Unexpected problem when unmounting #82
Comments
I have a very similar Anvil issue after switching from Android SDK 23 to 25. When unmounting a RecyclerView, a NullPointerException is thrown. Because the RecyclerView was already detached from the window once and Anvil tries to detach it again. First stack trace:
Second stack trace (causing the exception):
Seems like Android itself takes care of removing the Anvil views and Anvil tries to do it a second time. Not sure what would be the cleanest solution here. |
I've got this error reported from an app in production and it seems that it tried to remove view more than once. Maybe a simple try/catch on L138 would solve with no side effects.
