The Android development army is vast. After nearly ten years of development, Android technology optimization is changing with each passing day. Now Android 11.0 has been released, and the Android system performance has been very smooth, which can be completely comparable to iOS in experience.

However, in the hands of major manufacturers, changing the source code and customizing the system made the Android native system become a mixed bag, and then in the hands of different levels of development engineers, because the technical level is uneven, even if many mobile phones are running the software performance Very high, there is still a lag when opening the application.

In addition, as product content iterates, functions become more and more complex, and UI pages become more and more abundant, which also becomes an obstacle to smooth operation. In summary, the performance optimization of APP has become a comprehensive quality that developers should have, and it is also a guarantee for developers to complete high-quality application works.

To this end, I integrated the actual performance optimization of Android performance by companies such as Ali, Tencent, ByteDance, and Meituan into a PDF document. Due to the excessive content, I will introduce the actual part first, and then the theoretical part.

Interview preparation

Understand these, naturally not afraid of interviews
Interpret some of the issues that most programmers care about before the interview
If the interviewer asks you "Do you have any questions for me?", how should you answer?
How to answer when the interviewer asks you about your advantages/disadvantages (avoid minefields)?
This is how programmer resumes should be written
