Detailed explanation of the basic technologies you need to know for App development

This article gives a brief introduction to App for novice users. First, we must understand what types of Apps there are and what needs different types are suitable for. Users can choose different App development according to their own needs.

What forms does an App have?

WebApp: Simply put, Web App is a web site optimized for iOS/Android. Users can access it without downloading and installing it. . General web site weight measurement uses web technology to display on the mobile terminal, including text, video, pictures, etc., while Web App focuses more on "function". It is an application developed based on web technology to implement specific functions and must rely on the mobile browser to run. Web App development costs are low, maintenance and updates are simple, and it supports cloud repair. Users do not need to download updates. However, the user experience of the App is insufficient, page jumps are slow or even stuck, page interaction dynamics are inflexible, and it may not be available on the App Store. If the core of the enterprise There are not many functions. App requirements focus on basic functions such as information query and browsing. You can choose Web App.

Native App (Native App): Native App is an App written and operated using native programs based on the smartphone operating system (now the mainstream ones are ios and Android). Native App runs based on the local operating system, so it has better compatibility and access capabilities, the best user experience, and the best interactive interface. However, it is also the most difficult App to develop, with the highest development and maintenance costs.

Hybrid App (Hybrid App): refers to a hybrid App that is half native and half web. It is developed using both web language and programming language. It is packaged and distributed through different app stores. Users need to download, install and use it. Hybrid App combines the good user interaction experience of Native App with the advantages of cross-platform development of web App. Because web language is used in the development process, the development cost and difficulty are greatly reduced. Native App is now the mainstream application, and large-scale Apps such as Taobao/Pocket Baidu/WeChat all follow the Hybrid App route.

2. What technologies are needed to develop different types of apps?

Web App: The built-in browser of iOS/Android is based on the webkit kernel, so when developing webApp, most of them use html or html5, CSS3, and JavaScript technologies for UI layout to make it appear on the website page. To implement traditional C/S architecture software functions, server-side technologies use Java, PHP, and ASP. There are also many platforms for one-click generation of webApps, such as Baidu siteApp/mobile development platform APICloud. The APICloud platform provides webApp generation based on the Tencent x5 browser engine, because the super traffic portal WeChat/mobile QQ on the mobile side also uses the built-in browser of Tencent x5. , so the App generated using Tencent x5 browser is adapted to the WeChat browsing experience when displaying mobile pages, which can help the webApp attract traffic.

Native App:

Developing Native App requires using different development languages ​​according to the mobile phone system it is running on. The development language required to develop Android App is java, and you also need to be familiar with Android. environment and mechanisms. The main knowledge points are as follows:

1. Development environment, Android Studio, eclipse. How to build an Android development environment can be found on Baidu.
2. Data structure, some functions of the App involve algorithms, so a certain mathematical foundation is required
3. Android SDK, API interface development, including the ability to develop APIs by yourself and call third-party APIs experience of.
4. Be familiar with tcp, IP, socket and other network protocols
5. If it involves servers, you also need to understand webservice related knowledge and corresponding development languages. Commonly used ones include PHP, JSP, ASP.Net.
6. In addition to these functional foundations, App development also involves UI design, framework, performance optimization, debugging and adaptation, etc.

Objective-C is the mainstream programming language for developing iOS system apps. Developers generally use Apple’s iOS SDK to build a development environment. The iOS SDK is an indispensable software development kit for developing iOS applications. It provides Tools are needed from creating programs to compiling, debugging, running, testing and other development processes. To learn iOS development, you can read Apple's official documentation, which is the most authoritative iOS tutorial.

Hybrid App: The mainstream of hybrid development is web-based development, that is, a hybrid App development type written in web language and interspersed with Native functions. The web languages ​​mainly include html5, CSS3, JavaScript. The user experience of a Web-based App depends on the interaction and cross-platform capabilities of the underlying middleware. There are many excellent development tools at home and abroad, such as foreign AppmAkr and Appmobi, and domestic APICloud. The underlying engine of APICloud uses Deep Engine, which uses the semi-translation principle to translate the running web into Native API, and supports extended API and development Function modules developed in native languages ​​can be called at any time to achieve a user experience comparable to native Apps while saving development time.

For enterprises, they can choose different development types and development tools according to their own needs. At present, Hybrid App has become a mobile development trend. On the one hand, Hybrid App is not used or mostly not used in development. Native language can have the characteristics of native applications. On the one hand, with the development of web technology, Hybrid App technology has matured. Many large-scale Apps such as Taobao, WeChat, and Ctrip belong to this development model. Hybrid App provides enterprise mobile application development, Maintenance and updates bring extremely high convenience. Considering the cost and user experience, Hybrid App is the first choice.
