Preface
As we all know, Android is an operating system based on Linux. But for the Linux kernel, Android is just an application running on the kernel, and there is no difference from other applications running on the kernel.
Therefore, Android also needs a running environment, and the Linux kernel needs to load the resources needed for the Android Framework to run after the startup is complete. Only after the Framework is initialized can the corresponding APK application be started.
Framework is so important, how do we learn?
Regarding how to learn Android Framework development knowledge, I was fortunate enough to pick up this Android framework advanced development note in the hands of the former Alibaba technical director. Some of the knowledge chapters were published on Zhihu and even 1000+ likes. I will share it with you today.
This note explains the main modules of the Framework, from the deployment of the environment to the application of the technology, and then to the actual project. Let us not only learn the use of the framework technology, but also learn how to use the architecture to solve practical problems, from the shallower to the deeper, in detail Analyze Framework, let you learn this knowledge simply and efficiently!
I am an Android programmer, as an old Android who has been in a big factory and has many years of Android experience. Here, I have something to say.
Everyone knows that academic qualifications are a very useful stepping stone, but they are only a stepping stone, and academic qualifications do not represent everything.
Nowadays, many college students are not caring about their studies, absenteeism, skipping classes, and missed courses... these phenomena are not uncommon. It's not about which one. These phenomena exist in ordinary universities, as well as famous universities. It's just a matter of the proportion.
A prestigious university can only prove that you work harder than others in high school, are more able to withstand pressure, and are better than others in study plans and other aspects. Maybe you still have a certain talent in it-but this is only a stage Victory and short-term advantage.
Not all graduates from prestigious universities eventually become successful people, and not all graduates from ordinary schools are accomplishing nothing.
It is undeniable that during the school recruitment period, or just one or two years after graduation, a good degree has a great advantage among the same batch of job seekers. But the longer the time passes, the less the effect of the aura of education will be. On the contrary, those obscure doers will become the sought-after dark horses by virtue of their long-term persistence and hard work.
Finally, combined with the question of the subject: I am currently a sophomore in a general university, I don't want to go to graduate school, I want to work, I am afraid that I am not strong enough to find a good job. Very anxious.
In this case, there is nothing "very" anxious.
First of all, you don't want to take the postgraduate entrance examination, the academic qualifications are fixed "ordinary universities", this will not change, so why do you have to spend extra thoughts on "worrying" academic qualifications?
Secondly, you are only a sophomore, and your college career has not reached the end. There are many opportunities to increase your shining points and improve your competitiveness, and there are many places where you can learn, change, and work hard. Since academic qualifications cannot make a qualitative change, improve your abilities. To participate in the competition, to participate in the internship at Dachang
(Note: It’s worth mentioning here that going to a big factory for an internship is a very good way to work in a big factory. Generally speaking, they don’t have high educational requirements for interns. As long as you have the ability and can endure hardships, It’s not hopeless to join a big factory. As long as your performance during the internship period satisfies your leadership, you are hardworking, studious, and capable, you have a great chance to become a regular employee. Even if you can’t become a regular employee, you can go to another small company. Your “big factory experience” "It will also make you very competitive.)
You can also try to do self-media to cultivate your many abilities. (Nowadays, there are a lot of college students from the media, and there are many who make money from the media. You can try it, but this requires persistence, and there are few immediate results. However, many companies still value this, especially Tencent. Internet companies. Of course, you also have to look at your own majors, you can go to station B to see the growth history of those who are big UP owners from the media)
You can also participate in some training institutions to improve your professional skills. This point must be reminded: Although those educational institutions that advertise everywhere may not be unreliable, but those who have not heard of it, small institutions that have just been established must be careful.
At last
It is said that three years is a hurdle for programmers, whether they can be promoted or improve their core competitiveness, these few years are very critical.
With the rapid development of technology, from which aspects can we learn to reach the level of a senior engineer and finally advance to an Android architect/technical expert? I have summarized these 5 big pieces;
I have collected and sorted out the interview questions of Alibaba, Tencent, ByteDance, Huawei, Xiaomi and other companies in the past few years, and sorted out the requirements and technical points of the interview into a large and comprehensive "Android Architect" interview Xmind (in fact, it is better than Expect to spend a lot of effort), including knowledge context + branch details.
" Android Architecture Video + BAT Interview Special PDF + Study Notes "
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 don’t study it in depth, then it is difficult to achieve real technological improvement. I hope ** this systematic technical system ** can provide you with a reference for your direction.
F%95%E6%8B%BF%E9%AB%98%E8%96%AA%EF%BC%81.md)**I have a direction reference for everyone.
Although the road will be bumpy in 2021, everyone is saying that Android is going to decline, but don't panic, make your own plans, learn your own habits, competition is everywhere, and every industry is like this. Believe in yourself, there is nothing impossible, only unexpected. I wish you all the best in 2021.
