I am creating an android app in as3. I need a free online database to create a login system, where I can save the users username and password along with saved data of the user. I think the app will have a good number of users, so I need a database that works fast. I tried MAMP, but it creates local server, so I need to open the software to use the database from the app. But I need a database that I can access from anywhere, anytime.
How can I get a free online database for my android app?
