Can someone advise how to avoid having the below ANR reports in Google Play Console:
Broadcast of Intent { act=android.intent.action.SCREEN_OFF flg=0x50000010 launchParam=MultiScreenLaunchParams { mDisplayId=0 mFlags=0 } (has extras) }

I am not sure what causes these, I can only assume that they might be caused by a lengthy save game operation which I execute inside my Game.Stopped event handler:
public void SaveGame() { if (g != null && g.IsRunning) { try { CreateDirectoryForFilePath(_savedGameFilePath); if (g.GameType != 0) { using (var fs = File.Open(_savedGameFilePath, FileMode.Create)) { g.SaveGame(fs, saveDebugInfo: true); } } else { File.Copy(_newGameFilePath, _savedGameFilePath, true); } } catch (Exception e) { System.Diagnostics.Debug.WriteLine(string.Format("Cannot save game\n{0}", e.Message)); } } }
Can someone confirm what is the cause and/or suggest a workaround? I think that calling SaveGame on a separate thread is probably not the right thing to do given that my application is about to be paused, right? Any help is greatly appreciated!
