Design And Implementation Of Mediaplayer Based On Android

With the development of telecommunication networks°and computer science, users of new generation have poised a higher demand for functions and performance of mobile devices. Therefore, it will be a vast future market for developing mobile application of powerful function and beautiful panel. The media player this thesis designed is based on Android platform which is nowadays fastest developed one and has widest potential market of all operating systems for smart phones.This Thesis introduced present situation of mobile software developing at home and abroad, discussed the key technologies of software developing based on Android platform, gave the details of requirement analysis on media player, and described the construct collectivity design that includes framework design, functional modules design, design of configuration file. In the detailed design of this paper, it gave description of core modules that include playing module, library module, the playback service module. In the modules, it illustrated design ideas, interactive process; communicate mechanism, message mechanism, component live cycle, and panel designing of core components which are Play Activity, PlayBackService, and LibraryActivity.The media player of this paper designed passed feature testing and performance testing, went into running stage which proves the feasibility of this solution. During the development of this software, the author participated in writing requirement document and detailed design document, developing library module. The playback service module was developed by the author independently.Through introducing the design and implementation of media player based on Android platform, the author hopes that it will be a good reference for developing more powerful function of mobile devices multimedia software.
