Download Developing Software for the QUALCOMM BREW Platform by Ray Rischpater (auth.) PDF

By Ray Rischpater (auth.)

QUALCOMM Binary Runtime setting for instant (BREW) is a improvement platform permitting software program builders to create functions that function on all handsets using QUALCOMM CDMA chipsets. This state-of-the-art publication introduces BREW and describes alterations from product opponents like J2ME, Palm OS, Symbian, and Pocket computing device cell version.

BREW bargains a few key merits over different software program environments, like safe program licensing, built-in billing, and down-to-the-metal APIs for high-performance purposes. you will examine what it takes to enhance purposes for BREW—not simply improvement instruments, however the method required to carry an program to a service for distribution.

Over 1 million BREW-enabled handsets shipped in the course of BREW's first 12 months. And BREW is concerned with either significant family vendors (such as Verizon instant, boasting over 37 million subscribers) and in another country providers. therefore, BREW is poised as a key participant within the instant handset area.

Sample text

C file contains a set of utility functions and the necessary wrapper to enclose your application inside an instance of the IApplet class, which is the root class for all applications. c file contains a set ofutility functions and the necessary wrapper to enclose a module inside an instance of the IModule class. Under normal circumstances, you won't need to change either of these files; however, as you learn more about QUALCOMM BREw, it's instructive to take a look at them. NOTE The application's event handler, HelloWorld_HandleEvent, needs to handle only two events: EVT_APP_START, which the shell sends when the application first launches, and EVT_APP_STOP, which the shell sends when the application ends.

The SIG file is a unique, cryptographically signed file that contains information from QUALCOMM and your handset's unique Electronic Serial Number (ESN). Although all of this may sound like a needless headache-especially in comparison with competing smart phone platforms-these obstacles serve a necessary purpose. By restricting handsets so that only QUALCOMM-authenticated developers can run applications and requiring a SIG file for each handset, QUALCOMM maintains the integrity of the BREW download mechanism.

For example, when you add an icon (or an image or thumbnail image, through the dialog box you access by clicking the Advanced button on the first tab), the images are added to the MIE Thus, if you want to use the information in another file, you need to use the corresponding Extract button to recover the information in a separate file. As you'll see in subsequent sections, what you name your MIF is very important. Your MIF must be named the same as your module-the Dynamic linked Library (DLL) and Module (MOD) files-so that the system can correctly associate the module information with the module.
