Learn how to programme the mobile devices of the
future!

The importance of mobile systems programming has emerged over
the recent years as a new domain in software development. The
design of software that runs in a mobile device requires that
developers combine the rules applicable in embedded environment;
memory-awareness, limited performance, security, and limited
resources with features that are needed in workstation environment;
modifiability, run-time extensions, and rapid application
development.

Programming Mobile Devices is a comprehensive, practical
introduction to programming mobile systems. The book is a platform
independent approach to programming mobile devices: it does not
focus on specific technologies, and devices, instead it evaluates
the component areas and issues that are common to all mobile
software platforms. This text will enable the designer to programme
mobile devices by mastering both hardware-aware and
application-level software, as well as the main principles that
guide their design.

Programming Mobile Devices:

* Provides a complete and authoritative overview of programming
mobile systems.

* Discusses the major issues surrounding mobile systems
programming; such as understanding of embedded systems and
workstation programming.

* Covers memory management, the concepts of applications,
dynamically linked libraries, concurrency, handling local
resources, networking and mobile devices as well as security
features.

* Uses generic examples from JavaTM and Symbian OS to illustrate
the principles of mobile device programming.

Programming Mobile Devices is essential reading for
graduate and advanced undergraduate students, academic and
industrial researchers in the field as well as software developers,
and programmers.
