Android WebView Orientation Changes

We know, Android destroys the current activity and re-creates the same activity all over again.So for the webview it has to reload the page during orientation changes.

This can be resolved by overriding onSaveInstanceState(Bundle outState) in your activity and calling saveState from the Webview:

@Override


protected void onSaveInstanceState(Bundle outState) {


webView.saveState(outState);


}


Then rewrite your onCreate :

public void onCreate(final Bundle savedInstanceState) {


super.onCreate(savedInstanceState);


setContentView(R.layout.blah);


if (savedInstanceState != null)


((WebView)findViewById(R.id.webview)).restoreState(savedInstanceState);


else
webview.loadUrl("yourUrl");


}


And set the android:configChanges attribute in the manifest:

android:label="@string/appName"
android:configChanges="keyboardHidden|orientation"
