Android 4.3, updated developer tools, and backwards compatible Action Bar Available Now 

Android 4.3, a sweeter version of Jelly Bean, includes performance enhancements to keep your apps fast, smooth, and efficient; together with new APIs and capabilities including:

* OpenGL ES 3.0 Take advantage of OpenGL ES 3.0 and EGL extensions as standard features of Android, with access from either framework or native APIs.

* Bluetooth Smart Communicate with low-power Bluetooth Smart devices and sensors to provide new features for fitness, medical, location, proximity, and more.

* Restricted profiles Tablet owners can create restricted profiles to limit access to apps, for family, friends, kiosks, and more. Your app can offer various types of restrictions to let tablet owners control its capabilities in each profile.

* New media capabilities A modular DRM framework enables you to more easily integrate DRM into your streaming protocols, and apps can also access a built-in VP8 encoder from framework or native APIs for high-quality video capture.

* Notification access: Access and interact with  the stream of status bar notifications as they are posted — including routing them to nearby Bluetooth devices!

* Improved profiling tools New tags in Systrace, and on-screen GPU profiling, give you new ways to optimize performance.

We’re also releasing a new version of the Android NDK (r9), which provides native access to the OpenGL ES 3.0 APIs and other stable APIs in Android 4.3. 

The Support Package has also been updated with the long awaited Action Bar API that lets you include this Android design pattern in your app with compatibility back to Android 2.1. 

You can download the Android 4.3 Platform (API level 18), as well as the SDK Tools, Platform Tools, and Support Package from the Android SDK Manager.

Android 4.3 powers the new Nexus 7 tablet and is rolling out now as an update to Nexus 4, Nexus 7, Nexus 10, and Galaxy Nexus HSPA+ devices.
