Assume you have the following code snippet in your 
activity_main.xml
file:
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
android:id="@+id/WebView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

WebView
element defines a web browser in your Android activity. You can use it to load content 
from the web or resources stored locally in your application. 
The following code snippet shows how to load the 
WebView

package net.learn2develop.webbrowser;

import android.webkit.WebViewClient;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
