i already checked my layout file because it says "...InflateException: Binary XML file line #27..." but i didn't find a mistake.

     is needed to present your content, e.g. VideoView, SurfaceView,

Answer 1

I think you are getting error because of this line

  android:textAlignment="center"

which is used in TextView. I have copied your xml layout. and Eclipse showing me error saying there is no resource identifier for textAlignment in the package android.

remove android:textAlignment="center" attribute from TextView and try once...
