Question 2

When I click on the debug icon in Android Studio, I get this NullPointerException from R8.

But...

When I try to investigate further by running gradlew from the command line, there are no reported errors.

./gradlew :app:assembleDebug

Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/5.4.1/userguide/command_line_interface.html#sec:command_line_warnings

So I'm at a loss for how to proceed. This is a commercial media app that had passed beta testing and was supposed to be released... but now this has me stymied.

Things I've tried so far...

clean and rebuild
File -> Invalidate Caches & Restart
Wiping project .gradle and user/.gradle caches, clean and rebuild
enableMultiDex = true in the gradle.config
Increasing JVM memory from 2MB to 4MB
Rebooting the computer

Questions

How to resolve this exception and get un-stuck?
Is it my code or an R8 bug?
Why can't I reproduce the error from the command line?
Is Android Studio running gradle with extra flags its not reporting?
