foreword
As an Android engineer for 3-5 years, we often encounter these bottlenecks:
1. Narrow technical vision
Working in small software companies and outsourcing companies for a long time, the technical vision is too limited
2. It is difficult to increase salary.
The salary increase space for junior and intermediate Android positions is limited. Basically, if you want to get more than 15k, you will not be able to get something that does not know the source code layer.
3. There are few learning resources.
It is difficult to improve after getting started. I rely on the simple business projects I have come into contact with to practice those cv techniques repeatedly. Most of the technologies on blogs and books are abstract and scattered, which can be used for reference and guidance, but there is no way to copy them into your own
With this Android development core knowledge notes compiled by the Ali P7 master , all bottlenecks can be quickly broken.
The entire notes are organized according to the knowledge system of senior engineers. Compared with many fragmented contents on the Internet, this knowledge note is completely arranged according to the knowledge system of Android development, which is more systematic, from simple to complex, and easy to learn. It will not be very difficult.
It is said that programmers are eating youth food. This is indeed a bit true. I didn’t think so before, but as I grow older, the facts tell me that this is indeed the case. After 30, you will find that your body is different. In terms of indicators, the indicators have declined, and the physical strength and mentality are somewhat behind. This age is often very embarrassing. Compared with young programmers, the output is not as high as others, but the company still pays you a high salary. If there is no better performance, why should the company pay high wages? Therefore, these people have entered the so-called mid-life crisis. In order to help these friends successfully overcome the mid-life crisis, I roughly sorted out the following learning routes for improving technology .

New beginning
There is no shortcut to change your life. This road needs to be walked by yourself. Only by thinking deeply, constantly reflecting and summarizing, maintaining the enthusiasm for learning, and building a complete knowledge system step by step, is the ultimate way to win. It is also the mission that programmers should undertake.
