Abstract:With the popularity of the Internet and smart terminal, People's daily life is becoming more and more intelligent and Internet, Especially smart mobile phone users is huge, People are increasingly dependent on the interoperability of intelligent mobile phone, The amount of information is huge every day, This requires proper management and use of these information, But Android itself has not a file manager, This will bring inconvenience to users.This topic on this issue and Contact the actual demand to design a Android APP to helpe people to facilitate the processing and management of local documents, I carried out investigation, Demand analysis and Performance analysis on this issue,In order to facilitate project development and amended, The code follows the "high cohesion and low coupling" principle, Combined with the characteristics of Android system and the demand analysis to design of each sub module function, this Subject is written in languages of Java and developed at Eclipse&ADT but run in Huawei device, it operating normally, SD card information can be read and displayed.
