Android media player won't start

[Pavlex4]

I have created android application to stream online radio stations but when I click start button to play radio it won't start.In service I read ip address of file from url and add it to string.When user selects radio station I add port to string with ip address.

public class BackgroundService extends Service implements OnCompletionListener
{
MediaPlayer mediaPlayer;
private String STREAM_URL;
final String textSource = "http://audiophileradio.stream/Ip.txt";

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate()
    {

    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId)
    {
        new MyTask().execute();

        return START\_STICKY;
    }

    public void onDestroy() {
        if (mediaPlayer.isPlaying()) {
            mediaPlayer.stop();
        }
        mediaPlayer.release();
    }

    public void onCompletion(MediaPlayer \_mediaPlayer) {
        stopSelf();
    }


    @Override
    public boolean onUnbind(Intent intent)
    {
        return super.onUnbind(intent);
    }

    private class MyTask extends AsyncTask
    {
        String textResult;

        @Override
        protected String doInBackground(Void... params) {

            URL textUrl;

            try {
                textUrl = new URL(textSource);

                BufferedReader bufferReader
                        = new BufferedReader(new InputStreamReader(textUrl.openStream()));

                String StringBuffer;
                String stringText = "";
                while ((StringBuffer = bufferReader.readLine()) != null) {
                    stringText += StringBuffer;
                }
                bufferReader.close();

                textResult = stringText;
                return textResult;
            } catch (MalformedURLException e) {
                e.printStackTrace();
                textResult = e.toString();
            } catch (IOException e) {
                e.printStackTrace();
                textResult = e.toString();
            }

            return null;

        }

        @Override
        protected void onPostExecute(String resul

I have fixed the problem! Radio didn't work because I forgot to add http:// in ip address after reading it from url !!!
