foreword
I believe that since you have been in the Android development industry, there must be a lot of voices about Framework around you. I have also been passed by interviewers many times in this regard; this shows the importance of Framework among Android developers.
The importance of Framework
Personally, I think that when you raise the question of how to learn the Framework in depth, you already have the most basic conditions - the desire to explore and the thirst for knowledge.
Now that the IT industry is in a cold winter, it is not easy to stand firm in it; so many Android developers can only find another way, and job transfer has gradually become a new path; and Framework is exactly as A necessity at the Android framework level; it is essentially packaged and put into the App. If you don't understand its mechanism, you will not be able to learn it thoroughly.
Today, the dividend period of the domestic mobile Internet has passed, and Android development engineers have been hard to find at the beginning, and now hundreds of people compete for a job. It can be said that there is basically no place for junior and intermediate engineers.
If the market is not good, you can’t change anything. The most important thing for a technical person is to improve the technical level . When the technology is improved, high-paying jobs will naturally beckon to you.
How to learn Framework?
I have been engaged in Android development for 9 years, and I am well aware of the dangers of pirated and fragmented materials. Here I have also collected and sorted out the knowledge points and learning routes for Android Framework underlying development technology for everyone! And integrated it into a PDF document **"Android Framework Source Code Development Secret"**.
This document can not only consolidate the core technical points of the underlying principles, but also grasp the architecture design methodology that is difficult for ordinary developers to touch. Then you will have core competitiveness that is difficult for your peers to copy when you are at work, in a team, or during interviews. [Friends in need, scan the QR code below to receive ]
