PreRequirements :
- Eclipse IDE

here you can get http://developer.android.com/sdk/index.html
For Windows users may be this http://www.youtube.com/watch?v=TTrUX1kUpDo video will help or do other searches.
Steps
1. Creation of project..
In Eclipse, choose file -> new -> android app project.
give app name and choose next
choose icon click next and create a blank activity and choose finish..
2. Creation of html file as application..
Assume that this html file is your application.
just close that default opened xml file.
create a html file inside the folder assets
right click on assets and choose new -> file
and give file name ex) my_app.html
Note : open all the files using the text editor..
sample html file
----------- my_app.html--------
<html>
<head>
<script language="javascript">
function modify()
{
var obj=document.getElementById("h2");
obj.innerHTML="Using Html javascript any thing is possible !";
}
</script>
</head>
<h1 >This is Android Web Application</h1>
<h2 id="h2">Is it Possible ?</h2>
<body>
<input type="button" value="Click Me" onclick="modify()"></input>
</body>
</html>
----------------------------------------
3. Creation of Webview layout..
create an xml file "webview.xml" inside the folder
res -> layout ->webview.xml
right click on the layout folder and click new -> file ..
webview.xml should contains following .. just copy and paste the following
----------- webview.html--------
<?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"
/>
----------------------------------------
4. Modification in MainActivity.java file..
Open the MainActivity.java file in the folder
src -> com.package.yourappname -> MainActivity.java
delete the @Override public boolean onCreateOptionsMenu(Menu menu) {} method
import the android.webkit.WebView package..
type the following line on the top
" import android.webkit.WebView; "
create one object for the WebView class
type the following line after this public class MainActivity extends Activity {
" private WebView webView; "
inside the onCreate(Bundle savedInstanceState) method
set the content view to webview layout.
modify this "setContentView(R.layout.activity_main)" line to "setContentView(R.layout.webview)"
and add the following lines after the setContentView() method
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("file:///android_asset/my_app.html");
Note: html file name should be your file name ,in my case it was my_app.html
now your MainActivity is looking like the following
----------MainActivity.java----------------
package com.example.webapplication;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.webkit.WebView;
public class MainActivity extends Activity {
private WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("file:///android_asset/my_app.html");
}
}
-----------------------------------------------
5.Modification in the AndroidManfest.xml file..
open the AndroidManfest.xml file and add the following line between the <uses-sdk tag > and <application tag>
<uses-permission android:name="android.permission.INTERNET" />
6. Run the Project..
Save all the files and
Right Click on the project and choose run as -> Android Application project.
