I developed an application in which I upload my YouTube channel to webview and it works just fine as expected. I can play videos on a small screen, as well as in full screen.
But the problem is that I put the application in the background while the video plays in full screen and causes the foreground application to crash. I saw the crash log, but it shows nothing from my code. I don’t understand what is the cause of the accident. It shows a NullPointerException, but where it came is a mystery.

The application does not crash if I place the application in the background while the video is playing only on a small screen.
