1. System Overview
Android enterprise project development, as the focus of the new generation of information technology and the core industry that promotes information consumption, has become a new hot spot in the development of my country's transformation of the information service industry: it has become the fastest growing business field with the greatest market potential in the information and communication field. The Internet, especially the mobile Internet, with its huge information exchange capabilities and rapid penetration capabilities, expands new creative space through targeted integration of production factors, thus transforming or even merging the development models of traditional industries. The country has promulgated the "Internet +" action plan and implemented policies such as "Made in China 2025" to lead the development of the domestic Internet + industry. The scale of mobile Internet users has grown rapidly, driving the development of industries such as software, storage and display. With the help of policy and development, the background of Internet + Next, mobile Internet has great potential.
Android enterprise project development is to combine mobile communications and the Internet into one. It refers to the general term for activities that combine and practice Internet technology, platforms, business models and applications with mobile communication technology.
Android enterprise project development mainly studies basic knowledge and skills in mobile application software development and testing, and carries out mobile application software programming, testing, maintenance and sales. For example: development and testing of APP software such as Douyin, Meitu, weather, etc., functional design, interface design and test optimization of software, etc.
Android enterprise project development is also called mobile application development, or mobile Internet application development, mobile development, etc. It refers to the corresponding development work based on portable terminals such as mobile phones, PDAs, and UMPCs. Since these portable devices basically use wireless Internet access, it is also called wireless development in the industry. Mobile applications include the development of early WM handheld assistant devices, Web os devices, Java devices, Symbian devices, and now hot mobile applications such as Android and Apple devices. The formation of mobile applications has greatly expanded the functions of mobile devices. The device can not only rely on its own rudimentary functions, but can be expanded like a computer by installing applications, game programs, etc., making the mobile device a personal smart terminal that can better help people solve things. Android enterprise project development is a collection of processes and programs for writing software for small, wireless computing devices, such as smartphones or tablets. Android enterprise project development is similar to web application development and originated from more traditional software development. But the key difference is that mobile applications are typically written software that takes advantage of the unique capabilities offered by a specific mobile device. For example, use the iPhone's accelerator to write game applications.
With the vigorous promotion and popularization of smartphones, the scale of the mobile Internet market has been further expanded, and the number of users has continued to rise. As of March 2022, the number of mobile Internet users in China reached 897 million, an increase of 79.92 million from the end of 2020. The year-on-year growth rate of mobile Internet monthly active users declined. At the same time, my country's mobile Internet access traffic consumption reached 122 billion GB in 2021, an increase of 71.6% year-on-year in 2018; the average monthly traffic per household (DOU) reached 7.82GB/household/month, 1.69 times that of the previous year; short video applications It has become the main driving force for traffic growth. In 2019, mobile users used short video applications such as Douyin and Kuaishou to consume more than 30% of their traffic.
