I read about the new key attestation API in Android N and wanted to test it but I’m missing some classes.
The key attestation is described here: https://developer.android.com/preview/features/key-attestation.html
In the first code snipped a Attestation class is used which can’t be found with the targetAPI set to API 24.
Attestation hardwareKeyAttestation = new Attestation(attestationCert);
Do I miss here anything? Do I need proprietary libraries?
