I created a Widget which displays WiFi details. For the nexus phone only MAC address is not displaying. The code which I am using to display MAC is given below.
myWifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
myWifiInfo = myWifiManager.getConnectionInfo();
mMacIp = myWifiInfo.getMacAddress();
For every other mobile it is displaying correctly.
Is the wifi off? (You can't get a MAC address of a disabled wifi).
Have you added the appropriate permissions?

I'm not asking about how to create a WIFIConfiguration
that I want to connect to.
But I'm asking how to set my own Device SSID for my own phone?
private WifiManager obWifiManager;
obWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = obWifiManager.getConnectionInfo();
sendMessage(wifiInfo.getSSID());
The above code has no setter method.
Only getter method. Please help!
I then stumbled upon this article. it said the configuration file is located almost there for any linux OS. There is an SSID setting over there!
So i search on that location but found none!
Probably android put it in a different order / place. Any clue?
I am trying to find the name of the Wifi interface through a call to android.os.SystemProperties.get("wifi.interface").
On most devices I have used, it seems to work fine, but on Samsung Galaxy Tab 2 (Samsung GT-P5100) and Samsung Galaxy Note 2 (Samsung GT-P7100), I am getting an empty string in response. Can anyone help me understand what is wrong here, or how I can get the Wifi interface name more reliably? I have seen the option to go through all network interfaces, get their IP addresses and get the IP address of the device and match the two. Will try it, but are there any other options?
Get the IP address of the WiFi:
WifiManager wifiMgr = (WifiManager)
context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiMgr.getConnectionInfo();
int ip = wifiInfo.getIpAddress();
And then match it to the same IP from NetworkInterface.getNetworkInterfaces()
I think "wifi.interface" property is not set in JB of note 2.
This is set in other devices variants like S2 etc.,
This need to be set to "wlan0" in one of the device specific rc file.
I am getting MAC address of devices using wifi interface:
WifiManager wifiMan = (WifiManager) this.getSystemService(
Context.WIFI_SERVICE);
WifiInfo wifiInf = wifiMan.getConnectionInfo();
String macAddr = wifiInf.getMacAddress();
Is there any way for retrieve mac address without wifi interface?
Also confirm me Can we able to change MAc address of android devices?
Please confirm me android framework support these things or not?
A MAC address uniquely identifies a network adapter (e.g. WiFi or Bluetooth), so you'll have to access that adapter to retrieve it's MAC address. To get the MAC address of a bluetooth adapter you can use:
BluetoothAdapter btAdapter = BluetoothAdapter.getDefaultAdapter();
if (btAdapter != null) {
String mac = btAdapter.getAddress();
}
Note that this code requires the android.permission.BLUETOOTH permission and that your code to get the WiFi adapter's MAC requires the android.permission.ACCESS_WIFI_STATE permission. Also, both codes may not work when the adapter is turned off.
There is this post on MAC spoofing (returning a false MAC address) but spoofing can only be done on rooted phones. If you'll google you'll probably find more info on MAC spoofing.
I am writing a program about the communication between android device and PC.
Is there any way to get the MAC address of BLUETOOTH or WiFi of an android device, when the Bluetooth or WiFi is turned OFF?
If so, how?
this works for me with wifi on and off i not try the bluetooth
WifiManager wimanager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
String address = wimanager.getConnectionInfo().getMacAddress();
Log.d("TOKEN", address);
Yes, you can get MAC addresses even when Bluetooth / WiFi is OFF.
Getting bluetooth information is as easy as this:
BluetoothAdapter.getDefaultAdapter().getAddress(); // MAC address
BluetoothAdapter.getDefaultAdapter().isEnabled(); // true if ON
No need to use Context, yay!
And to complete the answer.. WiFi state:
final WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifiManager.getConnectionInfo().getMacAddress(); // MAC address
wifiManager.getWifiState() == WifiManager.WIFI_STATE_ENABLED; // true if ON
Can my Android app find the MAC address of the Wifi access point it is connected to?
The docs for android.net.wifi.WifiInfo getMacAddress() don't provide any details.
See http://developer.android.com/reference/android/net/wifi/WifiInfo.html#getMacAddress().
I'm assuming this is the Mac address of my phone. Can I find the Mac address of the access point?
getBSSID() of WifiInfo class will return MAC address of remote access point.
BSSID explained here.
The following method will return the MAC address of the access point, null if there is no network currently connected.
public String getMacId() {
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
return wifiInfo.getBSSID();
}
Check out the application "Network Info II" from the Android Market. It does show the MAC address, but I'm not sure if this is still the phone's MAC. It also shows the BSSID, which has the same format as a MAC address so perhaps is what you're looking for.
I'm fairly sure that getMacAddress(), is, as you suspected for the Local Device.
If you can get the IP of the router/gateway/accesspoint, then you might be able to use the code in this post: https://web.archive.org/web/20160308014312/http://www.flattermann.net/2011/02/android-howto-find-the-hardware-mac-address-of-a-remote-host/ to do your bidding. Good luck!
