title: Android Tabbed layout
body: <p>This thread was probably raised many, many times, but i still haven't found any solution how to create simple tabbed layout, like Google Play app got one, which could work for me (deprecated classes/functions, or i receive errors which i couldn't understand).
  Can someone please answer me with some links maybe or short explaination?
  As far a i understand, i need actionBar in my mainActivity and 2 seperate activities (i want only 2 tabs, its training only) which are active at the same time. Correct me if i'm wrong</p>
