I'm getting pretty good at Android and I'm ready to take the next step towards my goal. I'm creating a social networkish social app that will require a user logins and connects to a database to pull user info.
I have been focused on the app side of things up until now. Where do I even start with something like this? what should I be studying?
I'm looking for keywords, tutorials, videos,the secret sauce to making a mobile service. What are the standards currently? what kind of databases are Foursquare and Pandora using?
As for the app side, you should look at java OAuth examples for authentication.
