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);
}
});
}

Android audio play and stop

this is the method am using..and will call whenever required...in my case i want to control that audio by one button whether it may toggle or button...
click to start and stop in one button
private void playSound() {
if (isFlashLightOn) {
mp = MediaPlayer.create(MainActivity.this, R.raw.light_switch_off);
} else {

}

An edited version of your code
private void playSound() {
if (isFlashLightOn) {
mp = MediaPlayer.create(MainActivity.this, R.raw.light_switch_off);
} else {
mp = MediaPlayer.create(MainActivity.this, R.raw.light_switch_on);
}
mp.prepareAsync(); //prepares the MediaPlayer
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
//MediaPlayer instance prepared
mp.start(); //play the content
playing=true;//update the flag
}
});
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release(); //playback finished
playing=false; //update the flag
}
});
}

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;
private MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.twelve_grm);

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.

Play wav using MediaPlayer

I am trying to read a wav file in raw file.
Here are the code i use:
MediaPlayer mPlayer = MediaPlayer.create(getActivity(), R.raw.error);
mPlayer.start();
I don't know why the wav is not played?

Try using setOnCompletionListener before the .start method of the mPlayer
button[i].setOnClickListener(new OnClickListener() {
public void onClick(View view) {
MediaPlayer mPlayer = MediaPlayer.create(getActivity(), R.raw.error);
mPlayer.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.release();
}
});
mPlayer.start();
}
});

I can't stop my media player in android?

Am using mediaplayer to play tick sound in timer.But it continues to play after timer is over,Even after i called stop for media player. I played sound as seen below in ontick() in timer. In onfinish() called mp.Stop(),But it not working.
mp = MediaPlayer.create(getBaseContext(), sound);
mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
});
mp.setLooping(false);
// mp.setVolume(0.1, 0.1);
mp.start();
}
coding for my timer .
final class MyCounter extends CountDownTimer {
public MyCounter(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
}
#Override
public void onFinish() {
timer.cancel();
MediaPlayer.OnCompletionListener onCompletion = new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
if (mp.isPlaying()) {
mp.release();
mp.stop();
mp.reset();
}
}
};
mp.setOnCompletionListener(onCompletion);
i++;
submitAnswer();
final GameEngine ge = GameEngine.getInstance();
timeer.setText("Timer Completed.");
if (ge.getCurrentUnAllocatedAmount() > 0 && i <= 8) {
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
Intent intent = new Intent(GameActivity.this,
ScoreActivity.class);
intent.putExtra("level", i);
ge.setCurrentLevel(i);
startActivity(intent);
}
}, 2200);
} else if (ge.getCurrentUnAllocatedAmount() <= 0 || i > 8) {
Intent intent = new Intent(GameActivity.this,
ScoreActivity.class);
intent.putExtra("level", i);
startActivity(intent);
}
}
public void onTick(long millisUntilFinished) {
remTime = (millisUntilFinished / 1000);
timeer.setText("Time:" + (millisUntilFinished / 1000) + "");
mp = MediaPlayer.create(getBaseContext(), R.raw.beep7);
if (remTime > 0) {
mp.start();
mp.release();
}
if (remTime < 10) {
final Handler handler = new Handler();
handler.post(new Runnable() {
public void run() {
if (timeer.getVisibility() == View.VISIBLE) {
timeer.setVisibility(View.INVISIBLE);
} else {
timeer.setVisibility(View.VISIBLE);
}
timeer.setTextColor(Color.RED);
}
});
}
}
}

Use this code:
if(mediaPlayer.isPlaying())
{
mediaPlayer.stop();
}

mp.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.stop();
});

try this:
mp.setOnCompletionListener(onCompletion);
private MediaPlayer.OnCompletionListener onCompletion = new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
if(mp.isPlaying())
{
mp.stop();
mp.reset();
}
}
};

I think you are not calling the release() method on the onCompletionListener() itself.
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.release();
});

mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
if (mp.isPlaying()) {
mp.stop();
}
mp.release();
mp = null;
}
});

Check condition when timer is stop.
if(mPlayer.isPlaying())
{
mPlayer.stop();
}
