Summary:
Mobile smart terminals equipped with Google's Android and Apple's iOS operating systems have developed rapidly in recent years, and they have high-speed computing and processing capabilities and excellent interaction methods, and are now the most important mobile computing platforms. People can do all kinds of things on it anytime and anywhere, such as instant messaging, writing documents, shopping and spending. At the same time, people's payment methods have also changed, mobile payment has gradually become the mainstream payment method, but this has also brought us some negative effects, the main point is that due to the convenience of mobile payment, young people do not know how to consume rationally, can not manage money well, which has brought a lot of trouble to our material life. This is where the mobile-based personal accounting system comes in.
Based on the analysis and discussion of the technical principles of Android mobile phone software development, this paper designs and implements a mobile phone accounting system based on Android platform. The whole system is divided into three layers: the presentation layer, the business logic layer and the data storage layer. The presentation layer primarily uses Android UI technology to display data; The business logic layer is mainly responsible for the management and control of business logic and operation processes. The data storage layer uses the SQLite database locally, and the server uses the MySQL database. The system is developed on the Android platform, and uses the J**A language to realize the functions of account management, bookkeeping management, query management, statistical analysis and data management.
Keywords j**a; android;Accounting; Mobile computing platform.
