What is the realization principle of distribution function in the process of app development? What technology is used?

Zhejiang Tianer Software Technology Co., Ltd., you can look at the avatar connection. After more than ten years of development experience, you have summarized the knowledge that should be paid attention to in developing an APP. You can refer to it as follows: 1. Pre-demand planning and information-you need to work out a complete demand document, function document, flow chart and sequence chart. 2, interactive design, UI design-design a basic and perfect prototype diagram and the interactive design effect of app foundation, and then design a complete UI interface according to these and learn to cut the diagram. Some material pictures that need to be adaptive need to be patched. Here you also need to know the conversion between px, pt and dp, the conversion of screen density and the coefficient between them, so that your app can perfectly adapt to different resolution devices. Among them, interactive design requires you to know a lot of skills and experience in man-machine operation, master the use of interactive tools such as Axure, and UI design requires you to master Photoshop and Illustrator. 3. To develop app software in a development environment such as ADT, you must master the java language and be familiar with the android environment and mechanism. 4. If it is not a stand-alone app and you need to use a server, you have to master the relevant knowledge and development languages of WebService, such as ASP.Net, PHP and JSP. 5. Be familiar with and be able to develop databases. 6. Some functions need to be algorithmic, which also requires certain professional knowledge, especially the foundation of mathematics. 7. Be familiar with API interface development, including your own ability to develop APIs and your experience in calling third-party APIs. 8, familiar with TCP/IP, socket and other network protocols and related knowledge. 9. Proficient in the process of App release, real machine debugging skills, certificates, packaging and shelves. App development is not necessarily suitable for one person, and it is too laborious. Unless it is a stand-alone version of a small application, or a simple third-party application is developed by using a ready-made app, a team is still allowed to complete their respective areas of expertise.
