Как интегрировать Twilio в Android

Я пытаюсь запустить Twilio Android Quickstart, и я дошел до конца раздела "Исходящий звонок" на Java, но по какой-то причине. Я не добился успеха в Android.

Я также создал php Api для токена, но этот токен не дает мне кода возможностей. Этот api находится на нашем локальном сервере, то есть localhost.

Я также даю исходный код моего проекта.

public class MonkeyPhone implements Twilio.InitListener, DeviceListener,
    ConnectionListener {
private static final String TAG = "MonkeyPhone";
private Device device;
private Connection connection;
private final Context context;
private BasicConnectionListener basicConnectionListener;
private BasicDeviceListener basicDeviceListener;
private Connection pendingIncomingConnection;
InputMethodManager imm;
private boolean speakerEnabled;
private boolean muteEnabled;
static String capabilityToken;
public static final String ACCOUNT_SID = "XXXXXXXXXXXXXXXXXXXXXX";
public static final String AUTH_TOKEN = "XXXXXXXXXXXXXXXXXXXXXXX";

public interface BasicConnectionListener {
    public void onIncomingConnectionDisconnected();

    public void onConnectionConnecting();

    public void onConnectionConnected();

    public void onConnectionFailedConnecting(Exception error);

    public void onConnectionDisconnecting();

    public void onConnectionDisconnected();

    public void onConnectionFailed(Exception error);
}

 public interface BasicDeviceListener {
    public void onDeviceStartedListening();

    public void onDeviceStoppedListening(Exception error);
 }

public MonkeyPhone(Context context) {
    this.context = context;
    Twilio.initialize(context, this /* Twilio.InitListener */);
}

public void setListeners(BasicConnectionListener basicConnectionListener,
        BasicDeviceListener basicDeviceListener) {
    this.basicConnectionListener = basicConnectionListener;
    this.basicDeviceListener = basicDeviceListener;
}

/* Twilio.InitListener method */
@Override
public void onInitialized() {
    Log.d(TAG, "Twilio SDK is ready");
    try {
        // String capabilityToken =
        // HttpHelper.httpGet("http://------/mobile/auth.php");
         //capabilityToken = HttpHelper.httpGet("http:------/auth.php");
        capabilityToken = HttpHelper
                .httpGet("http://www.companyfoo.com/XXXXXXXXXXXXXXXXXXXXXXX");
        System.out.println(capabilityToken);
        device = Twilio
                .createDevice(capabilityToken, null /* DeviceListener */);
    } catch (Exception e) {
        Log.e(TAG,
                "Failed to obtain capability token: "
                        + e.getLocalizedMessage());
    }
}

}
@Override
public boolean receivePresenceEvents(Device arg0) {
    return false;
}
}

И php- код

 <?php

 require_once('Services/Twilio/Capability.php');
// Your API credentials from Account Dashboard here
$accountSid = 'ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$authToken = 'yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy';
$appSid = 'APzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz';

 $capability = new Services_Twilio_Capability($accountSid, $authToken);
 // give this app permissions
 $capability->allowClientOutgoing($appSid);
 // generate token that lasts for 5 minutes
 $token = $capability->generateToken(300);

  ?>'

Любая помощь будет принята с благодарностью.
