在做一个项目， 有一台android需要实时接受其它客户端的udp数据包(包括在锁屏的状态下)， 我使用了mina框架， 在未锁屏的时候， 是能够正常的接受到数据包的， 但是一旦锁屏了就再也无法接受到数据包了， 直到唤醒屏幕。
以下是我service中的代码：

public class ListenerService extends Service { private PowerManager.WakeLock mWakeLock; private MINAServer server; public static long lastMsgReceived = System.currentTimeMillis(); @Override public IBinder onBind(Intent intent) { return null; } @Override public void onCreate() { super.onCreate(); Log.i("log_info", "ListenerService onCreate"); try { server = new MINAServer(); } catch (IOException e) { e.printStackTrace(); } acquireWakeLock(); } @Override public int onStartCommand(Intent intent, int flags, int startId) { Log.i("log_info", "ListenerService onStartCommand"); // 启动一个定时器， 每隔32秒检测一次： lastMsgReceived 减去 当前时间。 Timer timer = new Timer(); timer.schedule(new RecordConnTimes(), 0, 32 * 1000); return super.onStartCommand(intent, flags, startId); } private void acquireWakeLock() { if (null == mWakeLock) { PowerManager pm = (PowerManager)this.getSystemService(Context.POWER_SERVICE); mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK| PowerManager.ON_AFTER_RELEASE,""); if (null != mWakeLock) { mWakeLock.acquire(); } } } @Override public void onDestroy() { if (null != mWakeLock) { mWakeLock.release(); mWakeLock = null; } super.onDestroy(); } private class RecordConnTimes extends TimerTask { @Override public void run() { Log.i("log_info", "RecordConnTimes run"); long currentTime = System.currentTimeMillis(); // 如果连续3次都没有接收到其它android端的广播， 则输出没有广播。 if (96 * 1000 <= currentTime - lastMsgReceived) { Log.i("log_info", "大于等于3次没有接收到广播"); } else { Message msg = new Message(); Bundle bundle = new Bundle(); Log.i("log_info", "小于3次没有接收到广播！！！"); } } } }

下面是mina handler的messageReceived方法：

public void messageReceived(IoSession session, Object message) throws Exception { SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss "); Date curDate = new Date(System.currentTimeMillis()); //获取当前时间 if (message instanceof IoBuffer) { IoBuffer buffer = (IoBuffer) message; byte[] bb = buffer.array(); for (int i = 0; i < bb.length; i++) { System.out.print((char) bb[i]); } System.out.println(""); System.out.println(""); IoBuffer buffer1 = IoBuffer.wrap("11".getBytes("UTF-8")); //返回信息给Clinet端 session.write(buffer1); Log.i("log_info", "messageReceived, " + formatter.format(curDate)); } // 一旦接受到广播就更新lastMsgReceived为当前时间 ListenerService.lastMsgReceived = System.currentTimeMillis(); }

请问我该怎么做才能让mina在锁屏的状态下也能接收到数据包呢？ 还是说mina在android上达不到这样的要求呢。。？
