head around a problem. I want to build a data class in relation to specific conditions. For instance:

data class Test(val test1: Int, val test2: Int)

This would be the base and if a specific condition is satisfied:

data class Test(val test1: Int, val test2: Int, val test3: Int)

I could create 2 separate data classes but then I always have to pass both and I'd like to deal only with one data class. Does someone has an idea?

How to pass data from a fragment hosting

FragmentContainerView

to its child fragments (which are part of the navigation graph used by FragmentContainerView)

Is there a way to contribute to the Android developer documentation pages? E.g. open issues or PRs? I think that this page could use a lot of small improvements because it misses certain things: https://developer.android.com/kotlin/flow/stateflow-and-sharedflow

I see that neither Corbind nor FlowBinding expose View's state as

StateFlow

. Does it make sense to do so? Is there another library that is doing that?

What should we use for long running tasks that should survive process deaths or app restarts?

CoroutineWorker

with

foregroundInfo

isn't working in my case. I've opened up a websocket connection and want to listen for messages in background forever.

How can I avoid font override by system? For example: if a user set a custom font through settings, I don’t want my app to use that custom font but instead use sans-serif. I tried adding fontFamily to styles.xml but it didn’t help.

i need good tutorials of kotlin mvvm with okhttp without databinding. any help would be appreciated

what does it mean when I get just 1 JSON object in my response and doing

or

find

on it produces exception index out of bounds?

hey guys how feasible is it to create a lottie splash screen. Setting up the theme is easy ..reference the drawable but getting the animation to start as a lottieview is what i’m thinking about

are there any performance benefits of replacing livedata with flows? i’m assuming the difference is livedata is closely bound to android arch?

Just looking for ideas. Have lot of data that needs to be inputted by the user for addition of something, so what is the best approach around it? One is to divide it into steps or parts, but how does one maintain the state of data on previous screens then before moving to next one, so that if a user traverses back, their data remains safe.

Hi There, Can we used compose on production?

Can StateFlows somehow be used to communicate between Fragments? Share data somehow via it? Also, is it recommended to do so?

I am looking for a tutorial showing how to handle multiple error types from retrofit. I'm currently using "Either" style types (one for Successs & Error each) but our APIs seems to have different json formats for different errors so I need a way to handle them in form of Sealed Class type. I found ZachSweers'

moshi-sealed

extension might help in this scenario but I'm afraid I won't be having any "type" parameter in the json which is required for

moshi-sealed

. Any tutorial hinting different approaches would also work.

Hi kotliers and a huge thanks in advance for reading my message! Question to following case: • Is it possible to eliminate

reified

in this mehod? I want to have a method which loads a value from the firebase database and the value needs to be properly typed when returned

class OnlinePersistence { 
    suspend inline fun <reified T> loadValue(path: OnlinePersistencePath, default: T) =
            withContext(IO) {
                suspendCancellableCoroutine<T> { continuation ->
                    FirebaseDatabase
                            .getInstance()
                            .getReference(path.rawPath)
                            .addListenerForSingleValueEvent(object : ValueEventListener {
                                override fun onDataChange(snapshot: DataSnapshot) {
                                    if(continuation.isActive) {
                                        val value = snapshot.getValue<T>()

                                        if(value != null) {
                                            continuation.resume(value)
                                        } else {
                                            continuation.resume(default)
                                        }
                                    }
                                }

                                override fun onCancelled(error: DatabaseError) {
                                    if(continuation.isActive) {
                                        continuation.resume(default)
                                    }
                                }
                            })
                }
            }
}

All well and good now, but when I extract

FirebaseDatabase.getInstance()

into the constructor I cannot make it private like it should be. (Since the method is inline because of reified)

can I ask questions related to android studio issues here?
