title: How to save files on android storage, write to them, and access them later on?
body: <p>I am working on an android app to take float values from 3 different arrays, transform them into strings and then store them into a text file on the internal storage of the phone. I want to be able to access these values later and put them on a computer so I can do some statistical analysis on them. Can someone please show me how to do this?</p>
