Code to make a single MediaPlayer play more than one piece of sound in android studio

Being a novice coder, trying to code an app that plays a sound on buttonclick in a fragment; successfully did it but I want to add more small pieces of sounds to play one after another. How can I add those sounds(sound2, sound3, sound4, etc) after that 'R.raw.sound1'? Please guide..
buttonPlayAudioVar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mp != null) {
if(mp.isPlaying()){
mp.stop();
mp.release();
}
}
mp = MediaPlayer.create(getActivity().getApplicationContext(), R.raw.sound1);
mp.start();
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mediaPlayer) {
mp.release();
mp = null;
}
});
}
});

//you can add all the songs in a array
ArrayList<String> songsArray = new ArrayList<>();
int position = 0;
buttonPlayAudioVar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mediaPlayer(songsArray, position);
}
});
private void mediaPlayer(ArrayList<String> songsArray) {
if (mp != null) {
if (mp.isPlaying()) {
mp.stop();
mp.release();
}
}
if (position > songsArray.size() - 1) {
return;
}
try {
mp.setDataSource(songsArray.get(position));
position++;
mp.prepareAsync();
} catch (IOException e) {
e.printStackTrace();
}
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mediaPlayer) {
mp.release();
mp = null;
mediaPlayer(songsArray, position);
}
});
}

In My Music Player List View song item dose not work on second time click

I use thread to update the SeekBar. If I don't start the thread then this problem does not arise. What can I do now...? I only experience a problem with this part of my project.
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (mp != null) {
mp.stop();
mp.release();
toast("Second Time");
}
u = Uri.parse(collectedSong.get(position).toString());
mp = MediaPlayer.create(getApplicationContext(), u);
mp.start();
sb.setMax(mp.getDuration());
**updateSeekBar.start();**
positionNew = position;
}
});

Check out MediaPlayer lifecycle in Android documents:
https://developer.android.com/reference/android/media/MediaPlayer.html
this is how I use media player to play stream Song:
public void onSongClicked(Song song) {
//check if is playing
stopMediaPlayer();
// prepare media player to play sample
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
mMediaPlayer = null;
}
});
try {
mMediaPlayer.setDataSource(song.getPath());
mMediaPlayer.prepareAsync();
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void stopMediaPlayer() {
if (mMediaPlayer != null) {
mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
}
}
I hope it helps :)

something about android mp3 play

#Override
protected void onResume() {
playOrderSound();
super.onResume();
}
private void playOrderSound(Context context){
player= MediaPlayer.create(context, R.raw.order);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.start();
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
player.reset();
player.release();
}
});
player.setOnErrorListener(new MediaPlayer.OnErrorListener() {
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
player.start();
return false;
}
});
}
I put the sound source in the raw directory and use mediaPlayer to play it.When the server send message to me.I start a new activity and play the mp3 resource,but it does't work.
the new activity start with lauchmode singletask.

Try this Playing Well
#Override
protected void onResume() {
super.onResume();
playOrderSound(Mainactivity.this);
}
private void playOrderSound(Context context){
player = MediaPlayer.create(context, R.raw.acc);
player.start();
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
player.reset();
player.release();
}
});
player.setOnErrorListener(new MediaPlayer.OnErrorListener() {
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
player.start();
return false;
}
});
}
protected void onDestroy() {
super.onDestroy();
player.stop();
}

How to stop an object with the press of a button

I am fairly new to programming and having a tough time with a small problem. I have created an object which is initialized easily and starts working, how do i stop that object from functioning.
Following is my code:
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
animationFart();
playRandomSound();
}
private void playRandomSound() {
// TODO Auto-generated method stub
int randomInt = (new Random().nextInt(soundList.size()));
int sound = soundList.get(randomInt);
MediaPlayer mp = MediaPlayer.create(btn.getContext(), sound);
mp.start();
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.release();
}
});
}
});
How can i stop this with the press of a button.

Define MediaPlayer mp; globally and use mp.stop();:
if (mp!=null && mp.isPlaying()) {
mp.stop();
}

use this class
public class AudioPlayer {
private MediaPlayer mediaPlayer;
public void play(Context context, int resId) {
stop();
mediaPlayer = MediaPlayer.create(context, resId);
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
stop();
}
});
mediaPlayer.start();
}
public void stop() {
if (mediaPlayer != null) {
mediaPlayer.release();
mediaPlayer = null;
}
}
public boolean isPlaying() {
return mediaPlayer != null;
}
}

How to keep my audio from overlapping

I have a simple listview with the name of some songs. When you click on one of the childs, the song plays. However, I noticed that when you accidentally tap it again while its playing, it start to play again causing the sounds to overlap. How can I set it up so that when you click on one song and then click on another song, the first song stop and the second song begins. How can I modify my code to accomplish this. Any help would be appreciated.
public class TwelveGrammar extends ActionBarActivity {
private ListView lv;

I think you should have one boolean like boolean isAnotherSongPlaying and if it's true the previous song should be stopped and the new one should start. And I believe that the best way to handle mediaplayer is a Service. I'm not yet too familiarized with that but I have implemented a Service for background music and its control depending on user's actions and it works quite well.
MyService.class
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.os.IBinder;
public class MyService extends Service implements OnCompletionListener {
MediaPlayer mediaPlayer;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
mediaPlayer = MediaPlayer.create(this, R.raw.music);// raw/s.mp3
mediaPlayer.setLooping(true);
mediaPlayer.setOnCompletionListener(this);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (!mediaPlayer.isPlaying()) {
mediaPlayer.start();
}
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
}
mediaPlayer.release();
}
public void onCompletion(MediaPlayer _mediaPlayer) {
stopSelf();
}
}
in my main activity I have one button which starts and stops the service depending whether the music is playing or not
Intent play;
play = new Intent(getApplicationContext(), MyService.class);
...
sound.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
if(isPlaying){
stopService(play);
isPlaying = false;
sound.setText("Yes");
} else {
startService(play);
isPlaying = true;
sound.setText("No");
}
}
});
Search it also on google you'll find some good tutorials. Hope I helped you.
