Google Play Services 7.0 released, brings improvements to locations, Google Fit, and AdMob

Google has officially updated Play Services to version 7.0 bringing several new features and enhancements for developers to take advantage of. They had previously mentioned some additions to AdMob and Google Play Games, but now the entire service has been updated.

The new Places API seems like the biggest new addition to Play Services, as it will allow apps to get information from Google’s database of locations, venues, and restaurants, and users can quickly get info about the business in particular including addresses and phone numbers. 
Google Fit has introduced a handful of new APIs for tracking new measurements and sensors, and it’s supposedly significantly lighter on memory requirements for Fit apps. AdMobs is seeing some Google Analytics integrations, and Google Play Games has adopted a new feature that will let games use a nearby device as a second screen for content. This is especially useful for using your Android device as a controller on Android TV.
Although the developer SDK hasn’t gone live yet, this update should be hitting your devices in the near future. For Google’s full blog post about it, hit the link below.
