Demo of how to debug code inside a mobile webview

I thought that didn't work on the actual device, which frequently is different enough from the simulator that Catalyst could still be extremely useful.

Also, I've never looked into it, but is there any comparable built-in debugging method for Android?

That won't compile under ARC unless you declare +_enableRemoteInspector somewhere:

    objc_msgSend(NSClassFromString(@"UIWebView"), @selector(_enableRemoteInspector));

That's fine if you have yourself setup for native development. We're about helping web developers who don't want to do that.

Oh my bad, looks like there was a snafu exporting from Camtasia so the screen freezes halfway but the audio continues. Fixing now...

You hopefully get the gist from the audio in the meantime, or can read up in the blog post or at https://trigger.io/catalyst

Yup, same here. Still, the overall concept is interesting and potentially useful enough that I'm going to try it out.

You mean, for example, using Safari to debug mobile Safari / webview-based apps? That'll get you about 80% there, but environment differences (i.e., memory and processor limitations) on the device and quirky rendering behavior in mobile webkit almost always result in weird bugs that traditionally have required a lot of poking around blindly to fix. Differences between the simulator and the actual device are fairly common too.

It's only fairly recently that useful debugging tools like this and the built-in iOS 5 stuff have emerged.

Doesn't seem quite as easy as copying a script tag into your index.html and clicking a link...

Yes, there are various options including using Weinre locally.

By hosting Weinre we've tried to make it simpler than making sense of these instructions for example: http://www.webkit.org/blog/1875/announcing-remote-debugging-...

Similar, since it's based on the same open source project: Weinre.

We've added a tab to let you track calls out to the native bridge, see error / success codes and the response. Pretty useful when you're working on hybrid apps.
