PagerAdapter start position

I've found a way to set it's position, which is done outside of the class:

 awesomePager = (ViewPager) findViewById(R.id.awesomepager);
 awesomePager.setAdapter(awesomeAdapter);
 awesomePager.setCurrentItem(CurrentPosition);

and it can be limited by calculating the amount of items I want to fit in to it

I have noticed that if you recreate Activity (orientation change) with ViewPager having FragmentStatePagerAdapter, then the Adapter will reuse it's Fragments. The way to stop it is:

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    if (viewPager != null) {
        // before screen rotation it's better to detach pagerAdapter from the ViewPager, so
        // pagerAdapter can remove all old fragments, so they're not reused after rotation.
        viewPager.setAdapter(null);
    }
    super.onSaveInstanceState(savedInstanceState);
}

but then after Activity recreation ViewPager alwayes opens page 0 first and setCurrentItem(CurrentPosition); doesn't work. Fix for that is changing page after delay:

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        viewPager.setCurrentItem(newPosition);
    }
}, 100);

To start with the last fragment I did this:

PagerAdapter pagerAdapter = new PagerAdapter();
viewPager.setAdapter(pagerAdapter);
viewPager.setCurrentItem(pagerAdapter.getCount() - 1);
