Play audio from url one after other

I want to play/stream audio from url one after other automatically.
here what I have tried:
final String audioUrl[] = {"https://www.googleapis.com/storage/v1/b/ezconnectpoc/o/NV.wav?alt=media", "https://www.googleapis.com/storage/v1/b/ezconnectpoc/o/cqo.wav?alt=media"};
backtobackButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try {
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(audioUrl[currentTrack]);
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
try {
Log.d("Current track",currentTrack+"");
Log.d("audioUrl.length",audioUrl.length+"");
if (currentTrack < audioUrl.length) {
currentTrack++;
mediaPlayer.setDataSource(audioUrl[currentTrack]);
mediaPlayer.setOnCompletionListener(this);
mediaPlayer.start();
}
mediaPlayer.stop();
} catch (Exception e) {
e.printStackTrace();
}
}
});
} catch (Exception e) {
e.printStackTrace();
// make something
}
}
});
My first audio url gets played when I click on backtoback named button but failed to play second audio from url.

changed this part of code
mediaPlayer.reset();
mediaPlayer.setDataSource(audioUrl[currentTrack]);
mediaPlayer.prepareAsync();
mediaPlayer.setOnCompletionListener(this);
mediaPlayer.start();
currentTrack++;
and worked.

android Media player not reading some mp3 url

i've created a playlist based on Media Player class. The thing is that it succeed in reading some mp3 url and it doesn't for another ones.
For example here is a directory of mp3 i've uploaded but no one is working:
http://rajaapp12.0fees.us/gbv3/
in the other hands an mp3 which work:
http://mp3.mp3zik.com/music/Music-Rap/Casa%20Verde%202009/track%20(14).mp3
I don't think there is a problem with the code since it works already witch some url, but here is the most iportant part of it :
public void beginLrcPlay(){
killMediaPlayer();
mPlayer = new MediaPlayer();
try {
mPlayer.setDataSource(songEnCours.getSource_128());
mPlayer.setLooping(true);
mPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
mp.start();
if (mTimer == null) {
mTimer = new Timer();
mTask = new LrcTask();
mTimer.scheduleAtFixedRate(mTask, 0, mPalyTimerDuration);
}
}
});
mPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
//fin musique ajouter action !
stopLrcPlay();
chantSuivant();
btnPlay.setImageResource(R.drawable.bg_selector_btn_play);
}
});
mPlayer.setOnBufferingUpdateListener(onBufferingUpdateListener);
mPlayer.prepare();
mPlayer.start();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

How to stop or cancel Mediaplayer.setOnPreparedListener form executing Android

MediaPlayer player;
protected void playaudio() {
player = new MediaPlayer();
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
System.out.println("setOnPreparedListener executed");
mediaPlayer.start();
}
});
try {
player.setDataSource(mContext,
Uri.parse("http://radio-electron.ru:8000/96"));
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (IOException e) {
e.printStackTrace();
return;
}
player.prepareAsync();
}
public void stopaudio() {
if (player != null) {
player.stop();
player.reset();
player.release();
player = null;
}
}
Even if i call stopaudio() method, the code inside setOnPreparedListener is executed. How can i stop or cancel the setOnPreparedListener from execution when i stop the player. thanks in advance...

you can reset the listener instance, passing null as parameter. E.g.
player.setOnPreparedListener(null);
on stopaudio()

if (mediaPlayer != null) {
mediaPlayer.release();
mediaPlayer = null;
}
You can use above code before the declaration of player = new MediaPlayer();
Like:-
MediaPlayer player;
protected void playaudio() {
if (mediaPlayer != null) {
mediaPlayer.release();
mediaPlayer = null;
}
player = new MediaPlayer();
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
System.out.println("setOnPreparedListener executed");
mediaPlayer.start();
}
});
try {
player.setDataSource(mContext,
Uri.parse("http://radio-electron.ru:8000/96"));
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (IOException e) {
e.printStackTrace();
return;
}
player.prepareAsync();
}
public void stopaudio() {
if (player != null) {
player.stop();
player.reset();
player.release();
player = null;
}
}
I hope it works for you.

android mediaplayer start called in state1

I am trying to play an audio file when the app started, but I am getting an error says that start called in state 1 Error (-38,0), here is my code:
public void audioPlayer(){
//set up MediaPlayer
MediaPlayer mp = new MediaPlayer();
try {
mp.create(this, R.raw.music);
onPrepared(mp);
} catch (Exception e) {
e.printStackTrace();
}
}
public void onPrepared(MediaPlayer mp) {
mp.start();
}

public void audioPlayer(){
MediaPlayer mp = new MediaPlayer();
mp.setOnPreparedListener(mListener);
try {
mp.setDataSource(this, R.raw.music);
mp.prepare();
} catch (Exception e) {
e.printStackTrace();
}
}
private OnPreparedListener mListener=new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
};

Trigger an event when mediaPlayer stops

I am making an app that uses sound effects. I would like to know how i can detect when a sound has finished playing and trigger an event .
i tried this :
player = new MediaPlayer();
if (player != null) {
player.reset();
player.release();
}
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
sonar.setBackgroundResource(R.drawable.sonar_off);
stopPlay();
}
});
if(state==1){
player = MediaPlayer.create(this, R.raw.sonar_slow);
}else if(state==2){
player = MediaPlayer.create(this, R.raw.sonar_medium);
}else if(state==3){
player = MediaPlayer.create(this, R.raw.sonar_fast);
}
try{
player.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
player.start();

You can set an OnCompleteListener() to the player object. The code for it is:
mPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp)
{
"your code comes here"
}
});
Here the mPlayer is the object of the MediaPlayer which is currently running.

There are multiple ways to play sounds, assuming you use the MediaPlayer class you could register a MediaPlayer.OnCompletionListener
