A View that displays web pages. This class is the basis upon which you can roll your own web browser or simply display some online content within your Activity. It uses the WebKit rendering engine to display web pages and includes methods to navigate forward and backward through a history, zoom in and out, perform text searches and more.

Apart loading from the web, this component supports loading from assets (location file:///android_asset/, this folder must be called "assets" and be present in the project root) or other arbitrary folder. It also supports JavaScript but it is disabled by default and must be explicitly turned on.
