Connected Limited Device Configuration (CLDC), a framework for Java ME applications targeting resource-constrained devices.

A profile comprises libraries specialized in the unique characteristics of a particular device class.Īll Java ME-enabled mobile devices currently support the following configuration and profile specifications:.

A configuration defines the minimum Java VM features and library set for a horizontal family of devices - that is, devices with similar processing and memory limitations, user interface requirements, and connection capabilities.

Java ME supports cross-platform development through configurations and profiles: Java ME runs on top of a kernel-based virtual machine (KVM), which allows reasonable, but not complete, access to the underlying device’s functionality. This subset of the Java platform provides a certified collection of Java APIs for developing software for resource - constrained devices such as cell phones, PDAs, and set - top boxes. We summarize the results from all sources in a table and conclude with our assessment of how appropriate the different platforms are with respect to critical application - development requirements. We describe the general results of this comparison as well as details from the game application’s development. Most importantly, we developed a simple game application and implemented it on all four platforms as a case study for highlighting the main characteristics and relative merits and shortcomings of the four platforms. We based the comparisons on data from earlier research, technical specifications, white papers, and an informal survey of 32 mobile - application developers with hands - on experience using the plat - forms we reviewed. To illuminate the status and trends in current development platforms, we re - viewed and compared four popular mobile - application runtime environments with respect to various quantitative and qualitative criteria. Although the choice of development platform is largely market-driven, it also depends on the characteristics of available platforms and the requirements of particular applications.

Content developers can work with audio, video, multimedia messaging, and Flash to create rich and compelling mobile content. Current tools offer application developers options to use various technologies - for example, Java, Open C, Python, Flash Lite, XHTML/CSS, JavaScript, and Mobile Ajax - to implement highly functional mobile applications.

Mobile devices have steadily gained acceptance as a multimedia platform. This article first appeared in IEEE Software magazine and is brought to you by InfoQ & IEEE Computer Society.
