Hello BlackBerrians,

Can any body have any idea about, the upcoming BlackBerry 10 OS having support for background running application without having user interface??

Regards,

Dinesh

not initially, but in a later release (which could take some time).
RIM wants us to use listeners/events for most things right now.

hi simon,
thanks for reply. I think it will be too late if they are not providing this functionality with first release. I have more than ten of application, which made for os 5.0 to os 7.1, they all having background process without showing user interface. I want to make them compatible to os10.

i would guess that most things that needed a background process in bb java are possible without one in bb10.
maybe you can list your usecases?

Yup, I am also interested in above..

Simon's right, that you need to identify the specific use cases you have. What is your app actually achieving by running in the background? Their goal is to provide system services, primarily leveraging the Invocation Framework and Push Service, to support most of the "background" requirements.

Only after they've dealt with those will they take the final step and actually implement true "background service" support for third-party apps, and the one thing we do know is that they don't plan on doing that BEFORE the launch of BB10 (at least for now).

It's in your best interests to clarify your specific needs so we can see whether there are alternatives and, if there are not, to add to their list of cases which are not yet handled well.

Yes, but it will have a special permission and go through a lengthier app approval process because they will want to verify if its absolutely necessary that you run in the background.

See here for the permission, works with current public BB10 build.

If you provide us with how you would use it we can maybe suggest an alternative.

HuXu77 that's not the same thing... Your app still has A UI when you use that permission... It just means the OS keeps sending you events when you use it, instead of freezing as if it's in standby.
