How It Works
The Google Play services client library
The client library contains the interfaces to the individual Google services and allows you to obtain authorization from users to gain access to these services with their credentials. It also contains APIs that allow you to resolve any issues at runtime, such as a missing, disabled, or out-of-date Google Play services APK. The client library has a light footprint if you use ProGuard as part of your build process, so it won't have an adverse impact on your app's file size.
If you want to access added features or products, you can upgrade to a new version of the client library as they are released. However, upgrading is not necessary if you don't care about new features or bug fixes. We anticipate more Google services to be continuously added, so be on the lookout for these updates.
The Google Play services APK
The Google Play services APK contains the individual Google services and runs as a background service in the Android OS. You interact with the background service through the client library and the service carries out the actions on your behalf. An easy-to-use authorization flow is also provided to gain access to the each Google service, which provides consistency for both you and your users.
The Google Play services APK is delivered through the Google Play Store, so updates to the services are not dependent on carrier or OEM system image updates. In general, devices running Android 2.3 (Gingerbread) or later and have the Google Play Store app installed receive updates within a few days. This allows you to use the newest APIs in Google Play services and reach most of the devices in the Android ecosystem (devices older than Android 2.3 or devices without the Google Play Store app are not supported).
The benefits for your app
Google Play services gives you the freedom to use the newest APIs for popular Google services without worrying about device support. Updates to Google Play services are distributed automatically by the Google Play Store and new versions of the client library are delivered through the Android SDK Manager. This makes it easy for you to focus on what's important: your users' experience.
