对于一些android2.3系统休眠服务的处理（原创）

对于一些 对于一些android2.3系统休眠后，你的服务可能也不行了，需要进行单独处理，具体代码如下：

// BroadcastReceiver for handling ACTION_SCREEN_OFF.    

private BroadcastReceiver mReceiver = new BroadcastReceiver() {        

@Override        

public void onReceive(Context context, Intent intent) 

{            

// Check action just to be on the safe side.            

if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {                

// Unregisters the listener and registers it again.                

releaseWakeLock();

acquireWakeLock();

}        

}    

};

private void sendBroad(String filter,String sKey,int nValue){

Intent i = new Intent(filter);

i.putExtra(sKey, nValue);

sendBroadcast(i);

}

    private void acquireWakeLock() 

    {

if (wl != null) 

{

wl.release();

}

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);

wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "gmlc.com.wuliu");

if (null != wl) {

wl.acquire();

wl.setReferenceCounted(false);

}  

    }

    private void releaseWakeLock()

    {

if (null != wl) {

wl.release();

wl = null;

}

    }
