<activity
android:name="path.youractivity"
android:configChanges="orientation|screenSize"
android:screenOrientation="landscape"/>
I have confusion about your Activity
orientation so if you want to go with portrait
then set the screenOrientation
as portrait and for landscape
set landscape
Try this way to setting the fixed orientation
I have updated I think it just because of screen size changed during orientation of activities. This was more affected from 4.0 I think so, Add this screensize
in orientation and then test it
