playing a video in unity3d

Hi

I am trying to play a video in unity3d but wen i build and run my project it gives me an error saying "com.qualcomm.qcarUnityPlayer/com.unity3d.Player.VideoPlayer" Activity not found in androidmanifest.xml

Can anyone please give me a solution for this?

if(play_video) { iPhoneUtils.PlayMovie("videoname.extension",Color.black, iPhoneMovieControlMode.Hidden);

}

it will work for both android as well as ios

i have done the same thing through button press using..

if (GUI.Button (Rect (20,155,200,25), "ControlMode.Hidden")) { iPhoneUtils.PlayMovie(selectedVideo, Color.red, iPhoneMovieControlMode.Hidden); //Debug.Log("Movie-ing"); }

but it is giving an error as "com.qualcomm.qcarUnityPlayer/com.unity3d.Player.VideoPlayer" Activity not found in androidmanifest.xml

i am not getting wat the problem is.. do i have to make some changes in my androidmanifest.xml file ?
