What are some useful articles, literature, or just technical tools for debugging a mobile application on a real device?

Question

Python

The essence of the question is... I made the first mobile application EXTREMELY simple, no bells and whistles, only the Appodeal SDK was unfamiliar, I did it in Android Studio, everything compiles, it works correctly on the emulator (on various devices), and on a real device it gives something like " An error has occurred in the xxxxx application" How to track where and what is wrong? By what means, what to read about them? Please tell me, otherwise I’m stupid, I’ve earned a campaign) Thank you in advance.

Answer 1

That hours is a list, and you are trying to put it into the index of another list.

Answer 2

hours = ['hour%s' % i for i in np.arange(1, 11)]
here you get a list
X[hours] = ...
here you use it as an index
So X
is a dictionary A mutable list cannot work as a dictionary key

Answer 3

what's wrong with debugging on a real device directly in android studio?!
