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.
assuming that this is the upper limit of objects, an index of only 8 bits can be used. Furthermore, it is possible to check that there will be no invalid indexing. Linear memory allocation often requires that memory is reserved in advance, at least partly. It is then possible to use the already reserved objects later in the user program. This gives rise to some related basic principles to consider. 2.3.2 Basic Design Decisions In the following, we introduce some basic principles helping in using
can be used to describe attributes of applications, such as language settings and structural properties including menus, for instance. 3.3.1 Event-Based Programming A commonly used approach to the programming of a graphical user interface is to allow every GUI element to generate events. For instance, when the cursor moves over a button, an event can be generated. Similarly, a button click can bear special signiﬁcance only when executed over a certain graphical element depicting a button. This
plugin. When the message is received, the receiving device must recognize that the incoming message requires an MMS plugin, which is then loaded, and used for displaying the message. The confusing part is what happens if the user decides to reply to the MMS. As the MMS plugin is already loaded, the user may not be prompted about the message type but the present plugin is used automatically, which is the fastest and probably the most convenient way. As a result, it may be impossible to respond to
instance some hardware resource is initiated, it is possible that version-speciﬁc variations as well as differences in emulators and devices imply difﬁculties. For instance, the sample server given by Stitchbury (2004) contains code that is different depending on the used environment due to the differences in threading models in the emulator and the actual device. Further complexity is added to the scheme when addressing the use of services, whose execution is preferably asynchronous. Then,
design block to be ﬁtted in the device, and it requires more energy to run than a single-purpose piece of hardware. Still, in general, DSPs have superior power consumption to 8 Programming Mobile Devices performance rate over general purpose processors in tasks that are well-suited for them. As an example, a study has shown that a typical signal processing task on a RISC machine (StrongARM, ARM9E) requires three times as many cycles as a C55x DSP while consuming more than twice the power
