HTTP/HTTPS using SOCKS4 Proxy

See more HTTP Examples

Demonstrates how to use HTTP/HTTPS with a SOCKS4 proxy. Android™

// 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);

    // This example assumes the Chilkat HTTP API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkHttp http = new CkHttp();

    // Using a SOCKS4 proxy is just a matter of setting a few properties.
    // Once these properties are set, all other coding is the same as when
    // the connection is direct to the HTTP server.

    // Set the SocksVersion property = 4 for SOCKS4
    http.put_SocksVersion(4);

    // Set the SocksHostname to the SOCKS proxy domain name or IP address, 
    // which may be IPv4 (dotted notation) or IPv6.
    http.put_SocksHostname("192.168.1.100");

    // The port where the SOCKS4 proxy is listening.
    http.put_SocksPort(1080);

    // Now do whatever it is you need to do.  All communications will go through the proxy.
    String html = http.quickGetStr("https://www.baidu.com/");
    if (http.get_LastMethodSuccess() != true) {
        Log.i(TAG, http.lastErrorText());
        return;
        }

    Log.i(TAG, html);
    Log.i(TAG, "----");
    Log.i(TAG, "Success!");

  }

  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."
