I am a bit of a newb myself, but so far none of the responses seem super-helpful.
You cannot currently use Shared Preferences to read the preferences in another package, the documentation says this is currently unsupported. If you combine the two apps into the one package, I think they can share Preferences. If separate apps, you should be able to load the Settings screen of app A from inside app B by sending an intent from app B to app A's settings screen. You may then also be able to do your login processing inside app A's setting screen, meaning that a login occurs within app A's settings before app "B" tries to access the server. As several people have pointed out, the correct way of passing information between apps is through a content provider, typically a database. However, Preferences are super easy to code up, and handle virtually all of the machinery. For a newb (such as myself and probably you), Preferences are more straightforward than Content Providers, and a solution based on Shared preferences is easier to implement if it can do what you want. That's my experience, anyway.
