I want to ask one question related to Android Development. I create registration and login activity with Sqlite DB. it works perfectly but it does not connect online.
Example:- In the android registration process, I created a username as PrimaryKey. I Register my self in one mobile username is a fighter and when I install that app in another android mobile and want to register an account with username fighter it accepts it or when I directly login with fighter message display that it is not registered.
