Positioning Module Android App System – Codeshoppy
The topic mainly studies how to achieve positioning display function of fixed assets and equipments based on the widely used Android mobile platform in the mobile Internet
era, as well as the server system, database system, and mobile client system which are used to support this function. This paper introduces the innovation of capital equipments positioning display mode on device management system. Using the new mode, the device management system can make the dynamic information of capital equipments, such as equipments operating status, device location information,
device switch status, real-time control information, real-time displayed on a mobile terminal. The research is focused on capital equipments mobile positioning display system applied to the campus environment Codeshoppy
in the development process of equipments positioning software, data acquisition and transmission of the equipments need to use data communications. Typically, network
communication of Android mobile platform has two ways, one is based on Socket, and the other one is based on Http communication protocol. The communication way based on Http protocol implements data communication by using XML or JSON as the carrier. JSON (JavaScript Object Notation) is a lightweight data interchange format. It is also a text format that is completely independent from programming language.
But it still applies to some operation habits which similar with C language, so it is easier for people to read and write. It is a subset based on the JavaScript programming languages. This means that no special API (Application Programming Interface) or toolkit when dealing with JSON data in JavaScript. Socket communication is faced with TCP / UDP protocol, which is different from Http communication. Android provides a standard java interfaces (Http URL Connection interface) and apache interface (Http Client interface) for HTTP network communication. In addition, Http communication’s data request modes have two ways, “Get” and “Post”. The amount of data transfer of “Post” is larger and the security is higher Codeshoppy
In mobile development based on Android platform, JSON and Web service are the two most important communication schemes. Under the premise of no PHP knowledge
accumulated, but has some basic knowledge of JAVA. This topic final confirms the communication way—Web service (J2EE server) + Android client.
