How to save Android application data to an externally accessible folder?

Question

Android

I have no programming experience in general and on android in particular, but I am forced to write a small application on it. It was written and tested on a tablet using the Google and copy-paste method, with the only exception - I need the application data (the essence of the questionnaire) to be saved in a file that can be easily extracted when connected to a computer. I was able to save the data to the internal (and, as I understand it, closed) application memory. Read too. But I broke my brain about Google when I tried to save my file to some open folder, like Download. Prompt, please, council, an example or the direction where to dig.

Answer 1

Permission in manifest to read data, and write file to internal memory.
