android - Error(-19,0) Mediaplayer

Question

I am trying to make an app that plays specific sounds on button click , I got like 100 buttons created statically not in an array or anything , and I assigned the sounds to each button correctly the problem is , after playing a number of buttons it gives me that error my questions are

1. Any way I could possibly switch to generic code from this mess
2. Anyway I could stop getting this error and the sounds to continue working on every button whatever the amount of sounds played??

Below is my code :

   package com.example.buttonsdemo;

import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


       Button messageButton_0 = (Button) findViewById(R.id.akali);
       final MediaPlayer mpButtonClick_0= MediaPlayer.create(this,R.raw.akali) ;
       messageButton_0.setOnClickListener(new View.OnClickListener() {

           @Override
           public void onClick(View arg0) {

              mpButtonClick_0.start();
              if(!mpButtonClick_0.isPlaying()){
                 mpButtonClick_0.stop();
                 mpButtonClick_0.release();
              }

     }  
});

And it goes on like this for 100 more buttons or so any help plz

Answer 1

From the error messages, it is clear that a start on MediaPlayer is called when the same is in error state. From your messages,

03-04 16:21:21.925: E/MediaPlayer(5769): stop called in state 0

State 0 corresponds to MEDIA_PLAYER_STATE_ERROR

03-04 16:21:21.925: E/MediaPlayer(5769): error (-38, 0)

The error no. -38 corresponds to INVALID_OPERATION from MediaPlayer::start. Please note that INVALID_OPERATION is set to -ENOSYS which is -38 from errno.h.

You may have to investigate why your MediaPlayer is in an erroneous state.
