Understanding J2ME
• Java 2 Micro Edition (J2ME) is an umbrella term for a set of Java technologies
created to run Java on less capable devices
• Key concepts of configurations, profiles and optional packages:
• configuration = VM + runtime classes (horizontal)
• profile = domain-specific classes for building standalone applications (vertical)
• optional package = domain-specific classes that expose specific functionality but
not applications (horizontal or vertical)
BlackBerry and J2ME
• BlackBerry devices (Java-based) run MIDP and CLDC
• MIDP 1.0/CLDC 1.0 for 3.6/3.7 devices
• MIDP 2.0/CLDC 1.1 for 3.8/4.0 devices
• Custom Java VM
• Additional APIs available
• Some optional packages
• Many BlackBerry-specific APIs (vendor extensions)
• Built-in apps written in Java
• RIM eats it’s own food
Application Models
• MIDlets
• Applications built using MIDP application lifecycle and user interface classes
• Portable to other platforms unless BB APIs used
• BlackBerry applications
• Standard “public static void main( String*+ args )” entry point
• Tied to BlackBerry, but more control over the application
• BlackBerry-specific UI classes
• Can run in background (no UI), on startup, etc.
Software Stack
• Programming Language: Java
• IDE: Blackberry JDE, Eclipse

of OpenC/Symbian APIs
• Qt base libraries are compiled as
Symbian DLLs and can be used in a
Symbian environment as is
23
Qt Applications on Symbian
#include <QtGui/QApplication>
#include <QtGui/QLabel>
int main( int argc, char** argv )
{
QApplication app( argc, argv );
QLabel label("My first Qt on Symbian SW" );
label.show();
return app.exec();
}

iPhone OS overview and Technologies
iPhone Os can be viewed as set of layers
Cocoa Touch Layer
• The Cocoa Touch layer comprises the UIKit and Foundation frameworks
(UIKit.framework and Foundation.framework), which provide the basic tools
and infrastructure you need to implement graphical, event-driven
applications in iPhone OS
• iPhone OS uses this layer to implement features:
• Application management
• Graphics and windowing support
• Event-handling support
• User interface management
• Objects representing the standard system views and controls
• Support for text and web content
• Accelerometer data
• The built-in camera
• The user’s photo library
• Device-specific information
Media Layer
• The Media layer provides graphics and media technologies in iPhone OS that are
geared toward creating most advanced multimedia experience on a mobile device
• Graphics Technologies
• technologies to do your 2D and 3D drawing
• OpenGLES.framework (OpenGL), EAGL.framework, QuartzCore.framework (Core
Animation), Core- Graphics.framework (Quartz)
• Core Audio
• Native support for audio is provided by the Core Audio family of frameworks
• CoreAudio.framework (audio type and file info), AudioToolbox.framework
(playback and recording), AudioUnit.framework (audio processing)
• OpenAL
• The Open Audio Library (OpenAL) interface is a cross-platform standard for
delivering 3D audio in applications
• Video Technologies
• iPhone OS provides support for full-screen video playback through the Media
Player framework (MediaPlayer.framework)
• supports the playback of movie files with the .mov, .mp4, .m4v, and .3gp filename
extensions
Core Services
• The Core Services layer provides the fundamental system services that all applications use
• Address Book
• AddressBook.framework: provides programmatic access to the contacts stored on a
user’s device
• AddressBookUI.framework: complements the Address Book framework by providing a
graphical interface for accessing the user’s contacts
• Core Location
• CoreLocation.framework: lets you determine the current latitude and longitude of a
device
• CFNetwork
• CFNetwork.framework: high-performance, C-based framework that provides a set of
object-oriented abstractions for working with network protocols, for tasks such as
communicating with FTP and HTTP servers or resolving DNS hosts
• Security
• Security.framework: provides interfaces for managing certificates, public and private
keys, and trust policies
• SQLite
• The SQLite library lets you embed a lightweight SQL database into your application
without running a separate remote database server process
• From your application, you can create local database files and manage the tables and
records in those files
Core OS
• The Core OS layer encompasses the kernel environment, drivers, and
basic interfaces of the operating system
• iPhone OS provides a set of interfaces for accessing many low-level
features of the operating system. Your application accesses these
features through the LibSystem library. The interfaces are C-based and
provide support for the following:
• Threading (POSIX threads)
• Networking (BSD sockets)
• File-system access
• Standard I/O
• Bonjour and DNS services
• Locale information
• Memory allocation
