Google has updated Google Play Services to version 7.3 that brings support for multiple Android Wear devices and other improvements. The update also adds changes that are developer specific.
Google is giving us the ability to connect and sync multiple wear devices to a single mobile device. This will help users to switch between smart watches easily.There is also an improvement to the Google API Client class to handle situations when APIs are not available on a given device. Updates have been made to location services also, expanding the maximum wait time for location updates.
Another new addition for Android Wear is the ChannelApi, which provides a bidirectional data connection between two nodes. While assets are the best way to efficiently add binary data to the data layer for synchronization to all devices, this API focuses on sending larger binary data directly between specific nodes. This comes in two forms: sending full files via the sendFile() method (perfect for later offline access) or opening an OutputStream to stream real time binary data. We hope this offers a flexible, low level API to complement the DataApi and MessageApi.

Moving to Google Fit, the update brings addition of nutrition data to Google Fit, as well as “improvements to retrieving the user’s activity and location, and better support for optional APIs, there’s a lot to explore in this release.” Developers can download the SDK right away by accepting the latest update.
