Google Play flagged three things against 1.5.12, and all three have been worked through. The deprecated edge-to-edge APIs — setStatusBarColor, getStatusBarColor and setNavigationBarColor — were being called from two different libraries, React Native's own StatusBarModule and WindowUtilKt, and react-native-edge-to-edge. Play scans for the static bytecode reference, so wrapping the calls in a version check never cleared the warning; every call site now reaches them through reflection instead, which keeps the behaviour identical on Android 14 and below and removes the reference entirely. React Native ships as a prebuilt binary, so that half required re-publishing a patched react-android artifact and verifying with javap that no reference survived and that every method the original exposed is still present.

On R8, the real cause turned out not to be the setting first suspected: code shrinking was already enabled, but the build was pulling in the non-optimized default ProGuard file, which carries -dontoptimize and switches R8's optimization passes off wholesale. That file is now the optimized variant, and optimized resource shrinking is enabled alongside it. The remaining sub-item — Android Gradle Plugin 9.0 — is set by the Expo SDK and cannot be changed independently. The bitmap recommendation led to a genuine bug: picked and captured photos were being handed to the preview at full resolution, so a 12-megapixel photo became a ~48 MB bitmap and a 50-megapixel one roughly 200 MB. Images are now capped before they are decoded, which costs nothing in output quality because the saved image is a capture of the on-screen view. The app targets API 36. Play re-evaluates against an analysed release, so these results are confirmed by the store only once 1.5.13 has been through review.
