One of the most convenient things about the BREW SDK is the resource file. If you are familiar with Windows programming, you may already be familiar with the concept. A resource file is a suitcase stuffed with all the external data that your applet needs. Using resource files makes it easy to create custom versions for different screen resolutions or languages. Simply create a new resource file with different graphics or text strings and you can use largely the same code for multiple versions of your applet. It is also possible to use multiple resource files per applet for the same purpose. This chapter will discuss what is in a typical BREW resource file and how it is used in your code.
