Android orientation Change in WebView

I am Using Following Code to stop reloading the web page 

public class MainActivity extends Activity {


WebView webView;

@Override


protected void onSaveInstanceState(Bundle outState) {


    WebView webView1 = (WebView)findViewById(R.id.webView);
     webView1.saveState(outState);


}    

@SuppressLint("SetJavaScriptEnabled")
@Override
public void onCreate(Bundle savedInstanceState) {


    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    webView = (WebView)findViewById(R.id.webView);

    String url="http://www.google.com";


             if (savedInstanceState != null)
                        {
                 ((WebView)findViewById(R.id.webView)).restoreState(savedInstanceState);
                        }
             else{

             webView.setWebViewClient(new WebViewClient() {


        public void onPageFinished(WebView view, String url) {

            String name = MainActivity.this.webView.getTitle();
            TextView t=(TextView)findViewById(R.id.title); 

            t.setText(name);
            Toast.makeText(getApplicationContext(), name, Toast.LENGTH_SHORT).show();


        }
    });



    final Activity activity = this;

    final ProgressDialog progressDialog = new ProgressDialog(activity);
    progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
    progressDialog.setMessage("Loading...");
    progressDialog.setCancelable(false);

    final ProgressBar progressBar = (ProgressBar)findViewById(R.id.progressBar1);


    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setDomStorageEnabled(true);
    webView.getSettings().setUserAgentString("Android");
    webView.setWebChromeClient(new WebChromeClient()
    {
         public void onProgressChanged(WebView view, int progress) {

                progressBar.setVisibility(View.VISIBLE);
                progressDialog.setProgress(0);
                activity.setProgress(progress * 1000);

                progressDialog.incrementProgressBy(progress);

                if(progress > 75)
                    progressBar.setVisibility(View.GONE);
            }
    }
            );


    webView.loadUrl(url);

             }

Try this

in activity tag, manifest

android:screenOrientation="sensor"
        android:configChanges="keyboardHidden|orientation|screenSize"

java

@Override
 public void onConfigurationChanged(Configuration newConfig) {
 super.onConfigurationChanged(newConfig);
 // We do nothing here. We're only handling this to keep orientation
 // or keyboard hiding from causing the WebView activity to restart.
}

In my code where WebView is in fragment:

In manifest:

<activity 
...
android:configChanges="orientation|keyboard|screenSize"
... />

In activity:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
}

In fragment:

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    webView.saveState(outState);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    if (savedInstanceState == null)
        webView.loadUrl("about:blank");
    else
        webView.restoreState(savedInstanceState);
}

and when orientation change it's change smoothly.

You need to use configChanges attribute for for Activity in manifest file. So use below code in your Manifest file for each activity.

<activity android:name=".YOUR_ACTIVITY_NAME" android:configChanges="orientation|keyboard|keyboardHidden"/>

When you are not using configChanges then onCreate() method again called when device orientation change or some other configuration changes.

By default the activity is recreated at orientation change. But you can change it by setting android:configChanges="keyboardHidden|orientation in the declaration of your activity in AndroidManifest.xml and overriding the onConfigurationChanged() method of the activity class.
