AConstruction Plan for Android 4G Mobile Intelligent Interconnection Training Laboratory

1Background and Development Trends of the Android Industry

1.1 Android Industry Background

Today, in every link of the communication industry chain, there is the presence of Android. Android is an operating system that fully connects the entire communication industry chain. Mobile solution providers, integrators, operators, content providers, and users are all playing Android and are surprised by its explosive growth rate. Android now has over 500000 new Android devices enabled every day.
With the expansion of the Android platform, there has been a talent shortage for Android, and the future talent demand gap will reach millions. But for Android engineers who meet the requirements, the difficulty of enterprise recruitment can be imagined. According to media reports such as the Beijing News, Android engineers earn a monthly salary of 8000 yuan per year. Li Kaifu once advised students on Weibo to transfer to Android software development. We believe that in the coming years, Android development engineers will become one of the hottest positions.

1.2 Android Development Trends

According to June 2015 data from Zhiku.com, there are currently approximately 3882 Android technology related positions that are in high demand, with 2298 effective positions available within a month. The main hot job positions include Android development engineer, Android software engineer, Android application development engineer, system driver engineer, Android mobile game development, Android system software development, Android programmer, Android game application version management, human-computer interaction analysis engineer, Android middleware development engineer, etc.

2、 ConstructionARequirements and Talent Training Objectives for Android 4G Intelligent Mobile Internet Training Room

1. To enhance students' engineering practice, innovation awareness, and technological innovation ability, with the goal of cultivating talents in smartphone software application and sensing IoT required for national and local economic construction. Through practical teaching, the basic theories in textbooks are integrated with widely used professional and cutting-edge technologies, enabling students to complete simple engineering practices during their undergraduate education on campus, and cultivating and shaping high-quality talents who possess both general and specialized skills. Realize seamless connection between schools and corporate talents.

2. At present, some professional courses such as computer science, electronic information technology, software engineering, and communication mainly rely on course lectures. Under this teaching mode, students lack practical operational experience guarantee and lack the cultivation of teamwork quality. It is not only difficult to enhance their profound understanding and integration of relevant theories, but also difficult to stimulate the spirit of active innovation. Android mobile Internet of Things technology is a new comprehensive discipline with strong applicability, which needs to be experienced in practice. So it is necessary for universities to have their own practical teaching environment, which will enable students to better adapt to the working environment of enterprises when they graduate.

3. Android software applications and IoT applications are practical technologies that require a large number of practical steps to learn. Like our microcontroller course, it requires an experimental development platform to give them the opportunity to understand and be exposed to new knowledge and technology, activate the learning atmosphere, broaden students' horizons, stimulate and improve their learning enthusiasm, and enable them to better complete basic courses.

4. To improve employment rates, apply the knowledge learned to practical situations, enhance hands-on abilities and innovation awareness, truly master various skills required by enterprises, and lay a solid foundation for employment.

5. Complete talent selection and accumulation, enabling some students to have the ability and opportunity to participate in real project production before graduation. At the same time, it is also beneficial to improve the overall level of the teaching staff and provide more direct opportunities for teachers to develop research projects. On the basis of reaching a certain level of talent reserve, students are divided into several groups such as "development, marketing, management", etc., and through cooperation with the company, they can truly carry out project development.
