Halodoc's engineering team shares their experience migrating Android apps to API level 36 (Android 16). The post covers all major breaking changes: mandatory edge-to-edge rendering (no opt-out), predictive back navigation replacing onBackPressed(), adaptive layout enforcement on large screens (≥600dp), foreground service compliance, 16 KB page size support, stricter intent security, and auto-permission revocation. For each change, the team details their adoption approach, testing strategy, and pitfalls to avoid. The migration required upgrading the full build toolchain (AGP 8.11, Gradle 8.13, Kotlin 2.2, JDK 17) and was rolled out in phases from 1% to 100% of production users with continuous monitoring of crash rates and vitals.
