SOLVED:
accountManager.invalidateAuthToken(account.type, null); doesn't seem to be
enough.
One has to provide the name of the old token instead of null.
Although the documentation says that the token can be null and it will
invalidate it for the whole account type.
Here is what works:
*try*{
calendarList = CalendarService.calendarList().list().execute();
accountManager.invalidateAuthToken(account.type, myToken);
}*catch* (Exception e) {
e.printStackTrace();
}
