Solution 1:

Since you don't need any kind of caching, it's probably a good idea for you to use viewPager.setOffscreenPageLimit(0) so pages won't be loaded in background, and onResume will be called only when page is actually displayed.UPD: Thanks, Yarh, for pointing out that setOffscreenPageLimit(0) doesn't work.

If this doesn't work for you, use viewPager.addOnPageChangeListener(listener) - onPageSelected(position) method should help.

use onTabSelected and onTabReSelected methods of navigation tabs to do your stuff
