public abstract class LogInCallback extends Object
The easiest way to use a LogInCallback is through an anonymous inner class. Override the
done function to specify what the callback should do after the login is complete.
The done function will be run in the UI thread, while the login happens in a
background thread. This ensures that the UI does not freeze while the save happens.
For example, this sample code logs in a user and calls a different function depending on whether the login succeeded or not.
ParseUser.logInInBackground("username", "password", new LogInCallback() {
public void done(ParseUser user, ParseException e) {
if (e == null && user != null) {
loginSuccessful();
} else if (user == null) {
usernameOrPasswordIsInvalid();
} else {
somethingWentWrong();
}
}
});
