Examples — software installation

The minimal application HelloWorld, located in epoc32ex\ToolsAndUtilities\ is used to demonstrate Installation File Generator functionality. The application prints Hello World! on the screen in English.

The application in its most basic form is comprised of two files: HelloWorld.app and HelloWorld.rsc, located in the directory epoc32ex\ToolsAndUtilities\, which must be installed into \system\apps\HelloWorld\ on the target phone. Further resource files HelloWorld.rit, Helloworld.ruk, HelloWorld.rfr are used to demonstrate more complex functionality.

Rather than manually creating this directory and copying the files into it, a sis file may be produced, from one of the package files provided in epoc32ex\ToolsAndUtilities\, to automate the installation procedure. The package files provided with the example project are as follows:

• HelloWorld.pkg — Demonstrates the most basic Installation File Generator functionality.

• HelloWorldText.pkg — Demonstrates how a text file is viewed on the PC, and a file is automatically run on the target platform, during installation.

• HelloWorldLangs.pkg — Demonstrates how to install applications supporting more than one language.

• HelloWorldSis.pkg — Demonstrates how an installation file bundles other sis files.

• HelloWorldOptions.pkg — Demonstrates how to use an options line and condition block in an installation.

• HelloWorldSecure.pkg — Demonstrates the use of a package signature for secure installation.
