It looks like Google Play Services has just gotten a new update to pave the way for some of the new improvements for the Play Games app, as well as some new APIs, some revamped APIs for the ones that were already in place, and as always some bug fixes or fine tuning to smooth things out. This update, which is Google Play Services version 4.3 is in the process of rolling out at the time of publication, and comes after Google had announced that they would putting out an update for the services just this morning.
You probably already know about the Google Play Games features that are coming in the latest update for that particular app. Cross platform interaction, and also a new feature called game gifts were added to the app, and this new update to Google Play Services gets it in line with those new features. For developers, the update to Play Services brings new APIs, which include Drive APIs, Google Analytics APIs, Tag Manager APIs, and Address APIs. Google's idea was to take all of these new APIs and make them as easy to work with as possible for developers, and adding them into Play Services is the best way to do that. With the version release of this Drive API, developers will now be able to access handy new features like pinning files and changing notifications.
With the Tag Manager and Analytics APIs, developers will now be able to more easily track usage stats for their apps like what app features are being used most frequently, and changing small things about your app in a moment's notice without the need to send out an update to Google Play, for example, changing the color of an element within the app. Lastly within this new update, the Address API is brand new, and now allows developers to get an address for any reason they might need it without having to ask for the specific location of a users device. Think about how you might fill out a form for the delivery of a package. The new address API will now allow the user to select a certain address by way of a user interface component, which auto fills the entire form for them so developers no longer have to rely on location data and the actual location of a user to proceed. The update is being rolled out gradually.
