Just as earlier rumors this morning suggested, Google made the Android 4.4 KitKat SDK available shortly after launching the Nexus 5. Now developers can dive into the new OS from Google and see what hidden treasure are contained within. Here's just a few of them taken straight from the Android developer's blog:
  • New ways to create beautiful apps 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.
  • More useful than ever 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. You can integrate your app or storage service with the framework to give users instant access to their data.
  • 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. Apps can use adaptive playback to offer a significantly better streaming video experience.
  • RenderScript in the NDK 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.

If you are one of our amazing developers, please sound off in this thread and tell us which of these new development features intrigues you the most.
