Hello.
I am developing an application for online radio listening.
But I have two problems that I can not solve:
The first error is very problematic because when I give the play "play" button is activated stop "stop." So far so good, but if I press the Stop button before you start playing the audio, you stop off and activates the play but the application continues to play. This should not happen. I want the button to be pressed to activate when you begin to hear the audio, not when it starts to load.
The second is related to the ProgressBar. I do not know why it does not load the progress bar. If it shows but not charging.

I hope I have been explicit about the problems I have.
My Activity has this content:

import java.io.IOException;
import android.app.Activity;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnBufferingUpdateListene r;
import android.media.MediaPlayer.OnPreparedListener;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;

public class RadioActivity extends Activity implements OnClickListener {

private final static String RADIO_STATION_URL = "http://xxxxxxxxxxxxxxxxxxxx";

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.radio);

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.buttonStop);
buttonStopPlay.setEnabled(false);
buttonStopPlay.setOnClickListener(this);

}

@Override
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() {

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

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

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

private void initializeMediaPlayer() {
player = new MediaPlayer();
try {
player.setDataSource(RADIO_STATION_URL);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

player.setOnBufferingUpdateListener(new OnBufferingUpdateListener() {

@Override
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();**/
/**stopPlaying();**/
}

}


@Override
protected void onStop(){
super.onStop();
if (player.isPlaying()){
stopPlaying();
}
}




}


And my layout is this one:


<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#0069AD" >


<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="320dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:contentDescription="@string/imgreproductor"
android:src="@drawable/reproductor" />

<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/imageView1"
android:layout_centerHorizontal="true"
android:layout_marginTop="10dp"
android:text="@string/URL" />

<ProgressBar
android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="@dimen/anchoBarra"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView1"
android:layout_below="@+id/textView1"
android:layout_marginTop="2dp" />

<Button
android:id="@+id/buttonStop"
android:layout_width="@dimen/anchoPlay"
android:layout_height="wrap_content"
android:layout_alignRight="@+id/progressBar1"
android:layout_below="@+id/progressBar1"
android:layout_marginTop="13dp"
android:text="@string/Stop" />

<Button
android:id="@+id/buttonPlay"
android:layout_width="@dimen/anchoPlay"
android:layout_height="wrap_content"
android:layout_alignBaseline="@+id/buttonStop"
android:layout_alignBottom="@+id/buttonStop"
android:layout_alignLeft="@+id/progressBar1"
android:text="@string/Play" />

</RelativeLayout>


I hope your help and thank you very much beforehand.
