I have a simple

Flow

wrapper around

LiveData

and I have a problem, because it closes (

invokeOnClose

is called) immediately after first value is emitted by

Observer

Copy code

fun <T> LiveData<T>.asFlow(): Flow<T> = channelFlow {
    value?.let { offer(it) }
    val observer = Observer<T> { t -> t?.let(this::offer) }
    observeForever(observer)
    invokeOnClose {
        removeObserver(observer)
    }
}

To be sure my

CoroutineScope

is not causing this cancellation, I run this also in

GlobalScope

and the behaviour was the same. How can I see what is causing cancellation? I analysed stack trace, but I didn’t see anything interesting there.

Hey, I have a login fun and I want it to wait for .signInWithEmail.. to finish and then based on it's result, to do something and return a TaskResult. Now the problem is that the onCompleteListener doesn't happen before the last return. Is there a way to wait for its completion? I looked into .async and .await but didn't find any useful docs. If anyone can point me in the right direction it would be appreciated. (this is in my RemoteDataSource and the Repository calls the Login fun)

Copy code

fun Login(email: String, password: String): TaskResult {
         var taskResult = TaskResult.LOADING

          firebaseAuth.signInWithEmailAndPassword(email,password).addOnCompleteListener { 
              if(it.isSuccessful){
                  taskResult = TaskResult.SUCCESS
              }
          }

         return taskResult // THIS TRIGGERS BEFORE THE ONCOMPLETELISTENER, so I always get TaskResult.Loading back
     }

I am also looking to run this in a coroutine

Does anyone here have had this problem with

kapt

and

Dagger

in multi-module projects ?

Copy code

> Task :app:kaptDebugKotlin FAILED
e: error: cannot access HttpClientEngine
  class file for io.ktor.client.engine.HttpClientEngine not found
  Consult the following stack trace for details.
  com.sun.tools.javac.code.Symbol$CompletionFailure: class file for io.ktor.client.engine.HttpClientEngine not found

It seems to occur because a dependency (Ktor-client in this case) is defined as

implementation

in a different Gradle module (feature) than the one the component is created (app).

Is it ok to use

GlobalScope

for coroutines that need to be tied to the

Application

? There doesn't seem to be a

lifecycleScope

for it... or is it better to create a

CoroutineScope

and cancel it somewhere in the

Application

Hi! A coroutine causes a FATAL EXCEPTION but does not give any stack trace or clue about what coroutine it is:

Copy code

01-14 11:40:10.990  4508  4508 E AndroidRuntime: FATAL EXCEPTION: main @coroutine#4
01-14 11:40:10.990  4508  4508 E AndroidRuntime: Process: com.readly.client, PID: 4508

I am running with

Copy code

System.setProperty(kotlinx.coroutines.DebugKt.DEBUG_PROPERTY_NAME, kotlinx.coroutines.DebugKt.DEBUG_PROPERTY_VALUE_ON)

but still get the above silent fail. What is the best way to find what coroutine this is? (Without using “brute force”)

Kinda dumb question, but isn't there an option to make the Edit Text required (must be inputted). I figured it would be available in the layout designer but it's not. I understand that it can be done programmatically but still. This seems like a basic function, I might've missed something, if not is there a feature request or a library or something? Thanks in advance! did google no results related to what i wrote above.

Good morning everyone. Do you use kotlin dsl for gradle already? Is where any usecase, except

I want to try the new thing

, why I want to switch to kotlin dsl for build files. I'm asking this, because I'm seeing a bunch of minuses with the IDE support (Android Studio in particular). Will start with pros though... DSL and kotlin build src will give an ability to nicely handle dependencies and it is working like a charm and looks clean etc. With only one minus, that ruins everything. The IDE suggestions for libraries updates are not detected anymore and not possible. Same for

flavor dimentions

if they are defined in kotlin object constans, the IDE shows warning, that no dimention are being added to any of the flavors. The build time is also increased for about a minute (with normal 6 minutes build time, it is now about 7 minutes). Does anyone knows what are the plans for support kotlin DSL from the Android Studio side? (just for reference, everything I descibed was tested with latest Android Studio 4.0 canary 😎

Hi all, do you have any recommendation how to handle authentication loss in background (e.g. when receiving an 401 from a call in background). I am tending to invalidate the authentication in my repository, make my view models listen to the change and navigate to the login screen. But I am in doubt if I should observe repository members at all? Does anybody have a rough hint on how to do this with AAC?

Hi guys, have you ever faced this problem before? I've got this error as the attached image, the red rectangle is the file under generated folder, the blue rectangle is my strings file. I don't understand why Android Studio(AS) autogenerate a "google_api_key" even when I deleted my own key then rebuild the project. But if I re-add my own key then AS throw an error as you can see. Thanks in advance about your help.
