Design And Implementation Of Mobile Application Distribution Systems Based On Android System

With the popularity of the network and intelligent terminals, more and more people to get information through mobile terminals, a new mobile Internet era has arrived. The emergence of mobile application software is based on the development of mobile communication networks.Firstly, This article extracting functional requirements from the users1 point of view. Which including app skimming, app downloading and app management. And then based on the analysis of the requirements, the design of the client system is completed:The system design is described by the block diagram, there are 3 function modules in this system, the design of function module is described by Hierarchical relationship and Calling relationships within these modules. In respect ofimplementation, these 3 modules is described by module function, data structure and implementation details. Each part of implementation is provided class diagram and main classes. Then the client is tested to verify the functionality and accuracy. At last, The article reviews the client system and propose further work to be done.About the key the technology, first,the paper introduces the technology including Android operating system、multi-thread dowload based on HTTP protocol and the communication between client and server; Second, in order to meet the high cohesion and low coupling of software development requirements, the system is divided into four basic parts, which also satisfies the four parts of the MVC design pattern, then achieve the basic client functions、application reaserach、application download and client receives and resolves the data sended from server. Between the mobile client software and server using JSON data format for data exchange.In summary,through the analyzes of the distribution system,the paper design and implemente the client software based on Android operater system. The client can meet the demand for users to search and download the mobile application.
