Google has today announced that the final SDK for Android Wear 2.0 is now available, bringing support for new LG Watch Style and Sport hardware announced yesterday (and their special features, like that rotating crown, officially named the “rotating side button”)…

Everyone can use an Echo Dot: Just $50!

Specifically, this SDK adds support for physical button locations and rotary input, which will require developers to actually own an LG Watch Style or Sport to test these features. Rest assured, however, that Google is working on adding these features to the Android emulator soon.

Google is also changing the app review process for Android Wear:

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.

You can learn more about the new SDK over at the Android Developers website.
