Today, we are releasing the final SDK for Android Wear 2.0. In this release, we have added support for the new hardware features announced yesterday . If you have not done so already, it really is time to publish your apps so as to not miss the consumer hardware launch tomorrow.

Standalone Android Wear apps and iOS support - Apps can now be downloaded directly to Wear devices via an on-watch Google Play Store. In addition, these apps can access the internet directly without relying on phone apps. This means that apps can now run on Android Wear devices that are paired to iOS devices.

New hardware support The first two watches with Android Wear 2.0 give users more ways to interact with their smartwatches. In the final SDK, we have added API support for physical button locations and rotary input . At present, developers will need the new LG Watch Style or LG Watch Sport to test these new functionalities; however, we are working to add these new hardware features to the emulator. Stay tuned for updates! The SDK also includes a few other final bug fixes, such as support for more than three items in the Wearable Action Drawer.

App review changes Now that Android Wear 2.0 is live, we'll soon update the Android Wear App Quality review process with two important changes. First, enhancing your phone app notifications for Android Wear will no longer be sufficient for passing the review. Second, it will soon be required that you upload a watch APK that's compatible with Android Wear 2.0. Only apps that pass these criteria will receive badging in Play Store on the phone and be eligible for top charts for Android Wear apps. These changes will ensure a more consistent experience for users and allow us to streamline the review process for you.

The journey doesn't stop here!
