Android test or interview questions

I have been recruiting Android Developers for the project team recently. In the interview process, it is also a process of self-improvement to understand the subject's project and ask questions.

As people have already been recruited, I have sorted out some of my favorite questions and made them into this test or interview question. I hope it will help you find a job. Roar ~~~
