Refresh images on FragmentStatePagerAdapter on resuming activity

I have created an activity that uses `FragmentStatePagerAdapter` to provide small gallery. However, I can't get it to refresh when activity resumes (after coming back from other activity, for example). Every time first two pictures will be blank, and only after i swipe two pictures to the side, they get refreshed. None of the answers I've found work (especially overriding `getItemPosition()`) I set it up like this: ``` mPagerAdapter = new PhotosPagerAdapter(getSupportFragmentManager()); mPager = (ViewPager) findViewById(R.id.photosViewPager); mPager.setAdapter(mPagerAdapter); ``` Then I have FragmentStatePagerAdapter class: ``` private class PhotosPagerAdapter extends FragmentStatePagerAdapter{ public PhotosPagerAdapter(FragmentManager fm) { super(fm); } @Override public int getCount() { return photos.size(); } @Override public Fragment getItem(int position) { ImageFragment f = new ImageFragment(position); return f; } @Override public int getItemPosition(Object object) { throw new RuntimeException(); //return POSITION_NONE; } } ``` As you probably noticed, I throw RuntimeException in getItemPosition, because I wanted to check when it's called. And it isn't called until I add something to list containing my pictures. Then ImageFragment class: ``` public class ImageFragment extends Fragment{ int position; Bitmap mBitmap; int width; int height; ImageView img; public ImageFragment(){ } public ImageFragment(int position){ this.position = position; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { img = new ImageView(container.getContext()); img.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); width = container.getWidth(); height = container.getHeight(); loadBitmap(); return img; } public void loadBitmap(){ if (img == null){ return; } final BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeFile(photos.get(position), options); options.inSampleSize = calculateInSampleSize(options, width/2, height/2); options.inJustDecodeBounds = false; mBitmap = BitmapFactory .decodeFile(photos.get(position), options); img.setImageBitmap(mBitmap); } @Override public void onDestroyView() { mBitmap.recycle(); super.onDestroyView(); } } ``` Code is kinda messy after I tried to fix it... But: removing `onDestroyView()` doesn't work. I have put `mPagerAdapter.notifyDataSetChanged()` in several places that must be called (like `onResume()`), with no result. I'm getting kinda desperate with that.
