Answer 1

Changed since 6.0 and later: 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.

Behavior Changes in 7.0:

Device owners can access device identifiers. A Device owner can access the Wi-Fi MAC address of a device, using DevicePolicyManagewr.getWifiMacAddress(). If Wi-Fi has never been enabled on the device, this method returns a value of null.

i can find mac in 6 Marshmallow but not 7N. – Molina

Modified my answer. Now it should be solved. Use DevicePolicyManager (yes, above is DevicePolicyManagewr with W). There is a typo in the docs. – Ailurophile

After one hour,I just solved the Problem.....

DeviceAdminReceiver admin = new DeviceAdminReceiver();
DevicePolicyManager devicepolicymanager = admin.getManager(getApplicationContext());
ComponentName name1 = admin.getWho(getApplicationContext());
if (devicepolicymanager.isAdminActive(name1)){
            String mac_address = devicepolicymanager.getWifiMacAddress(name1);
            Log.e("macAddress",""+mac_address);
}

Happy Coding....

If "isAdminActive" is false, what does this mean ? – Wilie

This solution is not working since isAdminActive is returning false – Cerecloth
