Buggy source:
@Override public void onMapSharedElements(List<String> names,Map<String,View> sharedElements){
  LOG("String_Node_Str",mIsReentering);
  if (mTmpState != null) {
    final int oldPosition=mTmpState.getInt(EXTRA_OLD_ITEM_POSITION);

        names.add(newTransitionName);
        sharedElements.clear();
