Database Connection to Android App?

Hey guys!

I’ve been working on releasing a game now for a while. The part I had to program in java is nearly done and I will be so happy once I release the whole deal. My game is working with a specialized algorithm to adapt to the user’s skill level.
To make that work properly I need the game to grad the appropriate files out of a MySQL database. In order to get all that to work I decided to try something like Aiven for MySQL.

Has anyone had any experience with something like this altogether? Help would be really appreciated!
