In my android device I am trying to find its IP address(IPV4).
If I do the following code
InetAddress inet = InetAddress.getLocalHost();
System.out.println(inet.getHostAddress()); //giving me 127.0.0.1
The code is giving me 127.0.0.1.
I wanted to get the actual IP 198.168.xx.xx.
(In My pc the same code giving me the actual IP though.)
public static String getIpAddress() {
try {
for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()&&inetAddress instanceof Inet4Address) {
String ipAddress=inetAddress.getHostAddress().toString();
Log.e("IP address",""+ipAddress);
return ipAddress;
}
}
}
} catch (SocketException ex) {
Log.e("Socket exception in GetIP Address of Utilities", ex.toString());
}
return null;
}
Give permissions
Also add in mainfest.
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
You can use this to get your IP address.
WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
int ipAddress = wifiManager.getConnectionInfo().getIpAddress();
return String.format("%d.%d.%d.%d", (ipAddress & 0xff), (ipAddress >> 8 & 0xff),
(ipAddress >> 16 & 0xff), (ipAddress >> 24 & 0xff));
This returns it as a String in the form "X.X.X.X"
The only permission you need in your manifest.xml
is
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
