The WebView class is an extension of Android's View class that allows you to display web pages as a part of your activity layout. It does not include any features of a fully developed web browser, such as navigation controls or an address bar. All that WebView does, by default, is show a web page. A common scenario in which using WebView is helpful is when you want to provide information in your app that you might need to update, such as an end-user agreement or a user guide.
Within your Android app, you can create an Activity that contains a WebViewthen use that to display your document that's hosted online.
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 email. In this case, you might find that it's easier to build a WebView in your Android app that shows a web page with all the user data, rather than performing a network request, then parsing the data and rendering it in an Android layout.

WebViews currently use their own cookie manager, which means that any network requests you make outside of these web views are usually stored separately.
This can cause problems when trying to retain the same cookies i. The simplest approach as proposed in this Stack Overflow article is to implement a cookie handler that forwards all requests to the WebView cookie store. See this gist for an example.
