This can be handled by overrwriting onSaveInstanceState(Bundle outState) in your activity and calling saveState from the webview:

@Override protected void onSaveInstanceState(Bundle outState) {     webView.saveState(outState);     super.onSaveInstanceState(outState);  } 

Then recover this in your onCreate after the webview has been re-inflated of course:

@Override public void onCreate(final Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.blah);    WebView webview = (WebView)findViewById(R.id.webview);    if (savedInstanceState != null)       webview.restoreState(savedInstanceState);    else       webview.loadUrl(URLData) }
