    copied!<p>I have viewpager with some fragments and i set to each fragment my model class according which UI of fragment should be edited. That model class i set to fragment at constructor before i add that fragment to FragmentStatePagerAdapter. My problem is that after rotating screen or when system kills my application and i restore it, my fragment are recreated by system and my model class instance is lost. Even if I set new FragmentStatePagerAdapter, fragments created by system are visible. Is there any right way of achive that i create new instances of my fragments and place them into viewpager? I tried so many thinks like removing fragments from FragmentManager, adding Adapter to viewpager again, change FragmentStatePagerAdapter only to FragmentPagerAdapter and nothing helped.</p> <p>My activity class with loading model classes in loader from some resource:</p> <pre><code> List&lt;Fragment&gt; visibleFragment = new ArrayList&lt;Fragment&gt;(); for (Screen screen : wizard.screens) { if (screen.visible) { visibleFragment.add(new ScreenUI(screen)); } } viewPager.setAdapter(null); viewPager.setAdapter(new WizardPagerAdapter(getSupportFragmentManager(), visibleFragment)); </code></pre> <p>My FragmentStatePagerAdapter</p> <pre><code>public class WizardPagerAdapter extends FragmentPagerAdapter { private final List&lt;Fragment&gt; mFragments; private final int count; public WizardPagerAdapter(FragmentManager fm, List&lt;Fragment&gt; fragments) { super(fm); mFragments = fragments; count = mFragments.size(); } @Override public Fragment getItem(int index) { return mFragments.get(index); } @Override public int getCount() { return count; } } </code></pre>
