super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button reg = (Button) findViewById(R.id.regButton);
reg.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
EditText hostEle = (EditText) findViewById(R.id.apnHost);
Editable host = hostEle.getText();

try {
DatagramSocket socket = new DatagramSocket(4567);
InetAddress serverAddress = InetAddress
.getByName("10.0.2.2");
String str = "hello";
byte data[] = str.getBytes();
DatagramPacket packet = new DatagramPacket(data,
data.length, serverAddress, 9999);
socket.send(packet);
} catch (SocketException e) {
Log.e("liangyf.mobile.terminal", "发生异常：", e);
} catch (IOException e) {
Log.e("liangyf.mobile.terminal", "发生异常：", e);
}
}
});
同时我在开发机（运行模拟器的机器）上开启了9999端口侦听，但是当运行app进行连接时发生错误：

我已经对app添加了android.permission.INTERNET权限：
<uses-permission android:name="android.permission.INTERNET"/>
有知道的告诉我怎么回事？
