Need help for running video file in Android

Hi, i have problem on running my video files in Android. Im using adobe flash cs6 and AS3 for interface and export all files to my android ( save in APK file ). Videos playing well but i was wondering isnt possible for my videos to be played in full screen mode when full screen button is clicked ?  Previously, when i clicked full screen button in provided skin, the video size still remain same, just it shows video screen, not full screen. Anyone knows how to fix this ? or maybe coding for as3 might works ? i'd try every possible ways but none works. Appreciate any helps,thanks !
