In case anybody else stumbles upon this issue.

Use the example app within app-auth android github project. Don't use Google CodeLabs app-auth example! The code from the question above is from Google CodeLabs, it is very old and no longer works (state at July 2020). I did the same mistake, app-auth links codelabs on their own page/readme, so I started using codelabs code and ended up with lots of problems and errors.

The new app-auth version 0.7.x uses a json configuration file and the example app shows how to handle errors around pending intents etc. .
