Application Guidelines
application lifecycle
Start
• respond correctly
to lifecycle events
Normal Hidden
(Active) (Inactive)
• failure to do so can:
Thumbnail • drain battery
(Active/Inactive)
• interfere with other apps
Exit
Application Guidelines
applications can integrate with the operating system and
other core applications by using:
• BBM Framework,
• Share Framework,
• PIM APIs,
• Universal Search, Integrated Social Beautiful
• Push Service,
• Payment Service,
• Advertisement Service
• Balance
BlackBerry 8

9. moosecon - @KLAJLI & @ARDIRI
Application Guidelines
applications can use the Invocation Framework to minimize
“reinventing the wheel” and improve the user’s flow:
• cards and content viewers
• launching core and 3rd party Apps
• registering URIs and MIME types
Bound Invocation

open this .doc
file.

BlackBerry Platform Services
the BlackBerry Platform Services (BPS) library provides an
application with a single consistent interface to a number of
different services during the execution of the application.
• universal event management
• user interaction/navigator
• input/output (sensors, audio, LED, screen, multimedia)
• device information, locale and payment services
• network status and geo-location

You can choose!
No difference between UI created in QML or C++
They can be combined
Typically, UI in QML and business logic in C++
QML supports JavaScript for signal handling
