Method Detail

getVolume

public int getVolume()

Get the current volume of the sound, between 0 (off) and 100 (loudest.)

isPlaying

public boolean isPlaying()

True if the sound is currently playing.

pause

public void pause()

Pauses the current sound if it is currently playing. If the sound is played again later, it will resume from the point where it was paused.

Make sure that this is really the method you want. If possible, you should always use stop(), because the resources can be released after calling stop(). The resources for the sound will not be released while it is paused.

playLoop

public void playLoop()
