This line in manifest doesn't help:

android:configChanges="orientation|keyboardHidden"

And one thing else: in my activity i use custom view (horizontal ListView) from https://github.com/dinocore1/DevsmartLib-Android

The app is working fine without this custom view, but i need to use it.

Answer 1

Unfortunately i don't have enough reputation to post images.

XML files are not images, and layouts are XML files.

I found that if i remove listview from first tab or HorizontalListView from the second, i can change orientation without any problem

That, plus your symptoms, suggests that you named those two widgets with the same android:id value. That will not work, as their saved states are not the same. Either make them be both the same class, or name them something different.
