Project Tango Unable To Instantiate Activity - project

Question

Application used to work on older software revisions, but now crashes on startup. My guess is that this isn't a problem with Unity, since I can easily work with other projects, but an issue with wither my device or how I have things set up in the editor. Any help is appreciated! Here is the error I am receiving:
