Lab-5539: Touch your application! - Building slick, touch-enabled UIs for Java ME

Last Updated: April 10, 2009

During this hands-on lab participants learn about rich UI development for Java ME based touch screen devices. This hands-on lab also explains the architecture of Rich SVG UI widgets and shows how they help speed up the process of designing slick UIs for touch screen devices. During this hands-on lab we discuss the most common scenarios for this type of UI development illustrated by source code examples as well as UI screen shots and schemas.

The target audience for this session is the rapidly growing number of developers for large, Java ME based touch screen devices like the Samsung Omnia and Instinct, Nokia 5800 Xpress Music or Blackbery Storm.

Attendees can take the application home in their phones at the end of the hands-on lab. The application will work on most devices that support the SVG API for J2ME (JSR226) since Rich SVG UI widgets are also supported by devices without touch screens.
