After the official release on Wednesday, today Google allowed developers to snag the final version of the Android Wear 2.0 SDK, and prepare their older apps for the release of the next smart watches that will use the Android Wear 2.0 OS. LG’s newest smartwatches: Watch Sport and Watch Style are the first two devices running on version 2.0, and both will be available on Friday, February 10.
The new SDK for developers includes something news to add support in upcoming apps for the hardware additions and software improvements in Android Wear 2.0 OS. They include Material Design based system user interfaces and design guidelines that can be downloaded and installed without needing a smartphone, just support for releasing Android Wear apps and iOS support for apps. Also, the SDK lets developers create new types of faces for Android Wear 2.0 that can bring more features, not only displaying the time.
As we said earlier, the first two smartwatches run Android Wear 2.0 that will be sold on Friday are the LG Watch Sport and LG Watch Style. App developers will now have to get one of these smartwatches to make tests on the use of the new API support for physical button locations and rotary input. But with the update of the SDK at some point, these features can be tested with an emulator app.
In addition to updating the SDK, the app quality review process will require two new rules for Android Wear 2.0 apps. First, if apps just offer slight improvements from previous notifications made for a phone app, they won’t be accepted in the new review rules. Another is that developers will need to upload the Watch APK file compatible with Android Wear 2.0.
Although two new LG watches are the first devices running Android Wear 2.0, many older Android Wear devices will be updated to the 2.0 version just in the coming weeks and months.
