    onSaveInstanceState takes only one Bundle.

    Save the webview states into separate Bundles, then put them into the saved one:

    Bundle state1=new Bundle();
webview.saveState(state1);
Bundle state2=new Bundle();
webviewtwo.saveState(state2);
outState.putBundle("state1",state1);
outState.putBundle("state2",state2);
super.onSaveInstanceState(outState);

    Restoring:

    webview.restoreState(savedInstanceState.getBundle("state1"));
webviewtwo.restoreState(savedInstanceState.getBundle("state2"));
