Answer 1

I used this and it works!

WifiManager wm = (WifiManager) getSystemService(WIFI_SERVICE);
String ip = Formatter.formatIpAddress(wm.getConnectionInfo().getIpAddress());

Below permissions in the manifest file.

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

You can use this method to get the IP address of the device for IPv4 transfer and false for IPv6

 public static String getIPAddress(boolean useIPv4) {
    try {
        List<NetworkInterface> interfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
        for (NetworkInterface intf : interfaces) {
            List<InetAddress> addrs = Collections.list(intf.getInetAddresses());
            for (InetAddress addr : addrs) {
                if (!addr.isLoopbackAddress()) {
                    String sAddr = addr.getHostAddress();
                    //boolean isIPv4 = InetAddressUtils.isIPv4Address(sAddr);
                    boolean isIPv4 = sAddr.indexOf(':')<0;

                    if (useIPv4) {
                        if (isIPv4) 
                            return sAddr;
                    } else {
                        if (!isIPv4) {
                            int delim = sAddr.indexOf('%'); // drop ip6 zone suffix
                            return delim<0 ? sAddr.toUpperCase() : sAddr.substring(0, delim).toUpperCase();
                        }
                    }
                }
            }
        }
    } catch (Exception ex) { } // for now eat exceptions
    return "";
}
