Jonathan Allin presents a volume which should help Java developers quickly adapt to Symbian platforms enabling them to write high quality and efficient applications suited to a constrained device.

..".as computing moves away from the desktop and into our hands, we demand ever-higher reliability. Device manufacturers and service providers can no longer afford to think in terms of proprietary systems. They think instead of open standards and cross-platform Java technology." <b>From the foreword by Greg Papadopoulos, CTO, Sun Microsystems, Inc.</b> Java on Symbian OS is a powerful programming environment that enables fast, secure deployment of applications and services onto a wide range of wireless devices. Symbian's Java implementation gives developers access to key wireless technologies, including telephony, contacts management, calendaring, Datagram messaging and power monitoring.</p> Complete with numerous illustrative and real-world examples, this 'from-the-source' guide provides developers with authoritative, practical and timely information on: </p> <ul> <li>using the Symbian Software Development Kits.</li> <li>the JavaPhone and Personal Java APIs, and how they are implemented.</li> <li>writing efficient and optimized code for constrained devices.</li> <li>understanding and working with Java on Communicator reference designs.</li> <li>creating games.</li> <li>accessing native functionality through JNI (Java Native Interface).</li> <li>creating wireless services.</li> <li>operator and service provider issues, including security, provisioning, rapid and reliable development.</li> </ul> The book also contains contributions from Colin Turfus, Lucy Sweet, Alan Robinson and John Bown of Symbian and wireless case studies from Digia Oy (A Symbian Competence Center) and Telenor R&D.
