If an app has an app cache, we should download and install those files at install time if possible.

From felipe, instructions on using this. We need to pass the install path to confirmInstall:

I think we can just move our Webapps:Install message to before confirmInstall and have it return to us the correctly profile path.
Attached patch Patch v1Splinter Review
This does our work finishing the install in Java before we call confirmInstall. That lets us pass the profile path from Java back to Gecko, and then on to the WebApps backend. I'm still using the webapps-sync-install notification to show a notification to the user that the webapp was installed, but the shortcut icon will be created early on. (It also fixes our character encoding problems from bug 766604, but only because it cheats).

Hoping fabrice can make sure I did the cache bit right. mbrubeck for the fennec bits.

We could pass in a listener to be notified when the cache is downloaded. Then we could break the java install flow in two. First set up the profile in Java. Send it back to Gecko. Once Gecko has downloaded the cache, set up the desktop shortcuts and show a notification. I want to avoid the extra code complexity for now. Worst case downloading the cache takes awhile and the user starts the app without waiting (I think?)

First time I have seen this. I think getResponse is too generic of a method name. Can we open a new bug to change this to getEventResponse ?

There is no downside to making the icon before we confirm the install?

> There is no downside to making the icon before we confirm the install?

There is some risk. confirmInstall copies the (already downloaded and installed) manifest into the profile. If that fails I think about:apps might have some issues, but in general the app should still work. TBH, since the apps don't have access to the manifest and I don't anticipate people using about:apps as a launcher, there isn't a lot for the platform to do for our installs. Most of what it is doing is support for stores on the web and payments stuff.

Using Fabrice's test app at to install a web app utilizing app_cache, this definitely doesn't work for me. I did the following STR:

1. Installed the app with appcache (foobar)
2. Killed my data connection
3. Started up foobar

Result - I got a server not found error.

Resolution: FIXED → ---
Are you sure you let enough time to download the app cache?
This works fine for me on mozilla-16 and mozilla-17.

Probably not. It worked for me the second time I tested it.
