How to check android application in background or not?

Check if application in background or not snippet

public static boolean isApplicationInBackground(Context context) {
        ActivityManager am = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);
        List taskList = am.getRunningTasks(1);
        if (taskList != null && !taskList.isEmpty()) {
            ComponentName topActivity = taskList.get(0).topActivity;
            if (topActivity != null && !topActivity.getPackageName().equals(context.getPackageName())) {
                return true;
            }
        }
        return false;
} 

whether the application is in the background we need to define permission android.permission.GET_TASKS in Manifest.xml


This function will return true if the application in the background otherwise it will return false.
