I am trying to play sound in android one after from "res/raw" folder. But
it is only playing the first sound from sounds array. is there any other
way to do it?
There is three sound file in raw folder

package com.protonray.calculatorplus;
import java.util.List;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.app.Activity;
public class LayoutNew extends Activity{
int count=0;
int[] sounds={R.raw.aa,R.raw.ma,R.raw.ar };
MediaPlayer mp=new MediaPlayer();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_new);
Button play=(Button) findViewById(R.id.play);
play.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
count =0 ;
//Play the Frist sound
mp =MediaPlayer.create(LayoutNew.this,sounds[count]);
mp.start();
count =1 ;
}
});
mp.setOnCompletionListener(new OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
if(count<3){
mp.stop();
//Play next sound
mp
=MediaPlayer.create(LayoutNew.this,sounds[count]);
mp.start();
count++;
}
}
});
}
}
