Design And Implementation Of File Manager Based On Android

Trend with the development of modern science and technology, mobile Inte rnet technology rapid development, all kinds of mobile terminal based on the technology of communication equipment is becoming more and more good.To further improve the technology of electronic products, upgrading operating systems, a lot of smart phones are into our lives. Android phone as the number of users the most widely used smart phones, more and more been used in various fields.With the popularity of mobile phones, a variety of popular applications are also being transferred from the table to our pockets, it also makes a lot of location-based positioning program is not limited to the use of the keyboard but the use of sensors, a lot of practical applications unprecedented potential. It gradually expanded application needs, a lot of growth in the mobile phone store photos, audio, video, and data, so have a good document management software is imminent. Currently Android platform development more perfect, a substantial increase in the number of users. Design and implementation of a benefit of the Android user file management software is necessary.In accordance with the actual requirements starting from the economy, reliability, security, three aspects to consider in detail the development of the development needs Android file management software. This paper examines the current situation of Android file management, file management business process analysis, system requirements and detailed instructions and then use the MVC design pattern, from the use of software functionality, an application of the ove rall design.Android application development technology specific binding, detailed description of the interface design, realization various file operations are handled Android asynchronous tasks. Finally, it guarantees a good user experience, realization of the file system browsing, file management, and other basic operations functions.This article describes the development of a file management system is based on Google’s Android operating system release, the development language used is Java, the interface uses XML layout, and resource files, and the code has been done separated. After the detailed design and implementation, this paper gives the various functions of the system test, and system performance was evaluated test, the overall test results in line with expectations, to meet the requirements of the system.In addition, the capacity removable storage devices are limited, if they exist anywhere on the network and can be taken out, so it is very convenient. To meet this demand, but also designed a document management client, in order to accelerate the upload and download speed, we take parallel transmission policy, allows mobile phone users to access files on a remote server the same as with local access.
