Android - hiding ActionBar icon and title during launch

I was developing an app that had a tabbed interface (FragmentPagerAdapter) inside the main activity. Each tab was setting different ActionBar icon and title inside onTabSelected method. Something like this:

 
@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
   viewPager.setCurrentItem(tab.getPosition());
   if (tab.getPosition() == 0){
      actionBar.setTitle("title1");
      actionBar.setIcon(R.drawable.icon1);
   }
   if (tab.getPosition() == 1) {
      actionBar.setTitle("title2");
      actionBar.setIcon(R.drawable.icon2);
   }
   if (tab.getPosition() == 2) {
   actionBar.setTitle("title3");
   actionBar.setIcon(R.drawable.icon3);
}
}
 

This was working fine when the app was running and resuming from paused. But on the initial launch, global application icon and title was appearing inside ActionBar for half a second or so, before being overridden by the code in onTabSelected .
