SoundPool (Sound Pool) (System API)

The SoundPool module provides APIs for loading, unloading, playing, and stopping playing system sounds, setting the volume, and setting the number of loops.

Before using these APIs, you must call media.createSoundPool to create a SoundPool instance.

NOTE

The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.

This topic describes only system APIs provided by the module. For details about its public APIs, see SoundPool (Sound Pool).
