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.

MediaPlayer and error when playing music from online

mediaPlayer=new MediaPlayer();
mediaPlayer.reset();
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();
}
});
try {
mediaPlayer.setDataSource("192.168.191.1/test.mp3");
} catch (IOException e) {
e.printStackTrace();
}
mediaPlayer.prepareAsync();
above is my code. It works well from such url: http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3
But it don't work when I try to access mp3 file in my server, 192.168.191.1/test.mp3, and I use wamp for my server.

I had the same requirement and it is working on my end :
MediaPlayer player = new MediaPlayer();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setDataSource("mp3 link"
);
player.prepare();
player.start();
} catch (Exception e) {
// TODO: handle exception
}

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

Working with MP3 sound in Processing for Android ( need to stop )

I am developing an app for Android devices using Processing 2.0, now I have playMP3(); function but need to stop the sound using stopMP3();. I tried everything but what is the best way to load an mp3 and play/stop using processing?, snd.stop(); within the stopMP3 function does not work...
import android.media.*;
import android.content.res.*;
...
MediaPlayer snd;
...
void setup()
{
MediaPlayer snd = new MediaPlayer();
}
...
void playMP3()
{
try {
AssetManager assets = this.getAssets();
AssetFileDescriptor fd = assets.openFd("loop1.mp3");
snd.setDataSource(fd.getFileDescriptor(), fd.getStartOffset(), fd.getLength());
snd.prepare();
snd.start();
snd.setLooping(true);
}
catch (IllegalArgumentException e) {
e.printStackTrace();
}
catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
void stopMP3(){
????
}

this is a simple sample for media player
private MediaPlayer m_Player;
//Start Play Function
private void startPlaying() {
m_Player = new MediaPlayer();
m_Player.setOnCompletionListener(onComplete);
try {
if(m_Player.isPlaying())
stopPlaying();
m_Player.setDataSource(m_FileName);
m_Player.prepare();
m_Player.start();
} catch (IOException e) {
}
}
//Stop Play Function
private void stopPlaying() {
m_Player.stop();
m_Player.reset();
m_Player = null;
}
//and this is onComplete Listener
MediaPlayer.OnCompletionListener onComplete = new OnCompletionListener()
{
#Override
public void onCompletion(MediaPlayer mp)
{
stopPlaying();
}
};
i hope it's helping you
