Android Login - Best implementation

Question

I'm planning to implement an Android application that requires a login screen.

If the user opens the activity something like this should happen:

1. If user is logged in, goto 3
2. If user is not logged in open the login screen and perfom login
3. Show my application content

So, what's the "correct" way of implementing a login?

1. Implement a StartActivity that perfoms the check if the user is logged in, implement a LoginActivity that implements the logging and an ApplicationActivity that actually implements the application logics?
2. Implement just one Activity and handle the login by using multiple views which I show according to the application state?

Are there any examples or tutorials for this scenario?

Answer 1

I don't think that there is a "correct" way of doing this. Both solutions you describe seem fine to me, although I would merge StartActivity and LoginActivity into a single one.
