Shazron Abdullah commented on CB-39:
------------------------------------
This is a question, not an issue - and thus will be closed.
Answering the question - no, JavaScript execution is paused and all network
connections are dropped. Only certain Obj-C calls can be "run in the
background" based on settings in the app's Info.plist
No, the js does not need to be re-initiated - the flash you see might be a
memory issue where a resource was released, then reloaded (image etc) - but
that's just my guess.

> by: https://github.com/gregavola
> Hello,
> I don't know if these is the right place to log this - however this is purely
> a question of what happens to PhoneGap apps when the app is in the background.
> Does the JS still continue to work when the app is placed in the background?
> I've seeing a lot of errors for JS file uploads stopping after the user
> pressed the home button during an upload.
> What happens when the app resumes? Does the JS have to be re-initated? For
> example - I use iScroll in my app, and everytime I load it back up from
> running in the background, the UIWebView flashes (almost like a partial
> reload) and continue. If I change the orientation of the device, it doesn't
> do this action - only when you try to resume. Is this PhoneGap thing or
> iScroll thing? Has anyone seen this issue?
> Thanks,
> Greg
