Root cause: TWA LauncherActivity.onCreate calls Bitmap.createBitmap on the
splash drawable — the XML layer-list with only a color fill had 0x0 intrinsic
dimensions, causing IllegalArgumentException: "width and height must be > 0".
Fixes:
- Replace splash.xml with splash.png (384x384 blue circle with P logo)
- Add proper PNG launcher icons at all 5 density buckets (mdpi through xxxhdpi)
- Change android:icon from @drawable to @mipmap for proper icon resolution
The TWA LauncherActivity crashed with Resources$NotFoundException (0xffffffff)
because android:value with hex color strings is not supported by
androidbrowserhelper — it expects android:resource pointing to color resources.
- Created res/values/colors.xml with all app colors
- Changed AndroidManifest.xml to use android:resource="@color/..."
- Updated styles.xml to reference color resources
- APK: Add WAKE_LOCK, BOOT_COMPLETED, ACCESS_NETWORK_STATE permissions
- APK: Disable allowBackup for medical data security
- APK: AudioRecordingService now acquires wake lock, has stop action in notification
- Serve /.well-known/assetlinks.json for TWA domain verification
- Service worker: cache app shell, stale-while-revalidate for assets, network-first for API
- Admin model management: validate model ID format, prevent built-in conflicts, audit toggle actions, prevent disabling all models
- Bump version to v9.0.0, Docker tag to v9
