Description

evalJS() doesn't work, period, on Android 2.2, but seems to on 1.6 and 3.0.

However, communicating back from the webview to the application doesn't work because there doesn't seem to be a similar mechanism in place as there is on iOS to inject the necessary Javascript at the head of the HTML, resulting in errors like:

E/Web Console( 504): ReferenceError: Can't find variable: Ti at file: ...

when trying to do something like Ti.App.fireEvent().

The following code demonstrates that Titanium now works as expected:

   var win = Ti.UI.createWindow({
   	backgroundColor : "blue",
   	exitOnClose:true
   });
   
   var view = Ti.UI.createWebView({
   	scalesPageToFit: false,
   	url:'myweb.htm'
   });
   view.addEventListener('load', function() {
   	Ti.API.info("************TITLE: " + view.evalJS("document.title"));
   	Ti.API.info("************CONTENT: " + view.evalJS('document.getElementsByTagName("html")[0].innerHTML'));
   });
   win.add(view);
   win.open();
