Media Player working only in debug mode

I am using MediaPlayer to playback audio file of .WAV format. When I debug the app I'm able to play file but when I run the app file is not playing.
There is a similar issue regarding this but no solution is provided.
Below is the code which i am using
MediaPlayer mMediaPlayer = new MediaPlayer();
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setDataSource(mContext, fileUri);// uri of the audio file
mMediaPlayer.prepare();
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.start();// to start the playback of the audio file
This code is working only in debug mode but not in normal mode.
Thanks

This is what I am saying:
btn_next.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mp.reset();
mp.setDataSource(url.toString());
mp.setOnErrorListener(this);
mp.setOnPreparedListener(this);
mp.setOnCompletionListener(this);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
Log.e(TAG, "SecurityException");
} catch (IllegalStateException e) {
Log.e(TAG, "IllegalStateException");
} catch (IOException e) {
Log.e(TAG, "IOException");
}
mp.prepareAsync();
}
});
Now, override method onPrepared().
#Override
public void onPrepared(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.start();
}
Comment below if you face any issue in this.

3 audios at the same time with Android MediaPlayer

I am trying to play 3 audios width Android but not at the same time, my code is the next one:
for (Word w : wordsList){
String path = Parameters.PATH_AUDIO + "/" + w.getAudioPath();
Uri audioPath = Uri.parse(path);
MediaPlayer audio1 = MediaPlayer.create(context, audioPath);
audio1.start();
}
But all audios start to play at least at the same time. I need something like audio1.wait() or audio1.sleep or someone like this.

You might want to consider using setOnCompletionListener:
audio1.setOnCompletionListener(new MediaPlayer.OnCompletionListener(){
public void onCompletion(MediaPlayer player) {
//do something when audio is finished
}});
Here's an example (didn't have the chance to try it though):
Decalre these in the class level:
int index = 0;
MediaPlayer audio1;
and then:
try {
audio1 = MediaPlayer.create(this, Uri.parse(yourList.get(index)));
audio1.start();
index++;
audio1.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer player) {
if (index < yourList.size()) {
audio1.reset();
audio1 = MediaPlayer.create(MainActivity.this,
Uri.parse(yourList.get(index)));
audio1.start();
index++;
}
else
{
//release it
}
}
});
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

how to start a media player once stopped

I have added two buttons to my app, one to play and one to start. As soon as i start the app the songs starts playing automatically. when i press on stops it stops but when i press on play it doesnt starts again
To stop I have used mediaplayer.stop() which is working fine
To start I have used
mediaplayer.start()
which is not working
According to flow diagram its given we need to use
prepare()
and then
OnPreparedListener.onPrepared()
and then
start()
I don't know how to use these functions. Please help me

Don't call stop() for stopping the mediaplayer use reset() instead. I dont have good reason for that. But, it'll work for sure.
// for stopping it call below statement
if(mediaPlayer.isPlaying())
mediaPlayer.reset();
//for playing it again
mediaPlayer.prepare();
mediaPlayer.start();

For starting media player again use following code.
if (mediaplayer != null) {
mediaplayer.start();
}
and one more thing, instead of using
mediaplayer.stop()
use
mediaplayer.pause();
so it will pause the current song instead of stop.
Just check the condition whether it is null or not.

Try following code on Play Button
mp.reset();
mp.setDataSource(song path);
mp.prepare();
mp.start();
mp.setDataSource(song path); not necessary if you playing same sound again

MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.singleitemview);
btnsound=(Button)findViewById(R.id.play_sound);
btnstopsound=(Button)findViewById(R.id.stop_sound);
mp=new MediaPlayer();
btnsound.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try {
mp.setDataSource(Sound);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mp.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.start();
mp.setLooping(true);
}
});
btnstopsound.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.setLooping(false);
mp.stop();
}
});
}

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

How can I repeat audio without stopping it?

I want to repeat playing audio. so if first clicking button audio play, and second clicking same button repeat same audio without stopping. How can I do this? Here's what I've tried:
if (mp != null){
mp.stop();
try {
mp.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.seekTo(0);
mp = null;
}
else {
mp = MediaPlayer.create(Takbiratul_Ihram.this, R.raw.takbir_cowok);
mp.start();
mp.setOnCompletionListener(new OnCompletionListener(){
public void onCompletion (MediaPlayer arg0){
mp = null;
}
});

mediaPlayer.setLooping(true);
