Eclipse with his rich set of plug-ins is a natural choice for IDE when developing mobile application. But most of the tools for Eclipse in the area of test and optimization are provided only for desktop platforms. Usually there is a big difference in the application behavior when running on simulator and on the mobile device because of the different memory and CPU usage. In an ideal case the applications designed for resource-constrained mobile and embedded devices should be profiled directly on those devices.

Most of the current profilers are built in on top of the Sun's JVMPI interface (Java Virtual Machine Profiler Interface). To use this approach for java applications running on a target embedded system it is necessary to design a profiler agent which consumes minimal system resources so that it does not influence the application behavior.

This talk will concentrate on design and development of the profiling tools and their usage in mobile application development.

Some themes of the talk are:

• Java Virtual Machine Profiler Interface (JVMPI)
• Local and remote profiling
• Memory Profiling
• CPU profiling
• Visual representation and statistics (VM Load, GC activities)
• Profiling real application on Symbian OS – problems and solutions

At the talk will be discussed limitations of current eclipse Tracing and Profiling Tools Project (TPTP) and requirement about profiling java applications directly on mobile device.

The talk will include live demo for profiling of mobile java application on Symbian OS in Eclipse IDEs using JProfiler – Java Profiler Eclipse plug-in for Windows, WinCE, Linux (desktop and embedded), Symbian, QNX and VxWorks.
