title: Save for autofill dialog not showing up
body: <p>I have an activity that shows username UI, after entering that and tapping on continue button shows the enter password UI. On entering password and tapping on login button finishes the current activity and launches a new activity. On my device I selected Google autofill service, so on finish of the 1st activity I want "save for autofill?" dialog to show up, but it isn't. I prepared my app by adding autofillHints and nothing else in my activity. Should I add anything for the dialog to pop up?</p>
