Re: Unable to play media from sdcard

Are you able to play the same file using the built in media player?  Does this happen for any MP3 or just this one?

I am able to play video(.3gp) using the built in media player. but unable to play same video from my code.its throwing Error saying "java.io.IOException:Locator does not reference a valid media file.

Player player = javax.microedition.media.Manager
.createPlayer("file:///SDcard/BlackBerry/videos/747.3gp");
//Dialog.alert("before player.realize()");
player.realize();
VideoControl videoControl = (VideoControl) player.getControl("VideoControl");
Field videoField = (Field)videoControl.initDisplayMode(
VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field" );
add(videoField);
VolumeControl volume = (VolumeControl) player.getControl("VolumeControl");
volume.setLevel(30);
player.start();
