onPageSelected isn't triggered when calling setCurrentItem(0)

Question

I have an Activity with a ViewPager which displays a bunch of pictures. When it starts the ViewPager\'s position is set based on what the user selected in a previous Activit

Answer 1

onPageSelected is not triggered for page which is opened first. For this case I manually perform all needed actions. Also, I suppose that call to onPageSelected(0) should work too.
