Finish() Method in Blockstack Android SDK

Hello everyone,
I want to use finish() method in my app ,which uses Blockstack SDK, to close the browser after Blockstack sign-in. However, when I use that method, my app redirects to the “Blockstack Account” activity that exists in example-multi-activities project in the SDK. I guess there is a function overloading on finish() method, but when I go to its implementation from Android Studio, it shows the one that is in Android libraries. So, what am I missing?
Thanks in advance.
