Example app inconsistent with documentation

Description

Hi there,

The documentation for AuthorizationService::dispose mentions that this method should be called on onPause as well.

I'm running into troubles with the service being disposed on AuthorizationService::performTokenRequest.

Comparing my code to the example app, I see that the LoginActivity class only calls dispose on onDestroy.

What is the correct way to utilize the library?
