Design Of Android-based Financial Management System APP

With the gradual development of China's economy,China's personal private property is also constantly accumulating,and more and more people have begun to generate financial awareness.People are no longer simply storing money in banks to collect interest,begun looking for investment methods with higher returns.At present,the most common investments are securities,funds,futures,precious metals and many other financial services.With the development of the mobile Internet,how to use this emerging technology to provide users with more convenient financial services will be the focus of future financial industry research.This article designed a Android-based personal finance system,which can provide users with convenient handheld financial management,allowing users to grasp their own financial services business dynamics anytime and anywhere.The main modules of the system include personal finance,billing,statistical management,memorandum,calculator,and stock information.Personal finance is the core subsystem of the system,the other five subsystems are auxiliary function systems.The personal finance subsystem consists of six modules: user information management,wealth management product inquiry,held wealth management products,wealth management product purchase,early redemption and transaction details.The system can make detailed records of the user's consumption in a flexible manner,perform statistical management of the user's annual income and expenditure,and perform investment management on the remaining assets.At the same time,according to the user's habits,other sub-functions have been added to provide convenience for users to save time,better manage personal assets for users,and master asset dynamics.The system uses the MVC design pattern to design the overall architecture of the system,uses intent to implement message transmission among various activities,uses the Adapter adapter to load data,and dynamically displays data to the user interface.For the security of the UI main thread,use the Handler class to help the newly started thread periodically change the UI component's property value.Considering the ANR(Application Not Responding)exception caused by UI thread blocking,use the AsyncTask class for asynchronous processing.Finally,the system allows the server and the client to interact with each other by setting up and using an Apache server.
