Raven Wallet “sign in”?

Howdy,

[NEWBIE ALERT] I've recently opened a Ravencoin Wallet via the Android App. That's where I keep all my precious ravens. Issue is I downloaded the Desktop version too, downloaded all past activity within the blockchain but obviously the balance in it is 0. I assume the software automatically generated a new wallet address for me? And if so, how do I tie the desktop wallet (sign in) to my actual Android wallet, where all my coins are? Thank you.
