64-bit architectures provide performance improvements and a foundation for future innovation, delivering faster and richer experiences for your users. We’ve supported 64-bit CPUs since Android 5. This aligns Wear OS with recent updates for Google TV and other form factors, building on the 64-bit requirement first introduced for mobile in 2019.
Today, we are extending this 64-bit requirement to Wear OS. This blog provides guidance to help you prepare your apps to meet these new requirements.
The 64-bit requirement: timeline for Wear OS developers
Starting September 15, 2026:
- All new apps and app updates that include native code will be required to provide 64-bit versions in addition to 32-bit versions when publishing to Google Play.
- Google Play will start blocking the upload of non-compliant apps to the Play Console.
We are not making changes to our policy on 32-bit support, and Google Play will continue to deliver apps to existing 32-bit devices.
The vast majority of Wear OS developers has already made this shift, with 64-bit compliant apps already available. For the remaining apps, we expect the effort to be small.
Preparing for the 64-bit requirement
Many apps are written entirely in non-native code (i.e. Kotlin or Java) and do not need any code changes. However, it is important to note that even if you do not write native code yourself, a dependency or SDK could be introducing it into your app, so you still need to check whether your app includes native code.
Assess your app
- Inspect your APK or app bundle for native code using the APK Analyzer in Android Studio.
- Look for .so files within the lib folder. For ARM devices, 32-bit libraries are located in lib/armeabi-v7a, while the 64-bit equivalent is lib/arm64-v8a.
- Ensure parity: The goal is to ensure that your app runs correctly in a 64-bit-only environment. While specific configurations may vary, for most apps this means that for each native 32-bit architecture you support, you should include the corresponding 64-bit architecture by providing the relevant
