我创建了一个ActivityMonitorService，它扩展了AccessibilityService以捕获TYPE_WINDOW_STATE_CHANGED事件。但是当我强行关闭我的应用程序时，手机会一直重启。 onUnbind（）是在主要活动onDestroy（）时调用的，但每次手机重启后，ActivityMonitorService都会重启并因某些原因重启我的手机。请给我一些建议。

}

super.onRebind(intent);
Log.i(LOG_TAG, "--------onRebind--------");

super.onCreate();
Log.i(LOG_TAG, "--------onCreate--------");
