Good Morning all. I am having a cosmetic issue with camera media3 compose (this might exist in the xml version too). If i play a video, and let the video run it's full length. Then i background the app, then foreground again, it's showing a black background over the player surface. However, when i pause the video in the middle and do the same, it shows the frame where it was paused.

I would have expected that in the first case, it would just render the last frame when it came back from the background instead of a black screen.

val player = remember {
    ExoPlayer.Builder(context).build().apply {
        setMediaItem(
            MediaItem.fromUri(url)
        )
        prepare()
    }
}

PlayerSurface(
    player = player,
    modifier = sizeModifier
)

If you're using SurfaceView behind the scenes, try switching to TextureView, which retains the surface in the background.

[Nitesh Singh]

In your Composable, if you're using a custom PlayerSurface, ensure it's using TextureView

[Nitesh Singh]

AndroidView(
factory = {
PlayerView(it).apply {
player = exoPlayer
useTextureView = true
}
},
modifier = Modifier.fillMaxSize()
)

Thanks.

lifecycleOwner.lifecycle.addObserver(observer)
