Answer 1

Try this.

public class RadioStream extends Activity {

    private final static String stream = "http://bbcmedia.ic.llnwd.net/stream/bbcmedia_radio2_mf_p";
    Button play;
    MediaPlayer mediaPlayer;
    boolean started = false;
    boolean prepared = false;

    /**
     * Called when the activity is first created.
     */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_radio_stream);

        play = (Button) findViewById(R.id.play);
        play.setEnabled(false);
        play.setText("Loading..");
        mediaPlayer = new MediaPlayer();
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

        play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                if (started) {
                    mediaPlayer.pause();
                    started = false;
                    play.setText("Play");
                } else {
                    mediaPlayer.start();
                    started = true;
                    play.setText("Pause");
                }

            }
        });

        new PlayTask().execute(stream);
    }

    @Override
    protected void onPause() {
        super.onPause();
       /* if(started)
            mediaPlayer.pause();*/

    }

    @Override
    protected void onResume() {
        super.onResume();
        /*if(started)
            mediaPlayer.start();*/
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        // mediaPlayer.release();
    }

    private class PlayTask extends AsyncTask<String, Void, Boolean> {

        @Override
        protected Boolean doInBackground(String... strings) {

            try {
                mediaPlayer.setDataSource(strings[0]);
                mediaPlayer.prepare();
                prepared = true;
            } catch (IOException e) {
                e.printStackTrace();
            }
            return prepared;
        }

        @Override
        protected void onPostExecute(Boolean aBoolean) {
            super.onPostExecute(aBoolean);
            play.setEnabled(true);
            play.setText("Play");

        }
    }
}

Please do try the code below and call the given method at the on create of your activity or at the onclick listener of your button. Remember to handle the stop and start button the imgV is an imageView for my button.

 private MediaPlayer player;
private void startMediaPlayer() {
    String url = "http:yoururl.com"; // your URL here
    mediaPlayer = new MediaPlayer();
    mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    try {
        mediaPlayer.setDataSource(url);
    } catch (IllegalArgumentException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (SecurityException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IllegalStateException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    if(isPlaying){
        try {
            mediaPlayer.prepareAsync();
            progress.setVisibility(View.VISIBLE);
        } catch (IllegalStateException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        mediaPlayer.setOnPreparedListener(new OnPreparedListener() {

            public void onPrepared(MediaPlayer mp) {
                mediaPlayer.start();
            }
        });
    }
    mediaPlayer.setOnBufferingUpdateListener(new OnBufferingUpdateListener() {

        public void onBufferingUpdate(MediaPlayer mp, int percent) {
        }
    });
}

boolean isPlaying = true;
 private void startPlaying() {
    isPlaying = true;
    mediaPlayer.prepareAsync();
    mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
        public void onPrepared(MediaPlayer mp) {
            mediaPlayer.start();
        }
    });
    imgV.setImageResource(R.drawable.stop);
}

private void stopPlaying() {
    if (mediaPlayer.isPlaying()) {
        isPlaying = false;
        mediaPlayer.stop();
        mediaPlayer.release();
        initializeMediaPlayer();
    }
    imgV.setImageResource(R.drawable.play);
}
