Android Question WiFi Direct: How to get the connecting device name?

If DeviceA is the group owner and is expecting connection from both DeviceB and DeviceC, how can DeviceA find out which device, B or C, is connected when the event Manager_ConnectionChanged () is raised?

I tried something similar to getting own device name, but the intent wasn't triggered. I think the following filter isn't correct; could someone show me how to fix it, please?
manifest entry:
AddReceiverText(WiFiDirectGetConnectingDeviceNameService, <intent-filter>
    <action android:name="android.net.wifi.p2p.CONNECTION_CHANGED_ACTION" /> 
</intent-filter>)

TIA

Below is an answer (although no one confirmed that it works) to a similar question at Stackoverflow:

When you receive the WIFI_P2P_CONNECTION_CHANGED_ACTION broadcast, if you are on API level 18 or higher, there is an extra in the intent, called EXTRA_WIFI_P2P_GROUP.

EXTRA_WIFI_P2P_GROUP

This returns a WifiP2pGroup on which you can call getClientList(). This gives you a collection of WifiP2pDevices. Once you have a WifiP2pDevice you can just get the field "deviceName".

Sorry, it didn't work; the intent wasn't triggered when an incoming connection was made. Test project is attached, so that others could check if I did anything wrong.

Carefully reading the answers helps a lot here. ;-)
Please try the attached, untested, update (1.06).

It adds an event named IntentReceived (Intent As Intent).

Handle this event and post the output of
