Solve it my self after research:
Problem in Android Manifest configuration
<activity
android:launchMode="singleTop"
android:name=".VideoScreen"
android:screenOrientation="landscape"
android:configChanges="keyboardHidden|orientation"
android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen" />
In above configuration for "Video Screen" activity, android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"
is not supported in full screen with VideoView.
Google TV OS is available with 3.2 OS, So In 3.2 OS for Full Screen used android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen"
and set minimum SDK Version <uses-sdk android:minSdkVersion=11" />
