Right that was it, I thought it had something to do with it being in the background but it was a simple mistake.
Fixed it now looks much nicer

This sounds to me like somehow the callbackIDs are out of sync. missing a
keepCallback?
... is there a window.onerror js handler to see what is actually happening?

That is odd, if calling into JavaScript from being in the background works,
the pluginResult method should work as well. Might be worth investigating

Hi Shazron,
Actually I started out building it this way, I’ve changed it to way it’s now, because it didn’t work. Once the application has moved to the background trying to invoke the method with the plugin result no longer works. I’ve seen other plugins use the ‘named’ callback ’trick’ and thought that was the way to invoke a callback from background. Shall I try to investigate why this is not working?
Cheers,
Erik Jan

Hi Erik,
The gist of it is here:
http://cordova.apache.org/docs/en/3.4.0/guide_platforms_ios_plugin.md.html#iOS%20Plugins
Basically, you have to modify your js interface to take in a success and
failure callback. Then, in native code you create a PluginResult and set it
to a specific command status (CDVCommandStatus_*), then send it back
through the commandDelegate - it will figure out how to route it properly.
There are examples in the link above.

Joe - this calls a background fetch handler for your app at an interval, it
doesn't really run in the background.
Erik - just a quick code review:
1. The method swizzling stuff is great but what I have planned (sometime in
the future, in progress) is this:
https://issues.apache.org/jira/browse/CB-5601
2. The way you are using callbacks is not quite correct
Agree on it being a user space plugin -- but I was thinking it could be in
cordova-plugins maybe when the time comes

Is this actually running a service? I thought this just runs a
Cordova App in the background, which Android already has a setting
for.

I think its cool as a user space plugin for now though. Have you published
it to http://plugins.cordova.io ? (Its just like npm / you can read up on
how here: https://github.com/apache/cordova-plugman)
I really like the idea of us looking at background processing.
Android services: how would that work? Does Firefox OS have the concept of
background services? I know Chrome Mobile Apps guys have been doing some
thinking here too.
