Google Play to enforce 64-bit requirement for Wear OS apps starting September 2026

Developers building for Wear OS will soon be required to support 64-bit architectures, as Google expands its platform-wide transition to modern processing standards.

Beginning September 15, 2026, all new apps and updates containing native code must include both 32-bit and 64-bit versions to be accepted on Google Play. Apps that fail to meet the requirement will be blocked from submission via the Play Console. Existing support for 32-bit devices will remain unchanged, with apps still distributed to compatible hardware.

The update brings Wear OS in line with broader ecosystem changes, following similar 64-bit requirements introduced for mobile platforms in 2019 and extended to other device categories such as Google TV. The move is intended to standardize performance capabilities and ensure compatibility with newer hardware.

For many developers, the transition is expected to require minimal effort. Applications built entirely with managed code, such as Kotlin or Java, may not need modification. However, developers are advised to verify whether third-party libraries or SDKs introduce native components that require 64-bit support.

Google recommends auditing app packages using tools like the APK Analyzer in Android Studio to identify native libraries and confirm the presence of corresponding 64-bit binaries. Developers relying on outdated or 32-bit-only dependencies are encouraged to update or replace them ahead of the deadline.

Testing will also play a key role in the transition. Developers are expected to ensure feature parity and performance consistency between 32-bit and 64-bit versions, using the Wear OS emulator or compatible hardware environments. Particular attention is required for native loaders and legacy libraries that may not function correctly on 64-bit-only systems.
