Answer 1

Ref : Instant App - Digital Asset Links Protocol

This happened to me when I had generated an assetlinks.json file from my debug keys, rather than the release keys. It shows up as verified in Android Studio, then fails on the server. Double check that the signing config is correct for your asset links file, and that the fingerprint in the file matches the SHA256 fingerprint of your release key. You can get your release key's fingerprint by running

keytool -list -v -keystore ~/my_keystore.jks

Another cause can be if you've enabled Play signing. In that case, you have to use the fingerprint provided in your developer console, not the one for the key you signed the APK with locally (the local one is called your "upload key"). This isn't obvious in Android Studio at all, since its asset link file generator doesn't give you an option to put in a custom fingerprint.
