Yeah there's something you need to know about SoundPool: Init well
before playing - that is, you need to know way ahead of time what
sounds you will be using because it doesn't work well to play
immediately after initializing. I think they attempt to initialize
asynchronously or something because I had problems when I tried to
load and play back to back like you're trying there.
When I use SoundPool, I load everything upon creation of the instance
of the game then trigger the plays whenever I need them. Here's my
current code for SoundPoolSoundManager:
public class SoundPoolSoundManager implements SoundManager {
private static final String TAG = "SoundPoolSoundManager";
public static final int SOUND_1 = 1;
private boolean enabled = true;
private Context context;
private SoundPool soundPool;
private HashMap<Integer, Integer> soundPoolMap;
public SoundPoolSoundManager(Context context) {
this.context = context;
}
public void reInit() {
init();
}
public void init() {
if (enabled) {
Log.d(TAG, "Initializing new SoundPool");
//re-init sound pool to work around bugs
release();
soundPool = new SoundPool(SOUNDPOOL_STREAMS,
AudioManager.STREAM_MUSIC, 100);
soundPoolMap = new HashMap<Integer, Integer>();
soundPoolMap.put(SOUND_1, soundPool.load(context,
R.raw.sound1,
1));
Log.d(TAG, "SoundPool initialized");
}
}
public void release() {
if (soundPool != null) {
Log.d(TAG, "Closing SoundPool");
soundPool.release();
soundPool = null;
Log.d(TAG, "SoundPool closed");
return;
}
}
public void playSound(int sound) {
if (soundPool != null) {
Log.d(TAG, "Playing Sound " + sound);
AudioManager mgr = (AudioManager)
context.getSystemService(Context.AUDIO_SERVICE);
int streamVolume =
mgr.getStreamVolume(AudioManager.STREAM_MUSIC);
Integer soundId = soundPoolMap.get(sound);
if (soundId != null) {
soundPool.play(soundPoolMap.get(sound),
streamVolume,
streamVolume, 1, 0, 1f);
}
}
}
public void setEnabled(boolean enabled) {
this.enabled = enabled;
}
}
