Smart app updates is a new feature of Google Play that introduces a better way of delivering app updates to devices. When developers publish an update, Google Play now delivers only the bits that have changed to devices, rather than the entire APK. This makes the updates much lighter-weight in most cases, so they are faster to download, save the device’s battery, and conserve bandwidth usage on users’ mobile data plan. On average, a smart app update is about 1/3 the size of a full APK update.
-Google Play services helps developers to integrate Google services such as authentication and Google+ into their apps delivered through Google Play.
-Google Play services will be automatically provisioned to end user devices by Google Play, so all you need is a thin client library in your apps.
+Google Play services is automatically provisioned to end user devices by Google Play, so all you need is a thin client library in your apps.
Because your app only contains the small client library, you can take advantage of these services without a big increase in download size and storage footprint. Also, Google Play will deliver regular updates to the services, without developers needing to publish app updates to take advantage of them.
