Android Question Handling data question

You should look into learning more about SQLite databases @kn1ghtofdarknes.

That is nowhere near the only solution but it's the solution that I would suggest you use.

I assume that the data will be shared with all the players. Here you need a server. Cheap hosted solutions come with php & MySQL. I prefer php as a layer in front of the db for security reasons (user credentials, encryption, etc.)

The workflow I'm intending is for the user to choose which team they want to create a roster for and then build the roster with that team's options. The way a team is built is from very stringent rules, max 16 players and each position has a max (usually 1, 2, or 4). So the underlying mechanisms from team to team don't change, just the names of the positions, the maximum number of positions allowed and some other pieces of data about the player. I'll take a look at the SQL server idea, but I'm not very advanced and I'd prefer the least technically advanced, if slightly more work way of doing it to wrap my head around the process.
