Specialization of android-emulator-harness for CAMERA / segmentation testing: get a real PERSON in front of the emulator camera so MediaPipe / ML Kit selfie segmentation produces an actual mask, then verify background-replacement / blur / shader effects and tune mask threshold by vision. Use when the task is "test the mask", "verify segmentation", "tune mask threshold", "check a camera/background effect on Android", or any time an app must SEE a human through the emulator camera without a…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Camera / Mask Testing: specialization of android-emulator-harness **Read `android-emulator-harness` first.** That base covers KVM, AVD creation, headless boot, app install/launch, Maestro driving, logcat/screenshot assertion, and teardown. This skill changes only what's needed to put a segmentable human in the camera and run GPU segmentation. Everything else (drive with Maestro, assert on logcat + screenshot) is identical to the base. This skill ships one fixture: **`fixtures/person-framed.png`**, a full-body subject pre-positioned for the emulator's camera-feed crop (see override 3). Feed it directly, or swap in your own subject framed the same way. ## The three camera-specific overrides (each cost real debugging time) 1. **Use a 32-bit `x86` system image, NOT the base's `x86_64`.** MediaPipe Tasks Vision ships `libmediapipe_tasks_vision_jni.so` for `arm64-v8a`, `armeabi-v7a`, and `x86`, **not `x86_64`**. On x86_64 it fails with `UnsatisfiedLinkError` and segmentation silently falls through to the raw frame. API 30 is the highest 32-bit x86 `google_apis` image. Verify in the APK: `unzip -l app.apk | grep mediapipe` (expect a `lib/x86/…` entry). ```bash …

How to install
mdr add simiancraft/simiancraft-skills/android-emulator-mask-testing@sha256:b3a1f878a0996b8eThe line at the top of this page pins the label git:20260602.c098b0e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
