Jetpack Compose OverlayService. You have to have all the correct permissions granted and in your manifest, but if you do, this this will show a green box with "Hello" in it!

give permission in manifest file::

permission android:name="android.permission.SYSTEM_ALERT_WINDOW"

in MainActivity code is ::

class MainActivity : ComponentActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    if (!Settings.canDrawOverlays(this)) {
        val intent = Intent(
            Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
            Uri.parse("package:$packageName")
        )
        startActivityForResult(intent, 101)
    }
    setContent {

        TikDownloaderTheme {
            // A surface container using the 'background' color from the theme
            Surface(
                modifier = Modifier.fillMaxSize(),
                color = MaterialTheme.colorScheme.background
            ) {
                val context = LocalContext.current
                val windowManager = context.getSystemService(Context.WINDOW_SERVICE) as WindowManager
                AddFloatingButtonOverlay(windowManager)

            }
        }
    }
}

}

@composable fun AddFloatingButtonOverlay(windowManager: WindowManager) { val context = LocalContext.current val composeView = remember { ComposeView(context).apply { setContent { Box { FloatingButton(onClick = { }) } } } }

// Set layout parameters for the floating button
val params = WindowManager.LayoutParams(
    WindowManager.LayoutParams.WRAP_CONTENT,
    WindowManager.LayoutParams.WRAP_CONTENT,
    WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
    WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
    android.graphics.PixelFormat.TRANSLUCENT
)

// Set the position of the floating button on the screen
params.x = 100 // Set the X position
params.y = 100 // Set the Y position
composeView.setViewTreeLifecycleOwner(LocalLifecycleOwner.current)
composeView.setViewTreeSavedStateRegistryOwner(LocalSavedStateRegistryOwner.current)

windowManager.addView(composeView, params)

}

@composable fun FloatingButton(onClick: () -> Unit) { FloatingActionButton( onClick = onClick, modifier = androidx.compose.ui.Modifier.padding(16.dp) ) { Text(text = "Floating Overlay") } }

This solution works for me, thanks a lot. Saved me two days.
