The second developer preview for Android Wear 2.0 was showcased at the I/O event in 2016 and it features many improvements based on user suggestions for the previous Android Wear 1.x. By that we refer to the fact that it has been redesigned and that it now features notifications that are easier to see and read, smart replies, handwriting, a new user interface and support for keyboards.
Most of the overall changes are primarily related to how the messaging services work because most people use their smartwatches just for that.
Since the I/O event, Google has updated the Android API platform for the wearable device and it now runs on Android 7.0 Nougat. Along with this update the devs will have access to new wrist gestures and one handed use that can be unlocked for third party applications. Not only that, but Google has also included many design features that will make it easier for developers to design apps for wearables.
So far, the Android Wear 2.0 second developer preview is only available on the LG Watch Urbane Second Edition LTE and the Huawei Watch. If you don’t own these wearables you will have to wait a while longer until the preview is released for other devices. It’s very likely that that will happen very soon after Google oficially releases Android Nougat.
However, Google is strongly encouraging developers to check out the Android Wear 2.0 second developer preview and start making apps for the platform.
Here is some quick info on the evolution of the upcoming Android Wear 2.0: it’s based on suggestions from users regarding the improvement of the Android Wear 1.x. The latter was initially based on Android KitKat, but was updated afterwards in accordance with the Android Lollipop and finally, it was updated to match Android Marshmallow, the latest OS released by Google.
