Describe the feature request
I am using AWS Mobile SDK and Cognito in an Android app.
The old AWS Mobile SDK which was de-supported offered a way to verify if there ia a signed in user: AWSMobileClient.getInstance().isSignedIn()
It also offered a method to get the signed in user: AuthenticationProvider.getLoggedInUsername()
The Amplify SDK for Android does not offer any method like the above that checks only the local user state.
I could, for example use Auth.getCurrentUser(), Auth.fetchAuthSession() or Auth.fetchUserAttributes() but all of these are going over the network.
There are usecases where it is important to check the local user state fast, for example if you wanted to display an entry in the app menu.
Consider the case of a new user that just downloaded an android app and opens the app for the first time.
The user never performed a sign in yet, and the user is on a slow network.
All methods offered by Amplify for checking if the user is signed in will go over the wire, because there is no local user state.
On a slow GSM connection, that could take several seconds.
Blocking the UI, waiting for the call to return would make for a bad user experience.
Can you offer a variant of that just checks the local state only?
