Thanks for your report. I cannot replicate it, but tried to fix it blindly. Please try to update to version 0.2.3.

FragmentManager fm = getSupportFragmentManager(); List fragmentList = fm.getFragments(); if (fragmentList == null || fragmentList.size() == 0) return false; Fragment fragment; List removedIndices = new ArrayList<>(); int size = fragmentList.size(); for(int i = 0;i < size;i++) { fragment = fragmentList.get(i); if (fragment == null) { removedIndices.add(i); } } int removedIdx; for (int i = removedIndices.size() -1; i >= 0;i--) { removedIdx = removedIndices.get(i); fragmentList.remove(removedIdx); } boolean result = super.onBackPressedWithResult(); size = removedIndices.size(); for (int i = 0; i < size;i++) { removedIdx = removedIndices.get(i); fragmentList.add(removedIdx, null); } I was doing this in my base fragment onBackPressedWithResult(); which became useless now :) thank you
