Android ViewPager setCurrentItem not working after onResume

Ive got this strange issue, ViewPager's setCurrentItem(position, false) works perfectly fine, then im switching to another activity, and after im back to the first activity, the ViewPager always ends up on the first item. Even though ive added setCurrentItem to onResume method it still ignores it. Its not even throwing any exception when im trying to set item to out of bounds index. Though later on when i call this method, when the button "next" is clicked, it works like expected. Checked my code 10 times for any possible calls to setCurrentItem(0) or smth but its just not there at all.Ive got this strange issue, ViewPager's setCurr
