Application data, how to do it?

[Tais]

Please tell me, I am interested in methods for obtaining data paths storage applications such as images, jnson.

I created the apk with buildozer, but the method that works in Windows 

_dir = dirname(__file__)

dir_img = _dir + 'data/img'

dir_json = _dir + '/data/json'

...doesn't work in Android.

In logs there is an error:

I/python  (11849): IOError: The folder '/data/json' doesn't exist!

main.py:

_dir = dirname(abspath(__file__))

dir_json = _dir + '/data/json'

logcat:

I/python  (20770): IOError: The folder '/data/data/org.test.apptest/files/app/data/json' doesn't exist!

the problem was solved in this way: the program itself creates the necessary folders and files.
