iOS, Android and cross-platform crashes, builds, store rejections.
A practical crash triage workflow for iOS and Android teams: get readable stack traces with dSYMs and R8 mapping files, group crashes sensibly, reproduce with context, fix with a test and confirm the fix per release with staged rollouts.
After upgrading to React Native 0.79 with the New Architecture on by default, our in-house printer module came back null on iOS and crashed on Android. Bridge-only registration and direct bridge calls were the cause; here is the migration path.
Bumping targetSdk to 35 put our toolbar under the status bar and the Pay button under the navigation bar on Android 15 devices. Edge-to-edge is now enforced, so we handled window insets properly in both Views and Compose screens.
A new Android Studio with JDK 21 forced a Gradle upgrade, the Gradle upgrade pulled in AGP 8, and AGP 8 rejected two old Flutter plugins with Namespace not specified. How we untangled the Gradle, AGP, Kotlin and JDK chain.
