I am using the Google SafetyNet API to detect device tampering in my application. Reference:: https://developers.google.com/android/reference/com/google/android/gms/safetynet/package-summary
But I cannot find any reference to the minimum support OS version. I thought I read somewhere that it was 7.0 but can't find that now.
It used to say "since" in the API docs, which was useful to tell the requirements but that seems to have disappeared.
What is the earliest version of Android that SafetyNet will work on, as supported by Android? Thanks.
