Advantages
Disadvantages
•
Applications are portable to other
devices that also support the MIDP
specification.
•
Applications can use only the user interface APIs that exist in the
javax.microedition.lcdui
library.
•
The model assumes that all application processes terminate when the
application closes.
•
Applications cannot start automatically in the background when the device
turns on.
CLDC applications
The CLDC application model is a specification of a framework for Java® ME. A CLDC application extends the
UiApplication
class and starts with a standard
main()
method.
Most of the sample applications that the BlackBerry® Java® Development Environmentincludes use the CLDC application model.
All of the core BlackBerry applications (including message list, contacts list, calendar, and the browser) are built as CLDC
applications.
Advantages
Disadvantages
•
BlackBerry User Interface APIs provide more
functionality and flexibility than the standard
javax.microedition.lcdui
library.
•
Applications can run active background
threads after they have closed.
•
Applications can start automatically in the
background when the device turns on.
•
Applications can use IPC APIs to exchange
information with other applications.
•
Developers can create reusable library
modules that CLDC applications can import.
•
Applications are not portable to other devices.
