in the SD card.
and it continue to play these 2 video files until user touch the
screen then it will quit this activity.
At the beginning, The media player these 2 video files very well (no
error), however when it play several times of the 2 video file, then
MediaPlayer server was died. it throws an exceptions"
Java.io.exception: setDataSource error 0x800000... and I quit my
application, use Android device itself Video Player to play any video
files in the SD card, but it doesn't work too. shows Media Server
Error Dialog.
I spent a whole day to check my application, but got no result.
Attached is my source code, any body can help me?
