AudioManager – SoundPool in Android

he sound files played with SoundPool should not exceed 1 MB.SoundPool does load the file asynchronously.

Android supports different audio streams for different purposes. The phone volume button can be configured to control a specific audio stream, e.g. during a call the volume button allow increase / decrease the caller volume. To set the button to control the sound media stream set the audio type in your application.

context.setVolumeControlStream(AudioManager.STREAM_MUSIC);

As of Android API8 it is possible to check if the loading is complete via a OnLoadCompleteListener.

soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {

            @Override

            public void onLoadComplete(SoundPool soundPool, int sampleId,

                    int status) {

                loaded = true;

            }

        });
