Is there a way to get a callback when an AndroidView is being detached before the view is detached from the window? I’m trying to get a bitmap of the last frame played in ExoPlayer before the view is removed.

should be able to use a standard attach state change listener, e.g.

AndroidView(
    factory = { context ->
        View(context).apply {
            addOnAttachStateChangeListener(
                object : View.OnAttachStateChangeListener {
                    override fun onViewAttachedToWindow(v: View?) {}

                    override fun onViewDetachedFromWindow(v: View?) {
                        TODO("Not yet implemented")
                    }
                }
            )
        }
    }
)

That is called after releaseSurfaceTexture is called in the TextureView

So it’s too late to get the bitmap

ah, I'm not familiar enough with exoplayer's expected lifecycle for that then. You should be able to use the same basic idea with a more appropriate exoplayer callback
