Play .mp3 using MediaPlayer just one time and not loop

So I have a .mp3 in assets folder (I plan to have many more later) and I have a simple click associated to play it:
public static MediaPlayer m = new MediaPlayer();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button= (Button) findViewById(R.id.btnDrum);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
PlayMusic(v);
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
private void PlayMusic(View v) throws IOException {
try {
if (m.isPlaying()) {
m.stop();
m.release();
m = new MediaPlayer();
}
AssetFileDescriptor descriptor = getAssets().openFd(Kit.KickDrum);
m.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());
descriptor.close();
m.prepare();
m.setVolume(1f, 1f);
m.setLooping(true);
m.start();
} catch (Exception e) {
e.printStackTrace();
}
}
However, every-time I try to click the button, I the music plays in loop! I just need it to play once and stop! How can this be done?
Thanks!

you are setting it for looping using m.setLooping(true); change it to false

try this code
try {
Uri mp3 = Uri.parse("url");
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(context, mp3);
mediaPlayer.prepare(); // might take long! (for buffering, etc)
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(onCompletionListener);
} 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();
}
// onCompletionListerner
private OnCompletionListener onCompletionListener = new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
mediaPlayer.release();
mediaPlayer = null;
}
};

Media Player called in state 0, error (-38,0) error

i'm trying to use this code which i called from a button but it doesn't work and when i see the LogCat window i found Media Player called in state 0, error (-38,0)
public void audioPlayer(String path, String fileName){
//set up MediaPlayer
MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(HeyActivity.this, Uri.parse(path+"/"+fileName));
} catch (IllegalArgumentException 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
System.out.print("hey");
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.start();
}

Try setting OnPreparedListener and call the start method within it. Like this:
MediaPlayer mp = new MediaPlayer();
mp.setOnPreparedListener( new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
mp.start();
}
};
);

I finally solved the problem by running on an emulator that supported audio!!
Can't believe it was that simple!

Android play sound - forceclose error

I am using below code to play wav sound on touch of imageview
MediaPlayer mp = MediaPlayer.create(this, R.raw.ok);
mp.start();
while (mp.isPlaying()) {
// donothing
};
mp.release();
this gives me Force Close error, am i missing anything? or do i need to provide the permission in manifest file?..Please help.
Thanks

after created media player you have to call prepare() before start. Try this code
MediaPlayer mp = MediaPlayer.create(this, R.raw.ok);
mp.prepare();
mp.start();

Try with this and see.
public void audioPlayer(String path, String fileName){
//set up MediaPlayer
MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(path+"/"+fileName);
} catch (IllegalArgumentException 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();
}
Change this method according to your code. Also if there is any error, you should post the error log so that others could identify the exact issue.

RTSP streaming doesn't work

I've created an app which will play from on RTSP:
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try
{
mediaPlayer.setDataSource(
"rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov");
mediaPlayer.prepare();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
Toast.makeText(MyYouTubeActivity.this,
"Eror Play", Toast.LENGTH_SHORT).show();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mediaPlayer.start();
But it's not working, in Logcat I see this:
09-12 12:57:20.899: ERROR/PlayerDriver(95): Command PLAYER_PREPARE completed with an error or info PVMFFailure

First inset permission ::
android.permission.WRITE_EXTERNAL_STORAGE
android.permission.INTERNET
code ::
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setDataSource("url");
player.prepare();
player.start();
and also refer :: This

Known streaming mp3 link, Correct Android Version. What is wrong with streaming?

I'm using Android 2.3, so according to this post: Streaming Audio from A URL in Android using MediaPlayer? streaming should work. I'm using a proven mp3 stream from kexp.org.
05-19 13:29:17.141: INFO/StagefrightPlayer(68): setDataSource('http://kexp-mp3-1.cac.washington.edu:8000')
05-19 13:29:17.141: INFO/AwesomePlayer(68): prepare was cancelled before doing anything
try {
mp = new MediaPlayer();
mp.reset();
mp.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.setDataSource("http://kexp-mp3-1.cac.washington.edu:8000");
mp.prepareAsync();
} catch (IllegalArgumentException 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();
} finally {
if(mp!=null) {
mp.release();
mp =null;
}
}

Try this:
MediaPlayer.setDataSource() and prepare() not working - android
