Add a pull-request status check across API 33-37
Runs the JVM tests and the instrumented suite on every pull request to main, with one emulator job per supported API level. The matrix is the whole range rather than a single level because the foreground-service type differs across it -- none below 34, dataSync at 34, mediaProcessing from 35 -- so testing one level would leave two thirds of that branch unexercised. Running the range locally is what caught a test that had baked in an assumption about the host's encoders. API 37 needs its image level stated separately. It is published as android-37.0, not android-37, so a plain integer resolves to nothing and the image download silently finds no package. FFmpeg is built once and shared. The AAR is not committed -- 35 MB of native code, and F-Droid strips checked-in binaries -- but every job needs it, since the app compiles against it and the instrumented tests exercise it for real. Building it is a full cross-compile of FFmpeg, x264, x265 and SVT-AV1, so it is cached on the contents of tools/ffmpeg, which is what actually determines the output. The job also asserts the AAR carries native libraries for both ABIs: a truncated or stub archive would otherwise pass a file-exists check and send the matrix off to fail confusingly five times over. fail-fast is off. Knowing whether a failure is universal or specific to one API level is most of the diagnosis. build.yml no longer runs on pull requests. It triggered on every PR with no branch filter, so both workflows would have run, and its unit job falls back to a stub AAR -- a weaker check that could mask a compile break the real one would catch. It keeps its post-merge and release duties. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
