Experimental APIs

In addition to the standard APIs, Crosswalk provides additional experimental or emerging standards APIs to further support building a native application experience using web platform technologies.

Device Capabilities - Retrieve information about the underlaying system.
Launch Screen - Display a static user interface on application launch and hide it when the application is ready.
