Google Sets 64-Bit Mandate for Wear OS Apps by September 2026

Google sets a six-month runway for 64-bit builds with support for existing 32-bit watches unchanged.

Overview

Google will require Wear OS apps to include 64-bit versions starting September 15, 2026, with Google Play blocking uploads that do not comply.
The rule covers new apps and updates that include native code, which must ship a 64-bit build alongside any 32-bit build.
Google Play will continue delivering apps to current 32-bit Wear OS devices, so users on older watches will keep receiving apps and updates.
Google advises developers to check for native libraries added by SDKs, include arm64-v8a alongside armeabi-v7a, and test on the Wear OS Android Emulator.
Google says most Wear OS apps already meet the requirement and frames the shift as a performance and future-proofing move that follows Android’s 2019 mobile and recent Google TV 64-bit steps.
