Web App: Simply put, WebApp is a website optimized for iOS/Android, and users can access it without downloading and installing it. The general website weight measurement is displayed on the mobile terminal by using web technology, including text, video, pictures and so on. And Web App pays more attention to "function", which is an application based on Web technology and must rely on mobile browser to run. Web App has low development cost, simple maintenance and update, and supports cloud repair, so users do not need to download updates. However, the user experience of the App is insufficient, the page jumps slowly or even gets stuck, and the dynamic effect of page interaction is not flexible enough, so it may not be used in the AppStore. If the core functions of the enterprise are few, and the demand of App focuses on basic functions such as information query and browsing, you can choose Web App.

Technology stack: The programming languages JAVA ios and Objective-C that Android needs to master.

1. Development environment, Android Studio, eclipse；;

2. Data structure, some functions of App involve algorithms, so it must have a certain mathematical foundation;

3.Android SDK, you can develop API interfaces, including your own ability to develop APIs and the experience of calling the third API;

4. Familiar with tcp, IP, socket and other network protocols;

5. If the server is involved, you need to know the webservice and the corresponding development languages, such as PHP, JSP, ASP.Net, etc.

6. In addition to these functional foundations, App development also involves UI design, framework, performance optimization, debugging and adaptation.

Hybrid App: refers to a hybrid App that is semi-native and semi-web. It is developed in both web language and programming language, packaged and distributed through different application stores, and users need to download, install and use it. Hybrid App has the advantages of good user interaction experience of Native App and cross-platform development of web App. Because the web language is used in the development process, the development cost and difficulty are greatly reduced.
