Short description As the number of mobile phones continue to increase, there is a growing market for increasingly sophisticated consumer or enterprise applications and services on Symbian OS phones. Symbian OS is widely perceived, though, to have a steep learning curve. Written by Symbian developers, Common Design Patterns for Symbian OS is the first book of design patterns for Symbian OS, which allows users to find solutions to common design and architectural problems often experienced when creating applications and services for Symbian OS. Applicable to all Symbian OS phones from v9.1 onwards, with many patterns applicable to earlier versions of Symbian OS, this indispensable guide enables readers to write sophisticated programs quickly and to a high standard.
