I'm doing an application and I need to receive an udp array from java to android and put it in a Spinner. Does anyone know how to do it?

Now, this is the code that I'm working with but I only receive a string.

Does anyone have an idea of ​​how I can receive the array working from this code?

UDPClientSocketActivity

  public class UDPClientSocketActivity extends AppCompatActivity implements View.OnClickListener {



  private TextView mTextViewReplyFromServer;

  private EditText mEditTextSendMessage;



  @Override

  protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_main);



  Button buttonSend = (Button) findViewById(R.id.btn_send);



  mEditTextSendMessage = (EditText) findViewById(R.id.edt_send_message);

  mTextViewReplyFromServer = (TextView) findViewById(R.id.tv_reply_from_server);



  buttonSend.setOnClickListener(this);

}



   @Override

   public void onClick(View v) {



   switch (v.getId()) {



        case R.id.btn_send:

             sendMessage(mEditTextSendMessage.getText().toString());

             break;

   }

}



      private void sendMessage(final String message) {



          final Handler handler = new Handler();

          Thread thread = new Thread(new Runnable() {



            String stringData;



            @Override

            public void run() {

                        DatagramSocket ds = null;

                        try {

                            ds = new DatagramSocket();

                            // IP Address below is the IP address of that Device where server socket is opened.

                           InetAddress serverAddr = InetAddress.getByName("xxx.xxx.xxx.xxx");

                           DatagramPacket dp;

                           dp = new DatagramPacket(message.getBytes(), message.length(), serverAddr, 9001);

                           ds.send(dp);



                           byte lMsg = new byte[1000];

                           dp = new DatagramPacket(lMsg, lMsg.length);

                           ds.receive(dp);

                           stringData = new String(lMsg, 0, dp.getLength());



            } catch (IOException e) {

                e.printStackTrace();

            } finally {

                if (ds != null) {

                    ds.close();

                }

            }



          handler.post(new Runnable() {



            @Override

            public void run() {

                String s = mTextViewReplyFromServer.getText().toString();

                if (stringData.trim().length() != 0)

                    mTextViewReplyFromServer.setText(s + "nFrom Server : " + stringData);



             }

         });

     }

 });

          thread.start();

   }

}
