java
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
public class IPTool {
public static boolean isWifiConnected(Context context) {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
return (activeNetwork != null && activeNetwork.getType() == ConnectivityManager.TYPE_WIFI);
}
public static String obtainIP(Context context) {
if (isWifiConnected(context)) {
// Attempt to obtain IP address using DHCP
