Google fleshes out Android 4.4 details
Dave Burke, Engineering Director for the Android Platform, writes on the Android Developers Blog:
As part of this release, we kicked off Project Svelte, an effort to reduce the memory needs of Android so that it can run on a much broader range of devices, including entry-level devices that have as little as 512MB RAM. From the kernel to system, frameworks, and apps, we’ve reduced memory footprint and improved memory management so Android can run comfortably on only 512MB of RAM. We did this not only on Android but across Google apps, like Chrome and YouTube.
By supporting a broader range of devices, Android 4.4 will help move the Android ecosystem forward. Now all users will be able to enjoy the very best that Android has to offer, on the devices that best meet their needs.
Highlighted new features for developers are:
- App immersion — A new full-screen immersive mode lets your app or game use every pixel on the screen to showcase content and capture touch events. A new transitions framework makes it easier to animate the states in your UI. Web content can take advantage of a completely new implementation of WebView built on Chromium.
- Printing — “A printing framework lets you add the convenience of printing to your apps. A storage access framework makes it easier for users find documents, photos, and other data across their local and cloud-based storage services.”
- Low-power sensors — “New hardware-integrated sensors let you add great new features to your apps without draining the battery. Included are a step detector and step counter that let you efficiently track of the number of walking steps, even when the screen is off.”
- New media capabilities — “A new screen recorder lets you capture high-quality video of your app directly from your Android device. It’s a great new way to create walkthroughs, tutorials, marketing videos, and more.”
- RenderScript (an API for intensive computation) — “A new C++ API in the Android Native Development Kit (NDK) lets you use RenderScript from your native code, with access to script intrinsics, custom kernels, and more.”
- Improved accessibility support — “New system-wide captioning settings let your apps present closed captions in the style that’s preferred by the user.”
