GeoQuiz Challenge 1 Error

I’m working on adding a Listener to the TextView, but when I go to run my application I run into the following error:

Installation failed with message Failed to finalize session : INSTALL_FAILED_INVALID_APK: Split lib_slice_3_apk was defined multiple times.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.

I don’t how this is possible because I’m working a copy of GeoQuiz (GeoQuiz Challenge). How can I fix this?
