Headless builds for mobility projects are handled under the same principles as standard MIDP projects. If the project has already been opened in the IDE on a target computer and no reference problems exist, then any Ant target can be invoked from within the project directory. This directive determines if the file should be included in the build based on the result of the expression. Works as a standard else statement only preprocesses the code that follows when none of the previous conditions in the defining block were true. Complements inside any block started with the if/ifdef/ifndef directive.
Developing Android Apps
Works as a standard else if statement and can complement only in blocks started by an if statement. The directive preprocesses the code that follows based on the result of the expression. Determines if the line following the directive should be commented or uncommented based on the debug level set in the project properties.

An emulator allows you to understand the user experience for an application on a particular device, and to test the portability of the application across different devices. All test classes are added to a property in the JAD manifest called JMunitTestClasses. When you generate your first test for the project, the JMunit framework JAR gets added to the project libraries for all project configurations. The framework JAR builds a list of tests to run from the JMUnittestClasses property.
