Create a media player

To play audio on a BlackBerry® device, use the Mobile Media API to create a media player and then add

functionality to it.

Task Steps

sequence of tones.

> Use the ToneControl to permit playback of a BlackBerry device user-defined sequence of tones in an

unvarying pitch.

Tempo is the bpm with 1 beat equal to 1/4 note. You determine the tempo by multiplying the tempo

modifier by 4 to keep it within the byte range of 1 to 127. Tempos in the range of 20 bpm to 508 bpm equate

to a tempo modifier range of 5 to 127.

Create a player for media

from a URL.

>Invoke Manager.createPlayer(String locator). The string must use URI syntax that describes

the media content.
