Wear OS is now requiring all new apps and updates with native code to include 64-bit versions alongside their 32-bit counterparts starting September 15, 2026. This change aligns Wear OS with other Google platforms and enhances user experiences through improved performance and future innovation. Google Play will block non-compliant apps from being uploaded after this date. The policy will continue to support existing 32-bit devices, and most developers have already transitioned to 64-bit. Apps written purely in Kotlin or Java generally do not require code changes, but it's crucial to check for any underlying native code dependencies. Developers can inspect their APK or app bundle for native libraries using Android Studio's APK Analyzer. The primary goal is to ensure parity, meaning for every supported 32-bit native architecture, a corresponding 64-bit architecture must be provided. If third-party SDKs only offer 32-bit versions, developers should request 64-bit compliant updates from their providers. Testing 64-bit compatibility can be done using the Wear OS Android Emulator to confirm the app functions and performs equivalently to its 32-bit version. Developers are encouraged to refer to detailed documentation for further guidance on this transition.
