ne of the biggest challenges of writing software for mobile devices is creating user interfaces that work across a number of devices. As an application is deployed from device to device, developers face challenges due to changing environment parameters and device specifications. Screen sizes and pixel resolutions vary. Some devices are monochrome, while others support color. Some devices have two softkeys (keys on the device keypad that map to application commands) for user input, others have three—or perhaps one softkey and a scroll wheel to move through a list of options.

MIDP strives to solve these problems by providing a framework and a collection of user interface controls. These user interface APIs are found in the javax.microedition.lcdui package.
