| # Compiles all app Kotlin (by building the debug APK) on PRs that change Kotlin | |
| # source, to catch Kotlin compile breaks before they reach main. The full signed | |
| # release build (build-android.yml) is workflow_call-only and never runs on PRs, | |
| # so without this gate a Kotlin break (e.g. the bare success() call in #8754) | |
| # could merge undetected. | |
| # | |
| # Scope: the PR trigger covers Kotlin (*.kt) and shared CI setup changes. It | |
| # does NOT run on Go/gomobile-AAR or Flutter/dep changes — a Go change that | |
| # breaks the AAR<->Kotlin interface would surface in build-android.yml / | |
| # release, not here. workflow_dispatch exists only for benchmarking/debugging. | |
| # | |
| # Debug build only: no keystore/APP_ENV secrets, no AAB, no artifact upload. | |
