Resolve a Hostname to an IP Address

See more Socket/SSL/TLS Examples

Demonstrates Socket.DnsLookup, which resolves a hostname and returns one numeric IP address.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    CkSocket socket = new CkSocket();

    //  Resolve a hostname to a numeric IP address, waiting up to 5 seconds.
    String ipAddress = socket.dnsLookup("example.com",5000);
    if (socket.get_LastMethodSuccess() == false) {
        Log.i(TAG, socket.lastErrorText());
        return;
        }

    Log.i(TAG, "Resolved IP address: " + ipAddress);

  }

  static {
      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
