Android: sound pool and service

Question

I created a service that implements a media player class to play music in the background. But now I want to convert to a sound pool so that I can play several sounds. can help anyone who can provide me with a link to the source code?

Thanks at Advance.

Answer 1

I just implemented a service with background sound, I checked the code http://android-er.blogspot.com/2010/11/play-audio-resources-using-soundpool.html and http://developer.android.com/guide /topics/fundamentals/bound-services.html

public class LocalService extends Service { // Binder given to clients private final IBinder mBinder = new LocalBinder(); // Random number generator private final Random mGenerator = new Random(); private SoundPool soundPool; private HashMap<Integer, Integer> soundsMap; int SOUND1=1; int SOUND2=2; @Override public void onCreate() { // TODO Auto-generated method stub super.onCreate(); soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 100); soundsMap = new HashMap<Integer, Integer>(); soundsMap.put(SOUND1, soundPool.load(this, R.raw.baby_laugh, 1)); soundsMap.put(SOUND2, soundPool.load(this, R.raw.touchdown, 1)); } public void playSound(int sound, float fSpeed) { AudioManager mgr = (AudioManager)getSystemService(Context.AUDIO_SERVICE); float streamVolumeCurrent = mgr.getStreamVolume(AudioManager.STREAM_MUSIC); float streamVolumeMax = mgr.getStreamMaxVolume(AudioManager.STREAM_MUSIC); float volume = streamVolumeCurrent / streamVolumeMax; soundPool.play(soundsMap.get(sound), volume, volume, 1, 0, fSpeed); } /** * Class used for the client Binder. Because we know this service always * runs in the same process as its clients, we don't need to deal with IPC. */ public class LocalBinder extends Binder { LocalService getService() { // Return this instance of LocalService so clients can call public methods return LocalService.this; } } @Override public IBinder onBind(Intent intent) { return mBinder; } /** method for clients */ public int getRandomNumber() { return mGenerator.nextInt(100); } public void soundPlay(int index){ playSound(index, 1.0f); Log.d("SOUND1","hi1"); } } 

you call from Activity using

 public class Test extends Activity implements OnClickListener { LocalService mService; boolean mBound = false; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button btn=(Button)findViewById(R.id.a_button); btn.setOnClickListener(this); } @Override protected void onStart() { super.onStart(); // Bind to LocalService Intent intent = new Intent(this, LocalService.class); bindService(intent, mConnection, Context.BIND_AUTO_CREATE); } @Override protected void onStop() { super.onStop(); // Unbind from the service if (mBound) { unbindService(mConnection); mBound = false; } } /** Called when a button is clicked (the button in the layout file attaches to * this method with the android:onClick attribute) */ public void onButtonClick(View v) { if (mBound) { // Call a method from the LocalService. // However, if this call were something that might hang, then this request should // occur in a separate thread to avoid slowing down the activity performance. int num = mService.getRandomNumber(); Toast.makeText(this, "number: " + num, Toast.LENGTH_SHORT).show(); } } /** Defines callbacks for service binding, passed to bindService() */ private ServiceConnection mConnection = new ServiceConnection() { public void onServiceConnected(ComponentName className, IBinder service) { // We've bound to LocalService, cast the IBinder and get LocalService instance LocalBinder binder = (LocalBinder) service; mService = binder.getService(); mBound = true; } public void onServiceDisconnected(ComponentName arg0) { mBound = false; } }; public void onClick(View arg0) { if (mBound) { // Call a method from the LocalService. // However, if this call were something that might hang, then this request should // occur in a separate thread to avoid slowing down the activity performance. mService.soundPlay(1); int num = mService.getRandomNumber(); Toast.makeText(this, "number: " + num, Toast.LENGTH_SHORT).show(); } } } 

Thanks to everyone who helps me. Especially for those who write a blog.
