Analysis on Webview for Android

Desc on Webview

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.

Note that, in order for your Activity to access the Internet and load web pages in a WebView, you must add the INTERNET permissions to your Android Manifest file:

1
<uses-permission android:name="android.permission.INTERNET" />

This must be a child of the element.

Using of Webview

By default, a WebView provides no browser-like widgets, does not enable JavaScript and web page errors are ignored. If your goal is only to display some HTML as a part of your UI, this is probably fine; the user won’t need to interact with the web page beyond reading it, and the web page won’t need to interact with the user. If you actually want a full-blown web browser, then you probably want to invoke the Browser application with a URL Intent rather than show it with a WebView. For example:

1
2
3
Uri uri = Uri.parse("http://www.example.com");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

See Intent for more information.

To provide a WebView in your own Activity, include a in your layout, or set the entire Activity window as a WebView during onCreate():

 WebView webview = new WebView(this);
 setContentView(webview);
``` 
Then load the desired web page:
```java
 // Simplest usage: note that an exception will NOT be thrown
 // if there is an error loading this page (see below).
 webview.loadUrl("http://slashdot.org/");

 // OR, you can also load from an HTML string:
 String summary = "<html><body>You scored <b>192</b> points.</body></html>";
 webview.loadData(summary, "text/html", null);
 // ... although note that there are restrictions on what this HTML can do.
 // See the JavaDocs for loadData() and loadDataWithBaseURL() for more info.
