GeoQuiz has stopped Chapter 3

Good afternoon everyone this is my first post here. I’m running into some kind of issue with the very start of Chapter 3. I have no errors in my code, but the app won’t run on the emulator. All I get are “GeoQuiz has stopped” messages. I feel that there is something wrong with my coding with the onStart, onResume, onPause lifecyles, but I cannot find the issue.
