Android Java.net.SocketException：socket failed：EACCES（Permission denied）

こんにちはみんなAndroidアプリを取得していますが、起動するとコンソールにエラーが表示されます。データグラムソケットを使用して接続を作成し、2つのクラスを使用しています。 MainActivity（アプリのメインアクティビティ）およびUdpClientServerで接続を作成します。

ここでコードMainActivity：

public class MainActivity extends Activity {

private UdpClientServer cu;
private EditText textIpScheda;
private EditText textUdpPort;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    textIpScheda = (EditText) findViewById(R.id.textIpScheda);
    textUdpPort = (EditText) findViewById(R.id.textUdpPort);


    try {
        cu = new UdpClientServer(this);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public EditText getTextIpScheda(){
    return textIpScheda;
}

public void setTextIpScheda(EditText textIpScheda){
    this.textIpScheda = textIpScheda;
}

public EditText getTextUdpPort() {
    return textUdpPort;
}

public void setTextUdpPort(EditText textUdpPort) {
    this.textUdpPort = textUdpPort;
}

ここで、コードUdpClientServer：

public class UdpClientServer {

public static String sReceive;
private static DatagramSocket dSocket;
int receiveBufferSize = 1024;
int portUdp = 0;
final String PINGACMD = "AT*PINGA001";
InetAddress ipScheda;

byte[] receiveData = new byte[receiveBufferSize];
private MainActivity gui = null;

public UdpClientServer(MainActivity gui) throws SocketException, IOException {
    this.gui = gui;

    portUdp = Integer.parseInt(String.valueOf(gui.getTextUdpPort().getText()));
    dSocket = new DatagramSocket(portUdp);
}

public void run(){
    while (true) {
        // svuotamento buffer
        Arrays.fill(receiveData, (byte) 0);
        DatagramPacket receivePacket = new DatagramPacket(receiveData, receiveData.length);

        try {
            dSocket.receive(receivePacket);
        } catch (IOException e) {
            e.printStackTrace();
        }
        ipScheda = receivePacket.getAddress();
        int port = receivePacket.getPort();
        gui.getTextUdpPort().setText("" + port);
        gui.getTextIpScheda().setText(ipScheda.getHostAddress());

        sReceive = new String(receivePacket.getData());
        this.sendCommand(PINGACMD);
    }

}

public void sendCommand(String outSentence){

    byte[] sendData = outSentence.getBytes();

    DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length, ipScheda, portUdp);

    try {
        dSocket.send(sendPacket);
        Thread.sleep(100);
    } catch (IOException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    finally {
    }
}

}

そして、ここlogcat：

私のAndroidManifest.xmlに文字列を追加しました

<uses-permission Android:name="Android.permission.INTERNET"/>

しかし、それは動作しません

手伝って頂けますか？ありがとう
