Hot repair technology is a relatively advanced knowledge point in Android development, and it is a skill that intermediate developers must master when leading to advanced development. This article focuses on explaining the principles of thermal repair and thermal repair, the comparison of major thermal repair frameworks, and the practice of thermal repair functions in their own products.

Facing the impact of cross-platform technology, everyone knows the status quo of native developers. I believe that most of the interviewers have this experience, the requirements are getting higher and higher, and more and more technologies have to be learned and mastered!
So, what technologies do we need to learn to master? We might as well take a look at the current enterprise requirements for Android senior engineers.
This is the recruitment requirement of Chinasoft on Zhaopin.com. I framed the key points for everyone;
That is to say, if you want to be stable or develop well in the Android industry now, in addition to the previous Android development system, you must at least know the ones mentioned above.
In order to facilitate everyone to have a clear concept, I will send out these frameworks together.
1. Have a solid foundation of Java programming. The foundation is very important to a person's growth height. The cliché and image can be compared to the foundation of a tall building.
2. Familiar with mobile framework and tools to improve development efficiency
3. Proficient in APP overall performance tuning and code framework optimization
4. NDK module. Like the very popular artificial intelligence now
5. Mixed development and actual project combat. Cross-platform hybrid development apps are favored by enterprises because of their low development cost and the advantages of experience effect numbers, and hybrid development has become a general trend. Those who do not learn from actual combat operations are all on paper;
There are also some technologies such as front-end and WeChat applets that need to be added to the system. All the examples are not complicated.
to sum up
[Android detailed knowledge point mind map (skill tree)]
I personally do Android development. I have been doing Android development for more than ten years. I am currently working as a CTO and system architect in a startup company. Although Android is not as hot as in previous years, the era of finding high-paying jobs with four major components has passed. This can only show that the positions below the intermediate level of Android are saturated. Now senior engineers are still relatively lacking . Many senior positions give very high salaries (you may not be able to find a suitable one if you have more money), so I strive to become a senior engineer. is the most important.
Attached here are dozens of sets of ByteDance related to the above-mentioned interview questions, interview questions from JD.com, Xiaomi, Tencent, Toutiao, Ali, Meituan and other companies in 19 years. The technical points are organized into videos and PDFs (in fact, a lot of effort was spent than expected), including knowledge + many details.
Due to limited space, I will show you a small part in the form of pictures.
The detailed arrangement can be seen on GitHub;

There are a lot of materials for learning Android on the Internet, but if the knowledge learned is not structured, and when you encounter problems, you just taste it and stop studying it in depth, then it is difficult to achieve real technological improvement. I hope that this systematic technical system will provide you with a direction reference.
ID has a lot of information, but if the knowledge learned is not systematic, and when you encounter problems, you just taste it and don't study it in depth, then it is difficult to achieve real technical improvement. I hope that this systematic technical system will provide you with a direction reference.
Finally, I would like to give everyone a word and encourage each other!
