- One free Play app (com.locphamtran.recipescamera) with an expo-iap PRO
unlock, replacing the paid apk for the store channel
- Android SEND/SEND_MULTIPLE share target feeds photos into the editor,
on cold start and on resume
- BACK button in the TopBar and press-and-hold PEEK replace the chip row
- NOISE REDUCTION and SHARPENING accept -10: a negative SHARPENING softens
the frame before the grain pass, a negative NOISE REDUCTION re-grains it,
in the Skia engine, the live preview and the Kotlin export path alike
- FRAME tab now pinches the whole view (frame + photo + watermark) in both
camera and library; one finger pans that view. Preview only: the exported
file is identical at 1x and while the view is magnified.
- Watermark pinch/drag stay relative and keep priority while the WATERMARK
row is open, so they still work after returning from the FRAME tab.
- Exports go through a native MediaStore insert into DCIM/Camera, falling
back to expo-media-library when the native save fails.
HyperOS Gallery reads EXIF 0x889e (a JSON blob) to build its watermark
frame; without it a photo fails with "cannot recognize the parameters".
CameraX/HAL never supplies that vendor tag, so a capture from this app
lacked it while a stock-camera photo carried it.
Read back the same props the stock camera derives the blob from
(ro.product.device / ro.product.marketname / Build.MANUFACTURER) via the
native module, synthesize the blob in exifWrite, and write it only when
the source has none and the device is Xiaomi/Redmi/POCO - a source blob
is never overwritten.
Local Kotlin module modules/recipescam-export (autolinked via expo ./modules)
exposes decodeEncodeAsync — BitmapFactory decode -> JPEG q95 encode -> file,
all on Dispatchers.IO off the JS/main threads. EXPO_PUBLIC_BENCH=1 builds run
src/dev/nativeBenchProbe.ts: 3 timed decode+encode passes on the bundled
wallframe artwork plus a JS-timer gap check proving the JS thread never
blocks during native rendering. Legacy Skia engine untouched (reference).
