Google is extending its 64-bit requirement to Wear OS apps, effective September 15, 2026. New and updated apps submitted to Google Play must include 64-bit versions. Most Wear OS developers are already compliant, and apps written purely in Kotlin or Java require no code changes. However, developers should check dependencies and SDKs for native code that may need updates. The Wear OS Android Emulator can be used to verify 64-bit compatibility, and Google provides detailed documentation to assist with the transition.
