Preface
Since the advent of Hongmeng, there has been no end to talk about cheating Android.
But for those who are still saying that Hongmeng is a rip-off of Android, do you know that Microsoft has set up a dedicatedstrategic team To deal with Hongmeng, these professionals have already known that Hongmeng will be a huge threat to Windows. As a giant company that has monopolized the operating system for many years, Microsoft can theoretically take a year-long holiday without any impact. They make money, but the emergence of Hongmeng is the first time they have felt a crisis in more than 20 years.
Penetration rate of Windows operating system in China
Microsoft's Windows operating system occupies an absolute market share worldwide and has become synonymous with the personal computer field. However, in the Chinese market, Windows' market share far exceeds that of other countries, which is related to the strategy adopted by Bill Gates.
In the early 2000s, domestic operating systems such as openthos and Deepin came out one after another and gained certain market recognition.
However, the competition among the heroes not only failed to develop a domestic operating system, but also allowed Microsoft to take advantage of it. Its connivance towards piracy and its rich software ecosystem caused all Chinese users to rush to embrace the WINDOWS operating system. The domestic operating system that made Zhongcong lose the soil for survival.
This strong development of Microsoft has led to the difficult development process of China's local operating systems. Although Chinese operating system manufacturers have been working hard for decades, Windows' monopoly has kept them marginalized.
Some time ago, I saw a technology blogger publish information about the successful adaptation of the PC version of Hongmeng operating system, which gave people hope that the Hongmeng PC version may become the rise of domestic PC operating systems.
The successful adaptation of Hongmeng PC brings hope to domestic operating systems. First of all, Hongmeng OS is a cross-device distributed operating system. It has hundreds of millions of users and can be seamlessly switched on various devices. , has been recognized by many users.
And after several years of hard work, everyone also knows that no matter how good foreign software is, there is still a risk of supply interruption at any time. The emergence of Hongmeng has brought us hope, and with the introduction of national policies to support Hongmeng, it will definitely be able to take the lead. At the forefront of the world.
This is also an opportunity and an opportunity for programmers. An opportunity to grow with Hongmeng.
How to learn Hongmeng
The best time to plant a tree was ten years ago, followed by now. Considering that there are no systematic introductory materials on the market, I compiled a "Hongmeng Zero Basics Beginner's Study Guide", hoping to help those who want to learn Hongmeng, but is there anyone in the direction who can provide a little help? This document is suitable for beginners in HarmonyOS application development (due to the excessive content of the document, in order to avoid affecting everyone’s reading experience, only part of the content is shown in screenshots. There is a free way to obtain the detailed full version at the end of the article!)

It inherits all the features of TS and is a superset of TS. Therefore, before learning the ArkTS language, it is recommended that developers have TS language development capabilities.
