Preface
Android developers who were already gearing up to work in large factories, this year is particularly difficult:
- The number of jobs waiting to be as high as 8.74 million! Intensified competition for talent!
- The epidemic has reduced the recruitment needs of most companies! Talent recruitment requirements are getting higher and higher!
Not to mention offer, now it’s hard to go out for odd jobs...

At last
The code really emphasizes quality and not weight. High-quality code is advocated by the current code industry. Of course, writing high-quality code definitely requires a fairly high level of professionalism, which needs to be gradually absorbed and mastered in daily code writing. Who is not learning every day, and the purpose is not to write high-quality code for a certain function.
Therefore, the Long March is still long, so let's be a pragmatic programmer.
Finally, the editor has a series of learning materials for Android to improve, and those who are interested can check it out~
