First, why early tasteharmonyos?

On September 10, Huawei announced at the HDC 2020 Conference that HarmonyOS 2.0 is officially open source, and has entered the Open Atom Foundation source code address: openHarmony.gitee.com. There are 134 repositories in total.

As soon as it was released, there was a lot of discussion among developers at home and abroad. Zhihu also became a hot topic, and various discussions emerged in several Android groups I was in.

We can’t help wondering, is the spring finally here for Chinese operating systems?

Of course not. In my opinion, Android will continue to be the most used operating system in the world for at least the next five years, but in the future, it is not clear that in 10 years, if the national level of policy promotion, then the speed will increase even more.

In the future, we still don’t know who will be the mainstream, but as geeks, we can give this system a try. After all, for us Android developers, this is still a matter of our jobs, not what others say.

So, for this opportunity, I’d like to take you hand in hand with HarmonyOS.
