Now I can use Invoke.invokeApplication() to invoke a system application in blackberry, such as Messages, Calendar, etc.
however, I don't know how to launch "Files" application, which managers files of blackberry smartphone, and locate to a desired path.
could you kindly give me an answer? thanks a lot!
here is a link that describes how to invoke a BlackBerry® Device Software application, such as the contacts application, the phone application, and the media application.
