So check out this lovely error. Periodically I pull an update to the Android project I work with and I get an error like this. Sometimes the trick to this (the error doesn't explain this) is Tools->AGP Upgrade Assistant. But sometimes it means you need to upgrade Android Studio. To what? Error doesn't say. What I have to do is go on project chat and say "what version are we using now?". Then they say the name of an animal, like "hummingbird", and I have to work out what version # that is in Snap
