Class Description

Class Overview

Class Goals

• Understand the Java Micro Edition architecture, and the stacking of virtual machine, configuration, and profile to address different types of micro devices.
• Understand the mission of the Mobile Information Device Profile, and see how programming for mobile devices is fundamentally different from Java SE programming.
• Build a simple, functioning "MIDlet."
• Understand the framework for packaging and deploying MIDlets to devices.
• Build user interfaces for mobile devices, including text presentation, graphics, keypad and pointer event handling, and multi-screen navigation.
• Save and re-load information from one MIDlet run to the next using the MIDP Record Management System.
• Make HTTP network connections from the mobile device.
• Use multiple threads and MIDP timers effectively.
• Manage memory usage conservatively in MIDP applications.
• Deploy completed MIDlet suites to mobile devices over the air.
