How AIF Builder works with different languages

The files that must be supplied, and the files that AIF Builder generates are different for different programming languages, as summarised below.

Files for an application must be located in a directory \System\Apps\app_name\, on any drive, where app_name is the application's name.

When you are working on the Emulator:

• for C++, this directory is created automatically when the application is built

• for Java, you should create a suitable directory manually yourself. Any name may be assigned to app_name — there is no requirement that it must have the same name as the class or jar file

• for OPL, this directory is created automatically when the application is translated

When an application is deployed on a target device, the application directory is created as part of the installation process.

C++ application writers must supply:

app_name.app file The application app_name.rsc file The application's resources

AIF Builder generates:

app_name.aif Application Information File .mbm Optionally, a multi-bitmap file for the application icon

Java application writers should provide:

jar, zip or class files The Java application’s code. One class must have a valid main() method. These files do not have to be located in the application folder, but this is usually most convenient. See How to set the Java command line for details.

AIF Builder generates:

app_name.app Contains a unique identifier (UID) for the application app_name.aif Application Information File app_name.txt A text file giving a command line for the Java runtime .mbm Optionally, a multi-bitmap file for the application icon

OPL application writers should provide an OPL source file (.opl) or text source file (.tpl).

AIF Builder generates:

Modified source file The original source file, with a modified app construct recording the properties of the application. Any existing app section is overwritten. .mbm Optionally, a multi-bitmap file for the application icon

Note that to complete creation of the application you must translate the source. This creates the application directory and .app and .aif files.
