Soundpool not looping in android 4.3

sounds not playing with mediaplayer after playing some sounds

I'm developing an android application which is collection of 100 sound effects.
After I play for instance 25 of the sounds, I can't play anymore and I have to close the application and wait for some minutes then open the application and now I can play other sounds.
final MediaPlayer mp81 = MediaPlayer.create(MainActivity.this, R.raw.a81);
I play the sound using the below code:
mp81.start();
I stop the playing sound using the below code:
mp81.seekTo(0);
I also used stop() method but the problem were still existing.
is there any other method i have to add?

Please note: consider using SoundPool for playing short sounds.
Regarding your use-case: you initialize your MediaPlayer instance using the static create() method which means you create a new MediaPlayer object for each sound instead of reusing an existing instance and just changing the data source. This might negatively affect the performance of your app. I suggest that you create an array of paths to your sounds and then instantiate the MediaPlayer like this:
MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(yourArray[x]);
mp.prepare();
mp.start();
} catch(Exception e){
e.printStackTrace();
}
Consult the MediaPlayer Document for more information.

Android : how to play multiple audios using single media player object

I need to create only one media player object Mediaplayer mp = new Mediaplayer();
Using this I need to play multiple audio files one after the other for that i am using handler
and getting the duration.
If i create multiple media player objects it shows error(1, -17)
I also need to display images related to audio files.

Did you rule out SoundPool?
http://developer.android.com/reference/android/media/SoundPool.html
It typically good for short audio clips.

Implement the OnCompletionListener and register it with your MediaPlayer instance.
After the media has been played out it will call this callback method onCompletion
void onCompletion(MediaPlayer mp){
//Here you stop it.
mp.stop();
//Reset the data source path to the new file
mp.setDataSource(<uri>);
mp.prepare(); // or mp.prepareAsync();
// start the mediaplayer after the prepare has completed.
}
Release the mediaplayer instance once you are done playing all the files.
