The Design And Implementation Of File Management System Based On Android

China Internet network development status statistics report latest data show that the mobile Internet has become the biggest highlight of the Internet industry development.The Android system has low the introduction of cost,good user experience,open stronger,application resource rich characteristics and adapt to the development trend of mobile Internet,has made rapid development.But the Android system itself,the platform does not provide file management functions,and with the mobile terminal of the processing power and storage capacity is more and more,for the utilization of resources and management requirements are also getting higher and higher,the Android system for file management and support shortage and households between the actual demand contradictory prominent.Development of a Android based file management system has important practical significance.This thesis designs and implements the file management system based on Android..The system development using the MVC design pattern,based on XML technology,development language for Java by the eclipse tools software as the simulation development platform,in the eclipse tools to build Android development environment to develop the system.Firstly,the paper analyzes the requirement of Android file management system,and analyzes the feasibility of the system construction..In the form of the use case diagram detailed analysis of the file management subsystem,folder management subsystem,SD card management subsystem and retrieval system,describe the use case is given in detail in the use case diagram of the system based on.Then the system launch of the design,the workflow system is designed based on the use case diagram,designs the overall structure of the system,the hierarchical design,detailed description of the framework layer,support layer,logic layer and presentation layer design process.System based on the MVC pattern of development,in the vertical according to the function of the various decomposition levels,each layer in the horizontal cut into one package,the package contains a related set of classes,the system at the same time,the package as an independent physical unit management.Rooms are independent of each other.Finally,the system is developed and implemented and tested..The system model,the view and the controller are implemented respectively,and the key code section and key display page are given..At the same time,the test of the system is given,the test procedure and the test result of the typical test case are given,and the system runs well..Android file management system design and Implementation Based on,has important significance for enhance the Android users of file management of user experience,for Android mobile terminal development has a certain role in promoting.
