title: What will I need in order to create an Android App that has users connecting with each other? (Registration & Log in)
body: <p>I want to build an app that allows users to register and then log in. I understand how to build the visual UI but I don't understand how I can get the code to work. I know I need to have a database that does authentication but how do I implement that with the Android SDK? Do I use MYSQL or some other database? Does anyone know any books that would help? Could someone please guide me? How about logging in with Facebook, how do I implement that? Any help would be greatly appreciated. Thank you!</p>
