Description
[REQUIRED] Environment info
firebase-tools: 9.23.1
Platform: macOS 11.6.1
[REQUIRED] Test case
With apologies, it is not that easy to provide a minimal complete example of App Check on Android causing the database emulator to hang. At least the minimal part. But please bear with me, I'm the maintainer of react-native-firebase so we have a fully reproducible end-to-end test harness that shows this.
I've prepared a branch in our repository that is fairly focused so reproduction is quick:
To set things up you want to clone that, then follow the steps in our test harness README - https://github.com/invertase/react-native-firebase/blob/master/tests/README.md
(they boil down to: yarn, yarn tests:android:build, create an android emulator called "TestingAVD" and start it, yarn tests:emulator:start to start the firebase emulator, yarn tests:packager:jet to start our test bundler then you are ready)
[REQUIRED] Steps to reproduce
After doing the above things, run yarn tests:android:test, it will start our e2e harness but I've boiled it down to just app-check running then the database tests. It will fail almost immediately - just hanging the first time it tries to hit the database emulator (to do a server increment, for what it's worth, but it fails on all access that I saw?)
[REQUIRED] Expected behavior
It rolls right through the database tests like it used to
it pass all tests if you comment line 47 of tests/app.js (so it goes against live database).
Note that if you do yarn tests:ios:pod:install (assuming you have cocoapods installed?) and then yarn tests:ios:build and yarn tests:ios:test, iOS + app check + database emulator has no problem.
Seems android specific. Javascript is untested.
[REQUIRED] Actual behavior
Hangs on first attempt to access database emulator after including app check library.

I'd be happy to collaborate if there's anything I can do to help put a spotlight on this but (despite the size of our e2e test suite when considered as a "reproducible example") I think this repro is about as clean as I can make it
