In this tutorial how to build web apps using WebView Control in Android Application is shown.<\/p>\n
The WebView class is an extension of Android View class that allow you to display webpages as a part of your activity layout, it does not include any features of full developed web browser such as navigation bar, address bar etc.<\/p>\n
Another scenario in which WebView can help is if your app provides data to the user that always requires an internet connection to retrieve data such as image.<\/p>\n
To handle the navigation for webpage call goBack() method and goForward() method which will show you the history of webpages.<\/p>\n
The canGoBack() returns true if there is actually webpage history for the user to visit.<\/p>\n
Code:<\/p>\n
