The Android Wearable Computing Revolution Begins

Hello readers!! With this blog I would like to share with a wonderful technology that on the rise in recent time. This is Android Wear. After smartphones, smart watches are the next in thing. So what exactly in Android Wear, its functionalities and how can we design one, ourselves.

Come let’s explore.

Android Wear is a version of Google’s Android operating system which has been designed for smart watches and other wearable devices. Android Wear supports both Bluetooth and Wi-Fi connectivity.

In 2014 Google officially announced Android wear, a new version of Android operating system.

Android Wear runs on a variety of devices, like first-generation of Motorola, LG’s G watch and Samsung Gear among others. Android supports 4.3 (API18) or higher that adds additional Android Wear specific UI controls.
