Developer Preview 2 is available for your smartwatch.

Google has released its second developer preview ofAndroid Wear 2.0, and it packs more than just some extra spit and polish. It now supports wrist gestures in third-party apps, to start. While you'll need apps to take advantage of this, it raises hope that your favorite fitness or messaging tool won't require a free hand (or your voice) for navigation.

What’s new? Platform API 24 - Google incremented the Android Platform API version number to 24 to match Nougat. You can now update your Android Wear 2.0 Preview project’s compileSdkVersion to API 24, and we recommend that you also update targetSdkVersion to API 24. Wearable Drawers Enhancements -Google launched the wearable drawers as part of the Android Wear 2.0 Preview 1, along with UX guidelines on how to best integrate the navigation drawer and action drawer in your Android Wear app. In Preview 2, we have added additional support for wearable drawer peeking, to make it easier for users to access these drawers as they scroll. Other UI improvements include automatic peek view and navigation drawer closure and showing the first action in WearableActionDrawer’s peek view. For developers that want to make custom wearable drawers, we’ve added peek_view and drawer_content attributes to WearableDrawerView. And finally, navigation drawer contents can now be updated by calling notifyDataSetChanged. Wrist Gestures: Since last year, users have been able to scroll through the notification stream via wrist gestures. Google have now opened this system to developers to use within their applications. This helps improve single hand usage, for when your users need their other hand to hold onto their shopping or their kids.
