Quiero almacenar un audio de Mi teléfono Android a través de wifi y todos los demás teléfonos Android que tengan mi aplicación deberían recibir el audio si están en la misma red. ¿Puedo obtener una manera de enviar buffers desde Android. Mi código lo copié de algún enlace. No funciona.

public class MainActivity extends Activity {

private Button startButton,stopButton,listenButton;

public byte[] buffer;
public static DatagramSocket socket;
    AudioRecord recorder;

private int sampleRate = 8000;   
private int channelConfig = AudioFormat.CHANNEL_CONFIGURATION_MONO;    
private int audioFormat = AudioFormat.ENCODING_PCM_16BIT;       
int minBufSize = AudioRecord.getMinBufferSize(sampleRate, channelConfig, audioFormat);
    private boolean status = true;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     startButton = (Button) findViewById (R.id.start_button);
     stopButton = (Button) findViewById (R.id.stop_button);
     listenButton = (Button)findViewById(R.id.listen_button);

     startButton.setOnClickListener(startListener);
     stopButton.setOnClickListener(stopListener);
     listenButton.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(MainActivity.this,VoiceReceiveActivity.class);
            startActivity(intent);
        }
    });

     minBufSize += 2048;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

private final OnClickListener stopListener = new OnClickListener() {

    @Override
    public void onClick(View arg0) {
                status = false;
                recorder.release();
                Log.d("VS","Recorder released");
    }


};

private final OnClickListener startListener = new OnClickListener() {

    @Override
    public void onClick(View arg0) {
                status = true;
                startStreaming();           
    }
};



public void startStreaming()
{
    Thread streamThread = new Thread(new Runnable(){
        @Override
        public void run()
        {
            try{

                DatagramSocket socket = new DatagramSocket();
                Log.d("VS", "Socket Created");

                byte[] buffer = new byte[minBufSize];

                Log.d("VS","Buffer created of size " + minBufSize);


                Log.d("VS", "Address retrieved");
                recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,sampleRate,channelConfig,audioFormat,minBufSize);
                Log.d("VS", "Recorder initialized");


                recorder.startRecording();


                InetAddress IPAddress = InetAddress.getByName("192.168.1.5");
                byte[] sendData = new byte[1024];

                byte[] receiveData = new byte[1024];


                while (status == true)
                {
                    Log.i("TAG",""+sendData.length);
                    DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length, IPAddress, 50005);
                    socket.send(sendPacket);
                }

            } catch(UnknownHostException e) {
                Log.e("VS", "UnknownHostException");
            } catch (IOException e) {
                Log.e("VS", "IOException");
                e.printStackTrace();
            } 


        }

    });
    streamThread.start();
}

}

Necesitas ayuda. Gracias de antemano
