Re-enable test-android on main once the self-hosted runner is back #379

Context

The test-android job in check.yml runs on ubuntu-self-hosted. That runner is currently offline — the job sits in queued indefinitely (observed 6h+ on 2026-07-18). Because it never starts, the whole Check run on main never completes, which blocks main from ever reporting green.

As a stopgap, the job's if was changed from:

if: github.ref == 'refs/heads/main' || contains(github.event.pull_request.labels.*.name, 'Android 🤖')

to run only on PRs labeled Android 🤖, removing it from main pushes. This means Android is no longer exercised on main automatically.

To re-enable

• Confirm the ubuntu-self-hosted runner is back online (or migrate the job to a GitHub-hosted ubuntu-latest runner with KVM for the emulator).
• Restore the github.ref == 'refs/heads/main' condition on test-android.
• Remove the temporary comment added above the if.

Notes

• Also consider whether the job should be moved off self-hosted entirely to avoid this failure mode recurring — GitHub-hosted Ubuntu runners now support nested virtualization (KVM) for Android emulators.
