Enhanced User Interface

MIDP 2.0 enhances the overall end user experience, improves application portability, and provides greater extensibility.

Many new features make MIDP applications more interactive and easier to use, including several enhancements to Screens and Items. Some notable examples:

A new Popup ChoiceGroup shows a current selection in a box with a visual cue. Scroll down and other items "pop up."
Items have their own sets of commands that can be invoked, as well as the ability to add new commands. For instance, String Item and ImageItem can be made more interactive by adding an abstract command and set the appearance mode to show as a hyperlink or a button.
Alert Screen can now have abstract commands added to it to enable developers to use this screen to ask users questions. Gauges can be added to Alert Screens.

In addition, MIDP 2.0 provides a more flexible layout for greater application portability. Form Screens now provide developers more control of screen layout by the mobile device's MIDP implementation based on the display size and other attributes. Individual Items within Form Screens also now have minimum and recommended size. Each MIDP implementation uses the layout and Screen and Items attributes to optimally lay out the application.

MIDP 2.0 also provides greater extensibility. One notable addition is Custom Items, a new Item developers use to create their own Form Items such as map viewers and other custom UI components.

Media Support

MIDP 2.0 now includes the the Audio Building Block (ABB) that is also part of the Mobile Media API (MMAPI), an optional package for MIDP 2.0. ABB enables developers to add audio such as tones, tone sequences and WAV files to MIDP applications without relying on MMAPI. On devices that also include a MMAPI implementation, developers can add more multimedia content to their MIDP applications such as video streaming.

Game Support

MIDP 2.0 adds a Game API that provides a standard foundation for building games. The MIDP Game API includes game-specific functionality, such as sprites and tiled layers, that take advantage of native device graphics capabilities. This functionality simplifies development and provides greater control over graphics and performance.
