The advice rotation charges again my webviews class

Question

When I rotate my devices, this charge again his class. For example, if I have a google search when I change the orientation charges again to google.

I've try it with:

@Override
public void onConfigurationChanged(Configuration newConfig) {
  super.onConfigurationChanged(newConfig);
  setContentView(R.layout.principal);
}

and onRestoreInstanceState and onSaveInstanceState. But my problem persist. I would appreciate if somebody can help me with a example or explication of how can to do it.

Thank's!

I've solved the problem, I needed to do the if (savedInstanceState == null) :

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.principal);

    webview.setWebViewClient(new WebViewClient());

    if (savedInstanceState == null)
    {
        webview.loadUrl("http://www.apple.es");
    }
}

  @Override   
    protected void onSaveInstanceState(Bundle outState)
    {  
      super.onSaveInstanceState(outState);  
      // Save the state of the WebView    
      webview.saveState(outState);
    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState)  
    {  
      super.onRestoreInstanceState(savedInstanceState);
      // Restore the state of the WebView
      webview.restoreState(savedInstanceState);
    }

I hope than my problem and my solution can help to somebody!

In these cases I just set the orientation and disable the auto rotation ...Do you really need auto rotation ? — moujib, May 17 '12 at 08:34

Add configChanges in your AndroidManifest file. For example:

<activity android:name="YourActivityName"
          android:configChanges="orientation">
</activity>

and save your current url in local variable and load it in onConfigChanges

@Override
public void onConfigurationChanged(Configuration newConfig) {
    yourWebView.loadUrl(yourUrl);
}

Christian you have to see this doc on android developer web site and learn how romain guy stores his last loaded image and call them when the configuration screen changes!! the solution is to use

onRetainNonConfigurationInstance()
getLastNonConfigurationInstance()

I also refer to this tutorial always to get rid of the screen change behavour of android
