Google has extended the Android Honeycomb APIs so as to facilitate the third-party developers in making their applications work better on the bigger form factors and the most notable changes that the Android 3.0 SDK has unveiled include the new ActionBar for apps to display the title, the toolbar buttons and a standard menu button……..
Android 3.0 SDK preview offers an early look at some of the new features available to developers.One of the most visible changes in Honeycomb applications is the new ActionBar which replaces the titlebar at the top of the screen.ActionBar is responsible for displaying the title, the toolbar buttons for significant actions and a standard menu button that provides access to additional actions.Another major new feature in the Android 3.0 SDK is the fragment system which makes user interfaces more modular and simplifies the process of developing applications with multiple panes. Developers can use fragments to define user interface pieces that are combined in layouts within an Activity. Google has added generic drag-and-drop APIs. This feature isn’t fully documented yet, but there is an instructive example in Google’s API demo code. Google has also added richer clipboard APIs an extensible DRM framework, support for processors with multiple cores, and a new hardware-accelerated rendering framework that will improve the performance of Android‘s user interface drawing. All of these new capabilities bring value to the platform and will help developers build richer and more sophisticated applications.
