Android Wear is a version of Google's Android operating system designed for smartwatches and other wearables.[8][9] By pairing with mobile phones running Android version 4.3+, Android Wear integrates Google Now[10] 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. Companies such as Motorola, Samsung, LG, HTC and Asus have been 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".[12]

Shape types of Android Wear–based watches include round, square and rectangular-shaped watch faces.

Launch devices include Motorola Moto 360,[13] LG G Watch,[14] Samsung Gear Live,[15] Asus ZenWatch,[16] Sony SmartWatch 3,[17] and LG G Watch R,[18] Hardware manufacturing partners include ASUS, Broadcom, Fossil, HTC, Intel, LG, MediaTek, Imagination Technologies, Motorola, Qualcomm, and Samsung.

Why Apache Software License? ... For userspace (that is, non-kernel) software, we do in fact prefer ASL2.0 (and similar licenses like BSD, MIT, etc.) over other licenses such as LGPL. Android is about freedom and choice. The purpose of Android is promote openness in the mobile world, but we don't believe it's possible to predict or dictate all the uses to which people will want to put our software. So, while we encourage everyone to make devices that are open and modifiable, we don't believe it is our place to force them to do so. Using LGPL libraries would often force them to do so.
