Question

In my Android mobile, I clicked from the phone and saw settings-> Wireless Controls->Wifi Settings and tapped on the network I have connected to. It popped up a Dialog with network status, level, speed, signal strength, IP address and security type. So just I got an IP address of network.

How can I get IP addresses of other wifi enabled devices by giving (known IP address got from my mobile) as a Input?

Actually to be clear, how to give specific known IP address as a Input and must be able to get other Unknown Ip addresses of Wifi enabled devices connected on the same network programmatically in Android 2.3 ?

Answer 1

For getting the IP Address you can check getIpAddress() in WifiInfo

Pseudo Code,

 WifiManager mWifiManager = (WifiManager) 
                                     getSystemService(Context.WIFI_SERVICE);
 WifiInfo mWifiInfo = mWifiManager.getConnectionInfo();
 Log.e("IP in Mask Integer", mWifiInfo.getIpAddress()+"");
 Log.e("IP Address", intToIP(mWifiInfo.getIpAddress())+"");

public String intToIP(int i) {
       return (( i & 0xFF)+ "."+((i >> 8 ) & 0xFF)+
                          "."+((i >> 16 ) & 0xFF)+"."+((i >> 24 ) & 0xFF));
}
