Research And Development Of Mobile Application And The Inner Purchase System

The rapid development of mobile terminals has brought prosperity to mobile application market.Users’demand of function and performance for mobile applications is growing.Meanwhile, inner purchase has become the main way to get profit in applications.Therefore, research and development of mobile application and the inner purchase system has important practical importance.Based on the Android platform, this paper designed and implemented an efficient mobile application development engine embedded with inner purchase system.This paper first introduces the fundermental knowledge of Android platform, which deeply involves with the development of mobile application engine, including the system architecture of Android platform, the application component and the life circle of Activity.Then this paper introduces the HTTP protocol which will be used in the development of inner purchase system’s network communication.One of the main purpose of this paper is the design and implementation of a mobile application engine.Firstly, this paper makes needs analysis of the application engine.And according to the needs, this paper designs the program flow and operating mechanism of the engine and then makes systematic devision of the engine according to the function.The engine is divided into several parts, including loading module, graphic module, iteract module, move and collide module, map module, storage module and sound module.Then this paper focuses on the implementation process of these various functional modules, and make comprehensive and detailed description of the class diagram, operating principles and implementation processes of each functional module.The other purpose of this paper is the design and implementation of the inner purchase system.Made design and implementation of both the client program and server program of the inner purchase system and finally embed the system into the engine designed befor, and orders interface to developers to implement purchase function.
