Google Analytics and Google Tag Manager
Developers will now be able to get detailed statistics on how your app is bing used by your users. These details will let you know the most used functionality of your app.
With the Tag Manager, you can now change the characteristics of your app on-the-fly without requiring for an update to be pushed from Google Play.
Google Play Games services Update
Game Gifts will allow players to send virtual in-game requests to anyone in their Google Plus circles or through player search. The user can also request a benefit or item.
The 4.3 release adds three important features to the Drive API :
1. Pinning – Pinning will let you pin files that should be kept up to date locally, ensuring that it is available when the user is offline. It is useful for users with limited or no connectivity.
2. App Folders – An app often needs to create files which are not visible to the user, for example to store temporary files in a photo editor. This can now be done using App Folders, a feature is analogous to Application Data Folders in the Google Drive API
3. Change Notifications – You can now register a callback to receive notifications when a file or folder is changed. This mean you no longer need to query Drive continuously to check if the data has changed, just put a change notification on it
In addition to the above, you also get ability to access a number of new metadata fields.
With Address API, you can request access to addresses to fill out a delivery address form. For the convenience of the user, kicker has been introduced. The user needs to only select the address and the entire form will be filled.
The SDK for the new APIs will be available for download after the global rollout is complete.
