SoundPool se bloque dans deux scénarios. Code pour les plantages du premier scénario

Question

@Ian G. Clifton Voici le code du premier type de soundpool que j'ai essayé. lorsque le bouton pour charger l'activité, le programme FC revient à l'activité précédente.

le code

commence ici, mais il ne transfère pas sur ::::::

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); 
    } 

}

Answer 1

J'ai trouvé Mon problème. Ce n'est pas un problème avec ces parties du code. En fait Chirag Shah m'a conduit à la réponse par sa surprise. J'ai regardé mon code et j'ai constaté que j'avais enfermé les boutons de la section de création du code dans l'activité précédente.

j'avais

Private Button button1; 

C'était avant la méthode oncreate mais quand je l'ai enlevé la partie privée.

Button button1; 

maintenant ça marche bien.
