I am using the following code:

WifiManager wifiMgr = (WifiManager) app.getSystemService(Context.WIFI_SERVICE);
return wifiMgr.getConnectionInfo().getMacAddress();

Problem is, the WIFI must be ENABLED in the device in order for me to read its address.
How can I still read the MAC of the WIFI even if the WIFI is off?

    You can’t. Depending on the device, if the wifi adapter is disabled then it may actually be electronically switched off, so you can’t read any info from it.

    From the Android Developers Blog:

    Mac Address

    It may be possible to retrieve a Mac address from a
    device’s WiFi or Bluetooth hardware. We do not recommend using this as
    a unique identifier. To start with, not all devices have WiFi. Also,
    if the WiFi is not turned on, the hardware may not report the Mac
    address.
