Android 4.4 KitKat and the Nexus 5 are not the only thing that Google has unveiled today. The company will soon start rolling out the v4.0 of Google Play services to all Android 2.3+ devices.
The latest version of Play services includes a new Google Mobile Ads SDK, which should help in easier and seamless improvements to end users. For example, bug fixes and any enhancements can be automatically pushed without the developer doing anything.
Back at Google I/O, Google introduced a new location and geofencing API which was battery friendly and accurate as well. With the latest update, the API now has a lesser impact on battery life of the device.
Developers can code their applications to save the battery of the device by requesting a larger latency for the notification for existing or entering geofences. The accompanying Maps API has also been updated to add support for marker opacity, fade-in effects and visibility of 3D buildings.
Lastly, the Google+ Sign-In and Wallet Instant Buy are now updated with a simplified sign-in dialog. The updated APIs for Wallet “streamlines the buy-flow and reduces integration time.”
