how can I make sure the right layout from the right layout-folder is choosen when I change the orientation while the Activity is running?

Question

I have different layouts for different screen-orientations in my application. The layouts are saved in layout-land and layout-port folders. When I start my Application Android choose the right orientation for the first Activity (Loadscreen in my case) but when I change the orientation of my phone after starting the first Activity Android doesn't change to the layout from the other orientation folder. How can I make sure the right layout get's selected if I change the orientation during the Activity runtime? Is there an OnOrientationChanged Method or something like that?

Remove this

android:configChanges="keyboardHidden|orientation|screenSize">

The default behaviour of android is to create a new object and inflate new layout files when orientation changes but this line of code prevents restarting of your activity when orientation changes and hence the layout in layout-land will be ignored.Read https://developer.android.com/guide/topics/resources/runtime-changes.html
