How to view your web-page source code in android device

First create a project with the name WebsiteAnalysisTools and have a main activity with following code:

package com.clearpath.websiteanalysistools;

import java.io.IOException;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicResponseHandler;
import org.apache.http.impl.client.DefaultHttpClient;
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

   EditText url_text;
   TextView textView;  
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        url_text = (EditText) findViewById(R.id.address);
        textView = (TextView) findViewById(R.id.tv);
   }
    
    public void myButtonClickHandler(View view) {
        new GrabURL().execute();
    }
    
    private class GrabURL extends AsyncTask<String, Void, Void> {
        private final HttpClient Client = new DefaultHttpClient();
        private String response_str;
        private String Error = null;
        private ProgressDialog Dialog = new ProgressDialog(MainActivity.this);
        
        protected void onPreExecute() {
        Dialog.setMessage("Processing..");
            Dialog.show();
      }
  protected Void doInBackground(String... urls) {
            try {
             HttpGet request = new HttpGet(url_text.getText().toString());
                  // Get the response
                  ResponseHandler<String> responseHandler = new BasicResponseHandler();
                  response_str = Client.execute(request, responseHandler);
                  Log.d("HTML:", response_str);
            } catch (ClientProtocolException e) {
                Error = e.getMessage();
                cancel(true);
            } catch (IOException e) {
                Error = e.getMessage();
                cancel(true);
            }
            
            return null;
        }
        protected void onPostExecute(Void unused) {
            Dialog.dismiss();
           textView.setText(response_str);
            if (Error != null) {
                Toast.makeText(MainActivity.this, Error, Toast.LENGTH_LONG).show();
            } 
        }
        
    }

}

The main layout file is presented here which is activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="vertical" android:layout_width="fill_parent"

    android:layout_height="fill_parent">

    <EditText android:layout_height="wrap_content"

        android:layout_width="fill_parent"

        android:id="@+id/address"

        android:hint="http://www.google.com"

        android:singleLine="true">

    </EditText>

    <Button android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="Read Webpage"

        android:id="@+id/ReadWebPage"

        android:onClick="myButtonClickHandler">

    </Button>

    <ScrollView

        android:id="@+id/ScrollView01"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content">

        <TextView

            android:layout_width="fill_parent"

            android:layout_height="fill_parent"

            android:id="@+id/tv"

            android:scrollbars="vertical">

        </TextView>

    </ScrollView>

</LinearLayout>

The manifest should have following permissions:

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