    @Override    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        
        if(Intent.ACTION_USER_FOREGROUND.equals(action)){
            // Todo: do something when switch in the user
        } else if(Intent.ACTION_USER_BACKGROUND.equals(action)){
            // Todo: do something when switch out the user
        }
    }
