SoundPool crashes in two scenarios. Code for first scenario crashes

@Ian G. Clifton Here is the code for the first type of soundpool I tried. when the button to load the activity the program FCs back to the previous activity.

code starts here but it doesn't transfer over::::::

public class SoundManager {

    private  SoundPool mSoundPool; 
    private  HashMap<Integer, Integer> mSoundPoolMap; 
    private  AudioManager  mAudioManager;
    private  Context mContext;


    public SoundManager()
    {

    }

    public void initSounds(Context theContext) { 
         mContext = theContext;
         mSoundPool = new SoundPool(16, AudioManager.STREAM_MUSIC, 0); 
         mSoundPoolMap = new HashMap<Integer, Integer>(); 
         mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);          
    } 

    public void addSound(int Index,int SoundID)
    {
        mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1));
    }

    public void playSound(int index) { 

         int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
         mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f); 
    }

    public void playLoopedSound(int index) { 

         int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
         mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, -1, 1f); 
    }

}

I found My problem. It is not a problem with these parts of the code. Actually Chirag Shah led me to the answer by his sudgestion. I looked through my code and found that I had locked the buttons out of the create section of the code in the previous activity.

I had

Private Button button1;

This was before the oncreate method but when I removed the private part.

Button button1;

now it works fine.

May this help about :
