Android WebView Example
Open Web URL
For opening a url we use loadURL() method of WebView class. By default the url is opened in android browser. As we have to open it inside the activity so we have to provide our own WebViewClient.
In this example the activity consists of three UI components namely EditText, Button and WebView. When user will enter url of a website in the edittext and click on button then the website will open in webview.

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