Android developers can also utilize MediaPlayer to control playback of audio/video files
and streams. The table 6.2 below shows the public methods of MediaPlayer that are com-
monly used in programming.
Method

Description

create()

Creates a MediaPlayer for a given resource id.

start()

Starts or resumes the playback. Successful invoke of this method in a val-
id state transfers the object to the Started state. Calling this method in an
invalid state transfers the object to the Error state.

pause()

Pauses the playback. Successful invoke of this method in a valid state
transfers the object to the Paused state. Calling this method in an invalid
state transfers the object to the Error state.

stop()

Stops playback after playback has been stopped or paused. Successful in-
voke of this method in a valid state transfers the object to the Stopped
state. Calling this method in an invalid state transfers the object to the Er-
ror state.

release()

Releases resources associated with this MediaPlayer object. After re-
lease(), the object is no longer available.

isLooping()

Checks whether the MediaPlayer is looping or non-looping.

setLooping()

Sets the player to be looping or non-looping. Successful invoke of this
method in a valid state does not change the state. Calling this method in
an invalid state transfers the object to the Error state.

isPlaying()

Checks whether the MediaPlayer is playing. Successful invoke of this
method in a valid state does not change the state. Calling this method in
an invalid state transfers the object to the Error state.
