java - Retrieving MAC Address Programatically - Android -


hey guys im having issue retrieving mac address of device programatically, before mentions other posts have read them such as: how find mac address of android device programmatically

however tried using code own application , tested simple log.d, find returning nothing. message of "seeing if works shows" nothing else. presuming mac address null.

log.d("seeing if works", macaddress2);

the code of have done shown here:

//set onclick listener mac address button         getmac.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view arg0) {                 wifimanager wifimanager = (wifimanager) getsystemservice(context.wifi_service);                 wifiinfo winfo = wifimanager.getconnectioninfo();                 string macaddress2 = winfo.getmacaddress();                  macaddress.settext(macaddress2);             }         });

which android version testing on? latest(10/2015) android m preview has blocked app getting hardware identifiers wifi , bluetooth.

to provide users greater data protection, starting in release, android removes programmatic access device’s local hardware identifier apps using wi-fi , bluetooth apis. wifiinfo.getmacaddress() , bluetoothadapter.getaddress() methods return constant value of 02:00:00:00:00:00.

there workaround reading wifi mac /sys/class/net/wlan0/address, blocked in android n claimed google.
