Building Web Apps in WebView

If you want to deliver a web application (or just a web page) as a part of a client application, you can do it using WebView. 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.

Create your layout: activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<WebView 
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/webView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />

within your Activity: MainActivity.java

import android.os.Bundle;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends Activity {
    WebView webView;

    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       
        webView = (WebView)findViewById(R.id.webView1);
        webView.getSettings().setJavaScriptEnabled(true);
// Handling page navigation
        webView.setWebViewClient(new WebViewClient());
        webView.loadUrl("http://ashfaquedl.blogspot.in/");
        webView.getSettings().setSupportZoom(true);
        webView.getSettings().setBuiltInZoomControls(true);
    }
//  Navigating web page history
    @Override
    public void onBackPressed() {
        if (webView.copyBackForwardList().getCurrentIndex() > 0) {
            webView.goBack();
        }
        else {
            // Your exit alert code, or alternatively line below to finish
            super.onBackPressed(); // finishes activity
        }
    }

}
 Note: And most important thing don't forget to add below uses-permission in AndroidMenifest.xml.
<uses-permission android:name="android.permission.INTERNET"/>
now your app is rocking.
