Solution 1:

You can detect currently foreground application with ActivityManager.getRunningAppProcesses call. It will return a list of RunningAppProcessInfo records. To determine which application is on foreground check RunningAppProcessInfo.importance field for equality to RunningAppProcessInfo.IMPORTANCE_FOREGROUND.
