Waiting for SoundPool to load before moving on with application

package com.example.soundpoolexample;

You can have an elegant solution using Semaphore, however try to avoid blocking onCreate(), since the app will not be responsive, the code here is just to illustrate the use of Semaphore

public class SoundPoolExample extends Activity implements OnTouchListener {

public static final Semaphore semaphore = new Semaphore(0);

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
        @Override
        public void onLoadComplete(SoundPool soundPool, int sampleId,
                int status) {

            semaphore.release();
        }
    });
    soundID = soundPool.load(this, R.raw.sound1, 1);

    // Will block since there is not permits (the semaphore is initialized with 0)
    // then will continue once semaphore.release(); is called i.e. after loading is finished
    semaphore.acquire();
} 

// rest of your class

}
