Description
This sniplets are working under all versions of simulator, but
when I install the application on Android 2.2 (Nexus One), events
are not working.
So I can't pass data between windows and webviews.
win.js
var win = Ti.UI.currentWindow;
var webCurView = Ti.UI.createWebView({url:'web2.html'});
webCurView.addEventListener('load', function() {
Titanium.App.fireEvent('pageReady',{latx:39.92, lngx:32.80, laty:39.86, lngy: 32.85});
});
win.add(webCurView);
The problem I have is that the Titanium object (and thus Titanium.App.addEventListener) is undefined in the web view's JavaScript when launched on a Nexus One running the official Android 2.2 release. As with Alper's report, everything works fine in the emulator (2.2-APIs).
I was able to work around this for my case by re-including the system's binding.js in my HTML file; I think there's some order of operations problem where it's getting evaluated when the WebView is set up, but before the TiApp and TiAPI objects are fully available yet:
E/Web Console( 2106): Uncaught ReferenceError: TiAPI is not defined at :3
I've simply copied binding.js from here:
http://github.com/appcelerator/titanium_mobile/blob/master/android/modules/ui/src/ti/modules/titanium/ui/widget/webview/binding.js"> http://github.com/appcelerator/titanium_mobile/blob/master/android/...
and dropped it into my HTML before my own scripts:
<!-- hack for initialization bug on Android --> Since it checks for the short-form 'Ti' already being set up in the global namespace, it's a no-op when everything's already been set up for us so it doesn't interfere with iPhone, or with a correctly established namespace.That'll be a <script src="binding.js"></script> of course... formatting ate the tag in post above. :)
