Answer 1

As Per Android 6.0 Changes:

https://developer.android.com/about/versions/marshmallow/android-6.0-changes.html#behavior-hardware-id

To provide users with greater data protection, starting in this release, Android removes programmatic access to the device's local hardware identifier for apps using the Wi-Fi and Bluetooth APIs. The WifiInfo.getMacAddress() and the BluetoothAdapter.getAddress() methods now return a constant value of 02:00:00:00:00:00.

To access the hardware identifiers of nearby external devices via Bluetooth and Wi-Fi scans, your app must now have the ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permissions.

Answer 2

According to Android document WifiInfo API , an Android app has to be a system app and get below 2 permissions:

• android.Manifest.permission.LOCAL_MAC_ADDRESS
• Manifest.permission.ACCESS_FINE_LOCATION

I tried on a rooted device of Android 10, it worked well.
