Hi all,

Is there any api to run application in background like we have services in Android?

Regards,

not yet.

but you can use the InvocvationFramework to provide functionality via Cards as Viewer, Composer, Picker, ....

This application will be visible for the user, but you can open the app with a Page describing the Features of the App and that this app should only be opened by other apps through Invocation Framework

Then from other Apps you can invoke this app

The InvocationFramework will not make the App visible (if invoked as Card), so its like a Service in the background

InvocationFramework manages a Pool for your invoked app, so it can be that there are more then one instances invoked from different client apps. This is important to know if you store data in sandbox of invoked app

_NishantShah, there's a handy Forum Search feature here, which could easily answer the question. Type "background service" in the search box near the upper right corner and you should find dozens of past threads with discussions about this. There's no new information to add yet.

Technically wouldn't setting the "Run in Background" permission on the app allow the app to run in the background? I use this in my app to allow code to continue running while the user does other things.

Granted, it doesn't keep the app running if they explicitly quit it, if that was the question. For that, you'd need to use the push framework.

raffi, that may work for him. I didn't mention it because (a) it's in the other threads, and (b) he specifically mentioned "services". I suppose if on Android that's the only way to get *any* background ability, then it's good to point out that permission for those new to BB10.

[raffi]

Yeah, I wasn't sure about "services" either, but I figured it was just the term he knew from Android.

[_NishantShah]

Thanks for replying. I am looking for a way to keep a service running even if user quits the application.

[peter9477]

That's what I thought... so those other threads the search feature will find would have all the answers you'd ever want (except the one that says "yes, you can do it").

In this case the only way is PushService.
