Seems like you would also need to update experimental.app.json to include the
launch data parameter (and define the type, for validation).

Additionally, if you include the type in the JSON file, the JSON schema compiler
will generate a struct for you that has a ToValue() method, so that you don't
need to hardcode the key names.

For an example, see the alarms API: 

The Alarm type is defined here:
http://code.google.com/searchframe#OAMlx_jo-ck/src/chrome/common/extensions/a...

The  generated code looks like:
http://code.google.com/searchframe#OAMlx_jo-ck/src/out/Release/obj/gen/chrome...

And is used here:
http://code.google.com/searchframe#OAMlx_jo-ck/src/chrome/browser/extensions/...

If we're using an idl value, we could put "action", "type", "data", and "extras"
in it, as for the Alarm type, right? We couldn't pass any serializable JS
objects, but it'd give quite a bit of flexibility for passing text. Or is this
facility something different?

My understanding is that the IDL or JSON provides some nice autogenerated code
for you, which makes creating these kind of parameters easier. It doesn't change
what can go in them.

I am working on adding a FileEntry as a data parameter to the intent, which will
happen in js with some extension hookery.

[benwells, 2012/05/18 03:36:02]

I've added the launchData field into the json, but I'm not using the handy
structure - the data format here is different to what gets delivered to the app,
being transformed in a custom event dispatcher.
