That looks to still be using the previous version. Could you upload a minimal sample project using 2.3.0-alpha05 that reproduces your issue?

The sample at #1 should be using 2.3.0-alpha05 out of the box. I do not have a minimal sample at the time, sorry.

That sample was using lifecycle 2.2.0 when I opened it. Upgraded it to 2.3.0-alpha05 and got an ObsoleteLintCustomCheck which is being addressed in this bug.

Gonna close this as not reproducible, and once you get a chance to reproduce it, just upload it here and would be happy to take a look.

Can you try this again: https://github.com/Mygod/VPNHotspot/commit/8674369b5baf7241e734c5ddb4d3f97a19b311c5

You can set environment variable LINT_PRINT_STACKTRACE=true to dump a full stacktrace to stdout.

Also reproducible locally on Android Studio 4.1 beta 3.

Still couldn't make see in the app. But was able to reproduce based on the class throwing the error and get a fix.
