IllegalArgumentException from closing service that draws on other apps

Question

I am writing an android app that runs a service in the background that makes use of the OVERLAY_PERMISSION to draw on other apps. It starts with an intent from a button on my main activity. So far, so good.

In my service, in my onDestroy(), I have a if (myView != null) windowManager.removeView(myView);. And when I call stopService from the activity, I get an error, saying:

java.lang.RuntimeException: Unable to stop service com.supernovaapps.cameralevel.LevelService@ed1633f: java.lang.IllegalArgumentException: View=android.widget.AbsoluteLayout{94fb155 V.E...... ......I. 0,0-0,0} not attached to window manager

I am only able to close the service if I comment out that line. However, if I do that, the view remains on the screen even after the service is closed, which is not what I want.

What is the correct way to close the service and detach the view?

looks like you passed a different view to windowManager than what was added to it before. — Nishant Srivastava, Dec 21 '15 at 01:34
@Radix sorry, adding full stacktrace. Also, its the same view, but I removed and added it a bunch of times in the middle. That shouldn't cause any issues, right? — Maltysen, Dec 21 '15 at 01:36
It doesn't sound right to be operating directly on views from services - the lifecycle isn't really designed to cope with it. Maybe a pub-sub/event bus/callback to the view controller..? — saywhatnow, Dec 21 '15 at 01:39
@Radix nvm, you were right about it being a different view. Thanks so much. Put it as an answer and I'll accept. — Maltysen, Dec 21 '15 at 01:40

@saywhatnow I'm using sensor data to update the view from the service. — Maltysen, Dec 21 '15 at 01:41

Looks like you passed a different view to windowManager than what was added to it before. Just pass it the right view and it would work.
