Hi!
I have a mixed view-based and compose project. I set the composable in the activity's onCreate.
In the Composable I start a `LaunchedEffect`, which is polling a connected device every 5 seconds. When I put the app in the background and later bring back in the foreground, the `LaunchedEffect` starts again, but as far as I can see, the original is also still running.
```LaunchedEffect(Unit) {
    while (true) {
        viewModel.doSomething()
        delay(5.seconds)
    }
}```
How can I prevent the polling duplicating itself in this case?

Move the polling into the viewmodel and cancel it when ithe viewmodel is cleared.

If you want to keep it on the UI layer - what’s anyway a bad idea - I guess if you pass the viemodel as a key to the LaunchedEffect it should also cancel the previous one.
