How can I recover a file that autosaved over a version on my tablet?

[Android Central Question]

I was writing a story and I closed my tablet but I didn't turn off my keyboard. Now the actual starting of the story is gone. I have been trying to find how to revert back to the version I want but none of them make scene. No, emailing it to myself won't work since it would be sending the wrong one. Please help.
