        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_alignParentBottom="true" />

3.Copy the following code and paste into "MainActivity.java"

package app.mitindia.com.mywebapp;
import android.app.Activity;
import android.os.Bundle;

import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

import java.io.FileInputStream;
import java.io.FileOutputStream;



public class MainActivity extends Activity  {
    Button b1;
    EditText ed1;

    private WebView wv1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        b1=(Button)findViewById(R.id.button);
        ed1=(EditText)findViewById(R.id.editText);

        wv1=(WebView)findViewById(R.id.webView);
        wv1.setWebViewClient(new MyBrowser());

        b1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String url = ed1.getText().toString();

                wv1.getSettings().setLoadsImagesAutomatically(true);
                wv1.getSettings().setJavaScriptEnabled(true);
                wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

                WebSettings webSettings = wv1.getSettings();
               // webSettings.setPluginsEnabled(true);
                webSettings.setJavaScriptEnabled(true);
                webSettings.setDatabaseEnabled(true);
                webSettings.setDomStorageEnabled(true);
                webSettings.setAppCacheEnabled(true);
                webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);

                wv1.loadUrl(url);
            }
        });
    }

    private class MyBrowser extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.

        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}
