Hi,
The getDuration() method returns -1 if the MediaPlayer is not yet prepared.
The best way to call the VideoView or MediaPlayer's getDuration() is after
they are prepared, ie. in their onPrepared() call or after that.
This is possible in MediaPlayer in the current SDK and will be possible in
the VideoView in one of the future releases of the SDK. You cannot get the
exact duration in VideoView using the getDuration() method, currently as the
PreparedListener for VideoView is not available. Is the use of duration
mandatory in your application?
Thanks,
Megha
