1、客户端锁屏状态，无法发送心跳包

解决方案：使用电源锁

客户端：NotificationService

增加属性:

/**
	 * 设备电源锁。
	 */
	private PowerManager.WakeLock mWakeLock;

/**
	 * 申请设备电源锁
	 */
	private final void acquireWakeLock() {
		if (mWakeLock == null) {
			PowerManager pm = (PowerManager) this.getSystemService(Context.POWER_SERVICE);
			mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, this.getPackageName());
		}
		if (mWakeLock != null) {
			mWakeLock.acquire();
			Log.d(LOGTAG, "mWakeLock.acquire()");
		}
	}

	/**
	 * 释放设备电源锁
	 */
	private final void releaseWakeLock() {
		Log.d(LOGTAG, "releaseWakeLock");
		if (mWakeLock != null) {
			mWakeLock.release();
			mWakeLock = null;
		}
	}

@Override
	public void onStart(Intent intent, int startId) {
		Log.d(LOGTAG, "onStart()...");
		acquireWakeLock();
	}

private void stop() {
		Log.d(LOGTAG, "stop()...");
		unregisterNotificationReceiver();
		unregisterConnectivityReceiver();
		xmppManager.disconnect();
		executorService.shutdown();
		releaseWakeLock();
	}
