SSH using SOCKS Proxy

Demonstrates how to connect to an SSH server through a SOCKS4 or SOCKS5 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);

    boolean success = false;

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

    CkSsh ssh = new CkSsh();

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to connecting:
    // The SOCKS hostname may be a domain name or 
    // IP address:
    ssh.put_SocksHostname("www.mysocksproxyserver.com");
    ssh.put_SocksPort(1080);
    ssh.put_SocksUsername("myProxyLogin");
    ssh.put_SocksPassword("myProxyPassword");

    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    ssh.put_SocksVersion(5);

    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.

    // Connect to an SSH server via a SOCKS proxy:
    String hostname;
    int port;

    // Hostname may be an IP address or hostname:
    hostname = "192.168.1.108";
    port = 22;

    success = ssh.Connect(hostname,port);
    if (success != true) {
        Log.i(TAG, ssh.lastErrorText());
        return;
        }

    // Your application is now connected to an SSH server 
    // through a SOCKS4 or SOCKS5 proxy. 
    // ..

      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
