Based On The Brew Mp Platform Application Engines And Optimization Of Testing Efficiency Research

With the telecommunications CDMA mobile phone continuously introduce, the original application engines no longer suitable for most cell phones, more and more defects and problems during tests revealed, the construction of new application engines is imminent. Another qualcomm BREW MP operating system launch and first using this system smartphone DuoPuDa F3188 listed erupted into high-pass smartphone market's first gun, its occurrence makes the BREW platform with new development direction, but also for the numerous BREW application transplant forward higher demands.This paper has been applied to optimize the engine, to make up for the existing application engines the insufficiency, solved the existing problem, to be suitable for most mobile phones, and can DuoPuDa F3188 on in normal operation. For application of each function:engine graphic display, resource management, Menu and elves function realization, preserving data, incoming telegram interrupt, news event handling and sound technology has made the detailed analysis and design, fixed the original application engines insufficiency, eliminating one no longer applicable and the interface technology, and gives each function modules of the concrete realization method. Introduces the principle, the realization of the menu part of the design diagram are introduced in detail, and the xquery function, another expounds on the motion process, the elves protagonist right as an example, the paper introduces the realization process of leading right away, and of which involves GunBing technology do briefly introduced. In addition, the compression and uncompress technology is analyzed, introduces Huffman coding LZ77 compression algorithm and the compression principle, solved the problem YingYongBao too. After that, the real machine test introduced encountered in the process of comparing typical problems, a cable disruptions and restore problem, font colors problem, pictures, text garbled problems such as loading and spins, and gives the corresponding solution. These methods are usually extensive testing experience summary and crystallization, and through the verification and effective method.
