Try this code

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;

import android.app.Activity;
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
import android.os.Bundle;
import android.widget.Toast;

import com.blundell.tut.R;

public class MainActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        checkAvailableConnection();
    }

    void checkAvailableConnection() {
        ConnectivityManager connMgr = (ConnectivityManager) this
                .getSystemService(Context.CONNECTIVITY_SERVICE);

        final android.net.NetworkInfo wifi = connMgr
                .getNetworkInfo(ConnectivityManager.TYPE_WIFI);

        final android.net.NetworkInfo mobile = connMgr
                .getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

        if (wifi.isAvailable()) {

            WifiManager myWifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
            WifiInfo myWifiInfo = myWifiManager.getConnectionInfo();
            int ipAddress = myWifiInfo.getIpAddress();
            System.out.println("WiFi address is "
                    + android.text.format.Formatter.formatIpAddress(ipAddress));

        } else if (mobile.isAvailable()) {

            GetLocalIpAddress();
            Toast.makeText(this, "3G Available", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(this, "No Network Available", Toast.LENGTH_LONG)
                    .show();
        }
    }

    private String GetLocalIpAddress() {
        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()) {
                        return inetAddress.getHostAddress().toString();
                    }
                }
            }
        } catch (SocketException ex) {
            return "ERROR Obtaining IP";
        }
        return "No IP Available";
    }
}
