In Mobile Designer you can cross compile your mobile application's Java code into C++, C#, or Java. Mobile Designer can then compile the application code using the native tools that were installed with the target platform’s SDKs. Mobile Designer then links the compiled code to the libraries installed with the SDK. When building an application for the target platform, the relevant target-platform SDKs must be installed and configured. For more information, see Setting Up Platforms.

You can use the run-time classes described in the webMethods Mobile Designer Java API Reference to provide a wide array of features found on mobile devices. To handle device-specific differences, Mobile Designer provides the device profile database, the classes, and abstraction layers, to provide a consistent base for building your application. The abstraction layers provide the ability to load images and sound, detect interruptions, and handle text, as well as other functions, such as to establish an HTTP connection.
