Q:

Android - Preventing WebView reload on Rotate

When I rotate my screen, the WebView reloads the whole page. I can't have this since some of my content contains dynamic/random material. Currently when rotated the screen reloads the original URL from the loadUrl() method. 
Any idea what's wrong with my code? 
MainActivity.java
package com.mark.myapp;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.KeyEvent;
import android.view.Menu;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends Activity {

    WebView web;
    String webURL = "http://www.google.co.uk/";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if (savedInstanceState != null)
            ((WebView)findViewById(R.id.web)).restoreState(savedInstanceState);

        web = (WebView) findViewById(R.id.web);
        web.getSettings().setJavaScriptEnabled(true);
        web.loadUrl(webURL);
        web.setPadding(0, 0, 0, 0);
        web.getSettings().setLoadWithOverviewMode(true);
        web.getSettings().setUseWideViewPort(true);
        web.getSettings().setSupportZoom(true);
        web.getSettings().setBuiltInZoomControls(true);

        web.setWebViewClient(new HelloWebViewClient());
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    private class HelloWebViewClient extends WebViewClient {
        public boolean shouldOverrideUrlLoading(WebView web, String url) {
            web.loadUrl(url);
            return true;
        }
    }

    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && web.canGoBack()) {
            web.goBack();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }

}

AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mark.myapp"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"

            android:configChanges="orientation|keyboardHidden">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-permission android:name="android.permission.INTERNET"/>
</manifest>

A:

I think the main problem is that you call web.loadUrl(webURL); also when savedInstanceState != null
EDIT
Try:
if (savedInstanceState == null)
{
  web.loadUrl(webURL);
}

EDIT2: You also need the onSaveInstanceState and onRestoreInstanceState override.
@Override
protected void onSaveInstanceState(Bundle outState )
{
super.onSaveInstanceState(outState);
web.saveState(outState);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState)
{
super.onRestoreInstanceState(savedInstanceState);
web.restoreState(savedInstanceState);
}

Note: Please also add in your AndroidManifest.xml in your Activity
    android:configChanges="orientation|screenSize"
Thanks

No java coding needed.
use this in your manifest file.
 android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"

like:
<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.Example.WebviewSample.webviewsample"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>        
</application>

A:

in  tag (manifest)
android:configChanges="orientation|screenSize"
