I have an activity with locked orientation
<activity
android:name=".AboutActivity"
android:screenOrientation="portrait"></activity>
How i can know when user change device orientation?
Maybe question is too unclear, so i try explain what i want in result.
I want to know when user rotate phone AND AFTER THAT rotate layout and other views with my own animation.
I think i can use SensorManager, but maybe exist more elegant way?
