Moto G的dosent收到了WIFI网络的UDP数据包 [英] Moto G dosent receive UDP packets over WIFI Network

问题描述

我的接收器没有收到Moto G的任何UDP数据包，但它适用于其他设备很好。

My receiver don't receive any UDP packet in Moto G but it works for other devices well.

在WiFi网络我已经从其他设备成功地发送UDP数据包。但在摩托E和Moto G的它不工作。

Over WiFi network I have send UDP packets successfully from other devices. But in Moto E and Moto G it is not working.

谁能帮助弄清楚为什么它不工作的摩托G / E？

Can anyone help figure out why it's not working for Moto G/E?

我的问题是，我是不会接受通过WiFi网络的UDP数据包。

My problem was that i was not Receiving any UDP Packets over WiFi Network.

推荐答案

试试这个code。这对我的工作。

Try this code. It's work for me.

 public void run() {
        Looper.prepare();
        try {
          WifiManager.MulticastLock lock;
          WifiManager wifi;

          wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
          if (Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
          if (lock == null)
          lock = wifi.createMulticastLock("WiFi_Lock");
          lock.setReferenceCounted(true);
          lock.acquire();
         }
      }
      catch(Exception e)
      {
        Log.d("Wifi Exception",""+e.getMessage().toString());
      }
    }
