According to the MediaPlayer life cycle, which you can view in the Android API guide, I think that you have to call reset() instead of stop(), and after that prepare again the media player (use only one) to play the sound from the beginning. Take also into account that the sound may have finished. So I would also recommend to implement setOnCompletionListener() to make sure that if you try to play again the sound it doesn't fail.

The problem is that when you stop mediaplayer and click on play again your call will go to mediaplayer.play() as mediaplayer is not null.
You will have to null the mediaPlayer on stop method. Now, once you stop mediaplayer and again click on play it will call playMonthLesson();
#OnClick(R.id.lesson_stop)
public void setLesson_stop(View view) {
if (mediaPlayer != null) {
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer = null;
lesson_play.setImageResource(R.drawable.ic_play);
lesson_progress_bar.setProgress(0);
}
}
change this code too,
#SuppressLint("DefaultLocale")
public void playMonthLesson() {
try {
mediaPlayer = new MediaPlayer();
mediaPlayer.reset();
mediaPlayer.setDataSource(CoreApplication.MEDIAFOLDER + "/" + lesson.getFilename());
mediaPlayer.setOnPreparedListener(new OnPreparedListener(){
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
lesson_play.setImageResource(R.drawable.ic_pause);
int totalDuration = mediaPlayer.getDuration();
}
});
mediaPlayer.prepareAsync();
// set Progress bar values
lesson_progress_bar.setProgress(curretLessonProgress);
lesson_progress_bar.setMax(100);
// Updating progress bar
updateProgressBar();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

Android MediaPlayer: Multiple sounds playing at the same time. My code is

I have searched and researched stackoverflow and google but can't find any answer to MY question. I've found other question and answers but that were related to sounds saved in the app but I'm creating an app which gets data from Parse server, so it gets mp3 files and display these in listview and than when an item is clicked it plays that track. But here comes the problem: When you play a sound and click on another one, the first just doesn't stop and the second starts to play.
I have tried with the following code but it's just not working.
Here's my code:
play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final MediaPlayer mediaPlayer = new MediaPlayer();
final MediaPlayer scndmediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
scndmediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
if (mediaPlayer.isPlaying()) {
Toast.makeText(getContext(), "First is playing", Toast.LENGTH_SHORT).show();
try {
mediaPlayer.stop();
scndmediaPlayer.setDataSource(audioFileURL);
scndmediaPlayer.prepare();
scndmediaPlayer.start();
//soundtoolbar.setTitle(name);
} catch (IllegalArgumentException e1) {
e1.printStackTrace();
} catch (SecurityException e1) {
e1.printStackTrace();
} catch (IllegalStateException e1) {
e1.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} else {
try {
if (scndmediaPlayer.isPlaying()){
scndmediaPlayer.stop();
}
Toast.makeText(getContext(), "First is starting", Toast.LENGTH_SHORT).show();
mediaPlayer.setDataSource(audioFileURL);
mediaPlayer.prepare();
mediaPlayer.start();
soundtoolbar.setTitle(name);
} catch (IllegalArgumentException e1) {
e1.printStackTrace();
} catch (SecurityException e1) {
e1.printStackTrace();
} catch (IllegalStateException e1) {
e1.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
playPause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mediaPlayer.isPlaying() || scndmediaPlayer.isPlaying()) {
mediaPlayer.pause();
scndmediaPlayer.pause();
playPause.setBackground(getContext().getDrawable(R.drawable.ic_play_arrow_white_24dp));
} else {
mediaPlayer.start();
scndmediaPlayer.start();
playPause.setBackground(getContext().getDrawable(R.drawable.ic_pause_white_24dp));
}
}
});
}
});
I've created 2 mediaplayers with the code above and when user clicks the play button it first checks if any of the player is running.
I'm trying to achieve the following: When user clicks the play button it checks if the (1st) mediaPlayer is running or not. If it's running, it has just to stop it and launch (2nd) scndmediaPlayer or viceversa... if second is playing it stops that and launch first one. so it will create a loop: 1st is playing? User clicks another button stop first. Launch second. User clicks another button. First is playing? No. Second is playing? Yes. Stop the second and launch the first.
But can't find where is the problem in my code.
Please help me with this. I'm trying to resolve it from 2 days but I'm unable...
Thanks :)
EDIT: I tried using one MediaPlayer and do the following: Check if mediaplayer is playing! No it isn't playing. Start it. User clicks the button again and it stops the mediaplayer and start it with new audioFileUrl. BUT. MediaPlayer is forgetting that it's playing. Seems like it just starts the track and than forget and to check if it's true i set a Toast: when mediaplayer isn't playing the toast shows and it's showing every time I click a track in the list which means it forget that it has a track which is playing...
EDIT 2: I managed to do the following: It plays the track. User clicks another track. It stops the mediaplayer but doesn't play the new track. User click once again. It plays the new track. User clicks the new track and the app crashes...

Somebody please help...

i suggest you to checkout SoundPool . İt ll helps you. And one more , may be you ll put media urls to array or something like this.And use one mediaPlayer By the way, you ll avoid from two mediaPlayer and avoid from memory leak.

Adding delay while Mediaplayer loops

Playing .wav file using MediaPlayer class. As I need to loop the Audio I've set .setLooping(true); . So obviously, the doubt is how do I add a delay each time the audio plays, say I want a delay of 5000 .
The answers to similar questions here doesn't work in my case. Any help would be appreciated. Here is my code:
Button Sample = (Button)findViewById(R.id.samplex);
Sample.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String filePath = Environment.getExternalStorageDirectory()+"/myAppCache/wakeUp.wav";
try {
mp.setDataSource(filePath);
mp.prepare();
mp.setLooping(true);
}
catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mp.start();
}
});

You need to register 2 listeners (on completion and on error) and then you would need to delay next play in on completion callback. Reason for the error listener is to return true to avoid calling on completion event whenever there is an error - explanation here
private final Runnable loopingRunnable = new Runnable() {
#Override
public void run() {
if (mp != null) {
if (mp.isPlaying() {
mp.stop();
}
mp.start();
}
}
}
mp.setDataSource(filePath);
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
button.postDelayed(loopingRunnable, 5000);
}
});
mp.setOnErrorListener(new MediaPlayer.OnErrorListener() {
...
return true;
});
mp.prepare();
// no need to loop it since on completion event takes care of this
// mp.setLooping(true);
Whenever your destruction method is (Activity.onDestroyed(), Fragment.onDestroy(), View.onDetachedFromWindow()), ensure you are removing the runnable callbacks, e.g.
#Override
protected void onDestroy() {
super.onDestroy();
...
button.removeCallbacks(loopingRunnable);
if (mp != null) {
if (mp.isPlaying()) {
mp.stop();
}
mp.release();
mp = null;
}
}

Android Media Player Replay Option

How can i replay a .mp3 in my app? I can't replay the mp3 using the start method
Here is the code segment :
mMediaPlayer = MediaPlayer.create(MainActivity.this, R.raw.splashsound);
mMediaPlayer.setLooping(true);
Button myButtonOne = (Button) findViewById(R.id.songon);
myButtonOne.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mMediaPlayer.start();
}
});
Button myButtonTwo = (Button) findViewById(R.id.songoff);
myButtonTwo.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(mMediaPlayer.isPlaying()){
//mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
}
}
});
Can anyone please tell me what i am doing wrong here?

If you want to replay the mp3 why do release and set to null your media player?
I guess that is your problem!
Just stop and start it again without releasing your media player instance.

To replay mp3 track try this:
private void playSong(int songIndex) {
// Play song
try {
mp.reset();
mp.setDataSource(songsList.get(songIndex).get("songPath"));
mp.prepare();
mp.start();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
Or without calling reset():
mediaPlayer.setLooping(true);

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
