title: custom android autofill for credit card expiration and second line of address
body: <p>I've been working on trying to utilize android oreo autofill service to populate the credit card expiration date and also the second line of the address. </p>
  
  <p>I'm trying to format the expiration date to essentially MM/YY and based off the link below, says to: <code>getAutofillType()</code> to return AUTOFILL_TYPE_DATE.
  <code>getAutofillValue()</code> to return a date autofillvalue.
  <code>autofill(AutofillValue)</code> to expect a data autofillvalue.
  See <code>setAutofillHints(String)</code> for more info about autofill hints.

  <p>The documentation below for autofill says to override autofill method, but i'm a little lost on where to start?Any help would be greatly appreciate. I'm also struggling with getting the second line of the address if anybody has insight on that as well?</p>
