Dsign And Implementaion Of Mobile Audio Player Based On BREW

In recent years, with the development of information technology, people areentering a new era of multimedia. Mobile phones become a significant tool of dailycommunication. Only calling function cannot meet people’s requirements, audio playerbuilt in the phones even make life more colorful. Based on specified developmentplatforms of the OS for mobile phones, the built-in audio player should be based on thespecified technology as well. The development based on BREW is widely used recently.This paper has done research on the software development of mobile audio playersbased on Binary Runtime Environment for Wireless (BREW, which is a completebusiness solution for mobile services developed by Qualcomm). Research mainlycarries out on3aspects: content, architecture, core technology of the BREW platform,and analyzed the important interface and technologies of the mobile audio player’sdevelopment on the BREW platform. According to demand I completed a player thatcan play audio files,and on this basis, I added and completed the function of audiorecording and pictures display,Paper has solved the problems encountered in theprocedure of software development,I have made optimization on the disadvantage ofmemory occupation when the Player working.I completed functional verification ofplayer with the BREW SDK tools.The test results show that the player designed to playaudio files can work normally,additional functions of recording and image display evenmeet the requirements.
