Autofill Service for the sample app cannot be added as the autofill service on Android 12 or Android 13

On Android 12 and Android 13, the sample app cannot be added as the autofill service. On navigating to Settings -> Passwords & Accounts and then clicking on Google (which by the way is the way to change the Autofill Service), there is no Autofill Sample showing up as an option.

This results in the autofill sample not being of use as one cannot see any autofill in the app at all.

P.S. I have not tried < Android 12.

I actually figured this out myself. I had to apparently install a second APK for the Autofill Service in order for the sample services to show up.

1. Installation of 2 APK's should be mentioned explicitly in the Readme
2. The readme should update how instructions on how to change the autofill service provider -- from (Settings > System > Languages & Input > Advanced > Auto-fill service and select the sample app) TO (Settings -> Passwords & Accounts and then clicking on Google) at least for Android 12 and above
