Before you can test your Flash Lite for BREW applications on a given device, you copy the Flash Lite Extension onto the device. This needs to be done only once, when you first acquire the device for testing. End users of your application will receive these files as part of the download when they download your completed application from the BDS or ADS, but developers must copy these files manually. The files are listed below. Follow the instructions in the rest of this section to upload the files to your device using the AppLoader tool. Note that the locations to which you copy these files are different for BREW 2.x and 3.x devices. See Device file structures for different BREW versions for more information.
