QuestionAndroid media player won't start Pin

MemberPavlex413-May-17 2:08 
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<Void, Void, String>
        {
            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();

            }

                String radio = sharedPreferences.getString("station", "8000");

                if (radio != null)
                {
                    STREAM_URL += ":" + radio;
