Answer 1

Call AccountManager.getAccountsByType(null) to retrieve all accounts, and check the returned account data includes the information you need. It may simply not be exposed.

Try calling AccountManager.blockingGetAuthToken instead. Also, make sure your manifest has the USE_CREDENTIALS permission set correctly.

You can see this discussion How to retrieve an Facebook-AuthToken from the accounts saved on Android

But I would also suggest Facebook SDK with offline access permission(This permission makes the access token returned by the OAuth endpoint long-lived, otherwise auth token is valid only for 1 hour.)
