Android Play video from SD Card | Populating a listview with videos from sdcard in android

Hello Friends,
            This is an android simple example which list all videos file store in 
device sd card and Play it in Video view .
Android provides a view control android.widget.VideoView that encapsulates
creating and initializing the MediaPlayer.
