multi application.

hi everyone,

how to switch to another application, while the last one still running and working.

i want the camera recorder keep recording while i lock the device, or just switch to home screen.

i think that the camera recorder app cost much cpu and memory, so can not do any other task while recording, but i just want to lock or switch to home screen.

 

regards,

Khanh Le

Re: multi application.

First thing to do is to try to see if you can actually do this.  So press and hold the BlackBerry key, select the Home screen, and lock the device.  Reverse and see if the Video is still running.  I think you might find it is not.

Re: multi application.

of course, the video recorder will stop when press the lock button or switch to another app. I mean can we  write an application to prevent this happen?

Re: multi application.

I think you can safely say, from the lack of replies, that no-one here knows how to do this, or if it is even possible. 

 

There is no API that I am aware of to help either. 

 

Sorry.

Re: multi application.

so. the proplem come from the those that made the API, and the Blackberry core..

i think i should give them an email suggestion that we have to change and make some thing new(different) for Blackberry device.
