Android global exception handling

When doing android project development, everyone knows that if the program makes a mistake, a forced exit pop-up box will pop up. This is no problem in itself, but this UI is really ugly, not to mention users can’t accept it, even ourselves. It may not be acceptable. Although we always go through careful testing when we release the program, we will inevitably encounter unexpected errors.

Today, I will customize the handling of a program error, similar to the crash of iphone. (Although the flashback is not what users want to see, it is obviously much better than the native pop-up in terms of user experience)

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 should the interviewer answer when you ask about your advantages/disadvantages (avoid minefields)?
This is how programmer resumes should be written

to sum up

Nowadays, new technologies are emerging in an endless stream. If we study in-depth every time a new technology is released, it is easy to distract our energy. It may take a long time for us to use the new technology in our work. When the new technology we learn cannot be applied to the application, it is easy to be forgotten by us. When we really need to use it in the end, we have to start from scratch (though it will Faster).

I think as a technical person, you should embrace the new technology. When you enter this industry, you should know that this is an industry that has lived and learned the old, so in the face of new technology, don’t resist, just embrace change. Up.

Flutter is obviously a brand new technology, and for this new technology at the beginning of its release, it takes a month to learn it, and the cost is indeed too high. But spend a day on the weekend to experience its development process and learn about its advantages and disadvantages, what it can or cannot do. This time is not unacceptable to us.

If you have time, actually reading through the Flutter documentation is the most comprehensive understanding of Flutter. But if we only have 8 hours, I hope to focus on some of the most noteworthy points.
