Online radio streaming app for Android

So I found this sample and it works for me, here it is if you have the same issue:

in myMain.java

import android.app.Activity;
import android.os.Bundle;

import java.io.IOException;

import android.media.MediaPlayer;
import android.media.MediaPlayer.OnBufferingUpdateListener;
import android.media.MediaPlayer.OnPreparedListener;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;

public class myMain extends Activity implements OnClickListener {

    private ProgressBar playSeekBar;

    private Button buttonPlay;

    private Button buttonStopPlay;

    private MediaPlayer player;

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

        initializeUIElements();

        initializeMediaPlayer();
    }

    private void initializeUIElements() {

        playSeekBar = (ProgressBar) findViewById(R.id.progressBar1);
        playSeekBar.setMax(100);
        playSeekBar.setVisibility(View.INVISIBLE);

        buttonPlay = (Button) findViewById(R.id.buttonPlay);
        buttonPlay.setOnClickListener(this);

        buttonStopPlay = (Button) findViewById(R.id.buttonStopPlay);
        buttonStopPlay.setEnabled(false);
        buttonStopPlay.setOnClickListener(this);

    }

    public void onClick(View v) {
        if (v == buttonPlay) {
            startPlaying();
        } else if (v == buttonStopPlay) {
            stopPlaying();
        }
    }

    private void startPlaying() {
        buttonStopPlay.setEnabled(true);
        buttonPlay.setEnabled(false);

        playSeekBar.setVisibility(View.VISIBLE);

        player.prepareAsync();

        player.setOnPreparedListener(new OnPreparedListener() {

            public void onPrepared(MediaPlayer mp) {
                player.start();
            }
        });

    }

    private void stopPlaying() {
        if (player.isPlaying()) {
            player.stop();
            player.release();
            initializeMediaPlayer();
        }

        buttonPlay.setEnabled(true);
        buttonStopPlay.setEnabled(false);
        playSeekBar.setVisibility(View.INVISIBLE);
    }

    private void initializeMediaPlayer() {
        player = new MediaPlayer();
        try {
            player.setDataSource("http://usa8-vn.mixstream.net:8138");
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        player.setOnBufferingUpdateListener(new OnBufferingUpdateListener() {

            public void onBufferingUpdate(MediaPlayer mp, int percent) {
                playSeekBar.setSecondaryProgress(percent);
                Log.i("Buffering", "" + percent);
            }
        });
    }

    @Override
    protected void onPause() {
        super.onPause();
        if (player.isPlaying()) {
            player.stop();
        }
    }
}

in the XML (main.xml) code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:text="Source: (Radio La Chevere)"
        android:layout_marginTop="10dip" android:gravity="center" />
<ProgressBar android:id="@+id/progressBar1"
        android:indeterminateOnly="false" android:progressDrawable="@android:drawable/progress_horizontal"
        android:indeterminateDrawable="@android:drawable/progress_indeterminate_horizontal"
        android:minHeight="20dip" android:maxHeight="20dip"
        android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:layout_marginLeft="20dip" android:layout_marginRight="20dip"
        android:layout_marginTop="10dip"></ProgressBar>
<LinearLayout android:id="@+id/linearLayout1"
        android:layout_height="wrap_content" android:layout_width="match_parent"
        android:layout_marginTop="20dip" android:gravity="center">
        <Button android:text="Play" android:id="@+id/buttonPlay"
                android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
        <Button android:text="Stop" android:id="@+id/buttonStopPlay"
                android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>
</LinearLayout>

and the android manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="package.your.RadioStream"
  android:versionCode="1"

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".myMain"
              android:label="@string/app_name">

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

</application>
