Android 7.0 introduced this feature: Key Attestation, which
gives you more confidence that the keys you use in your app are stored in a device's hardware-backed keystore.
but not perfect since
only a small number of devices running Android 7.0 (API level 24) support hardware-level key attestation; all other devices running Android 7.0 use software-level key attestation instead.
As far as I know this feature will be mandatory for devices shipped , not updated with Android 8.0
