Written to address technical concerns that mobile developers face regardless of platform, this book explores the differences between mobile and stationary applications and the architectural and software development concepts needed to build mobile applications. Using UML, Reza B'far guides the developer through the development process, from design to implementation. He focuses on general concepts, while using platforms as examples or as possible tools. After introducing UML, XML, and derivative tools necessary for developing mobile software applications, B'far shows how to build user interfaces for mobile applications. He covers location sensitivity, wireless connectivity, mobile agents, data synchronization, security, and push-based technologies, finally homes in on the practical issues of mobile application development including the development cycle for mobile applications, testing mobile applications, architectural concerns, and a case study.
