Preface
Many Android developers often ask me, what should I learn to become a good Android engineer? For this problem, their descriptions are somewhat different, but, in general, we all need to learn a series of skills in order to become an excellent Android engineer.
In my opinion, such confusion is normal. Android is a huge and dynamic ecosystem. You may need to spend several weeks to understand and learn some of its related tools and concepts, but in the end you will find that many of them are not very important or not very useful. Therefore, in this article, I will share the important skills I used in Android development, hoping to help you and let you focus your energy on important things.
So, today, I will present an "Android Knowledge Graph", based on my own experience & what I have seen and heard, to tell you what you actually need to learn to learn Android, I hope you will like it.
For those who want to advance to become a senior Android developer, I think the first step is to build your own knowledge system , organize the knowledge points you have mastered and the in-depth knowledge points you need to understand, and then expand your knowledge, not Blind and directionless learning, follow the trend and learn what technology is ``fire'' or ``hot''. Now that the big front-end is very hot, they give up native learning and cross-platform. In fact, **cross-platform, flutter development positioning, Neither is to replace native, but to expand skills and capabilities in native development. **The advancement of learning is a step-by-step process, and I have enough stock in my mind, and I will be more comfortable with learning new technologies and architectures.
So the following shows which systems Android advanced learning should touch! (The knowledge and technical points summarized in the picture are the focus and difficulty of learning Android nowadays, and there will be actual projects as a reference, you can compare which part of the study of a topic content, because the picture is too large, only the branches shown below are detailed The branch will not be displayed. If you need a complete Xmind system diagram, you can privately mail me to receive it.)
1. Essential skills for architects
2. Android framework architecture
3.360° performance tuning in all aspects
4. NDK module development
5. Interpretation of open source framework by design thinking
6. Architects become actual combat
7. Other
For some of the technical points of the above-mentioned knowledge mind map, there are special explanation videos to share, with a complete version of the [ System Outline ], and multiple sets of [ Dachang Interview Questions Analysis ] carefully organized from the Internet and corresponding to the content , for everyone to free Download, hope to help some people who are on the way to advanced learning Android.
to sum up
Finally, in order to help everyone deeply understand the principles of Android-related knowledge points and interview-related knowledge, here are the 14 sets of real interview questions that I have collected and compiled by Tencent, ByteDance, Ali, Baidu and other 2020 interview questions . I have organized the technical points into Video and PDF (actually took a lot more effort than expected), including knowledge + many details.
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 do not research 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.
Direction reference.
