Android support library onActivityResult() bug fix for nested fragments

SupportChildFragmentActivityResult.java

@Override
public void startActivityForResult(Intent intent, int requestCode) {
    if (getParentFragment() != null) {
        getParentFragment().startActivityForResult(intent, requestCode);
    } else {
        super.startActivityForResult(intent, requestCode);
    }
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // notifying nested fragments (support library bug fix)
    final FragmentManager childFragmentManager = getChildFragmentManager();

    if (childFragmentManager != null) {
        final List<Fragment> nestedFragments = childFragmentManager.getFragments();

        if (nestedFragments == null || nestedFragments.size() == 0) return;

        for (Fragment childFragment : nestedFragments) {
            if (childFragment != null && !childFragment.isDetached() && !childFragment.isRemoving()) {
                childFragment.onActivityResult(requestCode, resultCode, data);
            }
        }
    }
