Android Wear

Android Wear Introduction

                         Android Wear is a version of Google’s Android operating system designed for smartwatches and other wearables. By pairing with mobile phones running Android version 4.3+, Android Wear integrates Google Now technology and mobile notifications into a smartwatch form factor. It also adds the ability to download apps from the Google Play Store.

The platform was announced on March 18, 2014, along with the release of a developer preview. At the same time, companies such as Motorola, Samsung, LG, HTC and Asus were announced as partners.[11] On June 25, 2014, at Google I/O, the Samsung Gear Live and LG G Watch were launched, along with further details about Android Wear. Motorola’s Moto 360 was released on September 5, 2014. On December 10, 2014, an update started to roll out that, among other new features, added a watch face API and changed the software to be based on Android 5.0 “Lollipop”.

Shape types of various launched devices include round, square and rectangular watch faces. Launch devices include the Motorola Moto 360, the LG G Watch, and the Samsung Gear Live so far.

Creating and Running a Wearable App

                      Wearable apps run directly on the wearable device, giving you access to low-level hardware such as sensors, activities, services, and more, right on the wearable.

This lesson goes over how to set up a device or emulator and create one project to contain both your wearable and handheld apps.
Update Your SDK

Before you begin building wearable apps, you must:

1. Update your SDK tools to version 23.0.0 or higher
The updated SDK tools enable you to build and test wearable apps.
2. Update your SDK with Android 4.4W.2 (API 20) or higher
The updated platform version provides new APIs for wearable apps.

To update your SDK with these components, see Get the latest SDK tools.
