Receive non-connected devices when my device is in pairing mode

I activate the binding mode with this code:

private void setWifiTetheringEnabled(boolean enable) { WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE); Method[] methods = wifiManager.getClass().getDeclaredMethods(); for (Method method : methods) { Log.e("teste", method.getName()); if (method.getName().equals("setWifiApEnabled")) { try { method.invoke(wifiManager, null, enable); } catch (Exception ex) { } break; } } }

and I get devices connected using this code (and reading information)

  br = new BufferedReader(new FileReader("/proc/net/arp"));

but in this file (/ proc / net / arp) there are only connected devices, I want to get information (Mac address) about the device that just checked my phone in pairing mode.

ntcfg execution of my return:

Call exec("netcfg") ;

 /** * Execute a command in a shell * * @param command * command to execute * @return the return of the command */ public String exec(String command) { String retour = ""; try { Runtime runtime = Runtime.getRuntime(); Process p = runtime.exec(command); java.io.BufferedReader standardIn = new java.io.BufferedReader( new java.io.InputStreamReader(p.getInputStream())); java.io.BufferedReader errorIn = new java.io.BufferedReader( new java.io.InputStreamReader(p.getErrorStream())); String line = ""; while ((line = standardIn.readLine()) != null) { retour += line + "\n"; } while ((line = errorIn.readLine()) != null) { retour += line + "\n"; } } catch (java.io.IOException e) { e.printStackTrace(); } return retour; }

It will execute the "netcfg" command in the shell and output as follows

 lo UP 127.0.0.1/8 0x00000049 00:00:00:00:00:00 sit0 DOWN 0.0.0.0/0 0x00000080 00:00:00:00:00:00 eth0 UP 0.0.0.0/0 0x00001003 78:c5:e5:a2:b2:d0 wlan0 DOWN 0.0.0.0/0 0x00001002 64:70:02:20:79:31

Includes connected network interfaces , status , IP obtained & MAC address .

The last field is for the MAC address. You must parse the MAC address from this separate line.
