Android 監聽開機廣播啟動服務 動態注冊時間變化監聽廣播

開機廣播權限

public class BootedReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		context.startService(new Intent(context, TimeService.class));
	}

}

//服務 用於  注冊 監聽時間變化、設置的廣播   時間變化廣播只能動態注冊

		registerReceiver(mTickReceiver, mFilter); 
	}
