# The debug build, on pushes to main and pulls into it, as test.yml runs.
# That runs the JVM tests and the coverage gate beside this, in a job of
# its own, so neither waits on the other.
#
# The debug build is signed with the SDK's debug key, so it needs no
# keystore and no secret. The release build is not here, for the reason
# test.yml gives: R8 takes about an hour.
#
# Android lint is not here yet: `lintDebug` finds 8 errors in main as it
# is (MissingPermission in GrainMessagingService.kt, and seven of
# ViewModelConstructorInComposable). Once they are fixed, or taken into a
# baseline, it is one more step after the build:
# `./gradlew $GRADLE_FLAGS :app:lintDebug`.
#
# The SDK setup, the image and the memory settings are test.yml's, so the
# two share the SDK and Gradle caches: see there for why each is as it is.
