Device compatibility (regression fix):
- The CAMERA permission (from zxing_barcode_scanner / image_picker) implicitly
required android.hardware.camera, excluding camera-less devices — Play showed
Automotive -96%, Chromebook -86%, TV -25%. Declare camera & location
uses-feature required="false" to keep those devices supported.
- Detect a real camera at runtime (PackageManager.FEATURE_CAMERA_ANY via the
existing MethodChannel), cache it at bootstrap, and hide the QR scan button and
the camera photo-source option when absent, so no broken actions are offered.
Play "app optimization" recommendations:
- Enable R8 (isMinifyEnabled + isShrinkResources) with keep rules for the
OCR (tesseract4android), SQLCipher and notifications JNI/reflection code.
- Bitmap downscaling: cacheWidth/cacheHeight (and ResizeImage for avatars) on
list thumbnails and avatars so photos decode to on-screen size, not full res.
- Edge-to-edge: opt in with transparent system bars in main().
Release flow:
- Tagged builds now publish to the production track at 100% (was internal);
add a manual deploy_internal lane as a QA safety net.
- Document country/region availability as a Play Console setting (not in-repo).
