An Android duplicate-photo finder. Pure-Kotlin core (SHA-256 + dHash hashing, exact and perceptual union-find grouping, three sensitivity presets) with MediaStore access, a persistent SQLite hash index and a tiered ScanEngine behind a Jetpack Compose UI. No INTERNET permission, no ads, no analytics, no account. Ships versionCode 2 / versionName 1.0.1, carrying the scan-stall hardening (BoundedCall breaker) and verified against a 5,363-photo device library. 80 JVM unit tests, lint clean. Release paperwork is in docs/ (Play checklist, store listing, edge-case testing), the upload-ready Play graphics and screenshots in store-assets/, and the generators for those assets in tools/.

# Turns raw device screenshots into Play-legal store screenshots.

|
# ./tools/make-store-screenshots.sh [raw-dir] [output-dir]
|
|
#
|
|
# Both paths default to inside the repo, never to $HOME:
|
|
# raw store-assets/raw-screenshots/ git-ignored staging for the `adb` captures
|
|
# output store-assets/screenshots/ the cropped files that get uploaded to Play
|
|
#
|
|
# Why this exists: Play rejects a screenshot whose longer side is more than twice its
|
|
# shorter side ("your screenshot's maximum dimension can't be more than twice its minimum
|
|
# dimension"). A 1080 x 2400 phone capture is 2.22:1, so it has to become 1080 x 2160.
|
|
#
|
|
# The crop removes system chrome only — the status bar at the top, the navigation bar at the
|
|
# bottom — never app content. Both heights were measured on the test device:
|
|
#
|
|
# STATUS_BAR_PX ITYPE_STATUS_BAR frame height 93 px (1080 x 2400 @ 440 dpi)
|
|
# NAV_BAR_PX ITYPE_NAVIGATION_BAR bottom inset 130 px (same device)
|
|
#
|
|
# adb shell dumpsys window displays | grep -oE 'ITYPE_STATUS_BAR frame=\[[^]]*\]\[[^]]*\]'
|
|
# adb shell dumpsys window displays | grep -oE 'control type=ITYPE_NAVIGATION_BAR.*mInsetsHint=\{[^}]*\}'
|
|
#
|
|
# Output is 24-bit PNG without alpha, which is what Play asks for. Captures are not shot by
|
|
# this script — take them yourself (the shot list is in docs/STORE_LISTING.md) and drop them
|
|
# into store-assets/raw-screenshots/, or pass the directory as the first argument.
