            If anyone stumbles over this question:

            This is a known bug in the current Jetpack Compose build (1.0.0-beta08) which is supposed to be fixed with the next version.

            As a workaround I was able to do it the other way round, creating the SurfaceView as well as a ComposableView in XML and adding my content to the ComposableView.

            Using rememberCoroutineScope() vs LaunchedEffect
            Asked 2021-Jun-12 at 23:42
            Context

            In Jetpack compose, we have the option of using rememberCoroutineScope() as well as using the LaunchedEffect composable in order to use coroutines / run suspend functions (show snackbars etc).

            The convention I've adopted so far is to remember a single coroutine scope at the top of my compose tree, and pass it down via function arguments to places where it is needed. This vaguely seems like a good practice, but on the other hand it's adding extra noise to my function signatures.

            Questions
            1. Are there any reasons for preferring the use of LaunchedEffect over rememberCoroutineScope() inside composable functions?
            2. Is it worth the effort to only create / remember a coroutine scope once per compose tree, or should I just call rememberCoroutineScope() in each function where a coroutine is actually launched?
            ...

            ANSWER

            Answered 2021-Jun-12 at 23:42

            Leaving my understanding here:

            Question 1: LaunchedEffect should be used when you want that some action must be taken when your composable is first launched. For example, when you want to request some data from your ViewModel or run some sort of animation...
            rememberCoroutineScope on the other hand, is specific to store the Coroutine scope allowing the code to launch some suspend function... imho, the only relation between them is that you can also use a LaunchedEffect to launch a coroutine...

            Question 2: As you can see in the docs, rememberCoroutineScope will keep the reference of the coroutine's scope in a specific point of the composition. Therefore, if a given composable is removed from the recomposition, that coroutine will be cancelled automatically. For instance, you have the following composable calls A -> B -> C. If you remember the coroutine scope in C and it is removed from the composition, the coroutine is automatically cancelled. But if you remember from A, pass the scope through B and C, use this scope in C, and then C is removed, the coroutine will continue running (because it was remembered in A)...

            I'm currently playing around with the new Jetpack compose UI toolkit and I like it a lot. One thing I could not figure out is how to use stickyHeaders in a LazyColumn which is populated by the paging library. The non-paging example from the documentation is:

            I got it work by looking into the source code of the items function: You must not call stickyHeader within the items function. No need to modify the PagingData flow at all. Just use peek to get the next item without trigering a reload and then layout it:

            This appears to be a bug in Jetpack Compose, will probably need to wait for an update on the Jetpack libraries to address it.

            As a possible workaround, you could instantiate the viewmodel in your activity and pass it to your composable function

            What is the difference between using Safe Args for screen transitions and not using them?
            Asked 2021-Jun-11 at 19:16

            Safe Args

            I was referencing the JetPack Navigation Component related documentation to create a bottom navigation for screen transitions.

            But in that link it says:

            • The recommended way to navigate between destinations is to use the Safe Args Gradle plugin.
            • Safe Args is recommended both for navigating as well as passing data between destinations.

            After seeing this, I have a few questions.

            Is there a performance difference between just using the navaigation component and using safe args?

            Of course, safe args even has the ability to pass data between screens. But apart from this, is there any difference only in terms of screen transitions (navigation)?

            ...

            ANSWER

            Answered 2021-Jun-11 at 19:16

            Safe Args just generates code that you can write yourself, following the guide to navigating by ID and manually passing a Bundle of arguments - it has no effect on the performance of your app at runtime or how screen transitions work.
