无法获得短信发送

Question

我正在使用此代码发送短信。此代码发送短信，但无法送达：

public class SMSSend {

    public static final String ACTION_SMS_SENT = "com.test.client.SMS_SENT";
    public static final String ACTION_SMS_DELIVERED = "com.test.client.SMS_DELIVERED";
    public Context context;
    void sendSMS(String number, String msg)
    {
        SmsManager sm = SmsManager.getDefault();
        ArrayList<String> parts = sm.divideMessage(msg);

        Intent iSent = new Intent(ACTION_SMS_SENT);
        PendingIntent piSent = PendingIntent.getBroadcast(context, 0, iSent, 0);
        Intent iDel = new Intent(ACTION_SMS_DELIVERED);
        iDel.putExtra("addressee", number);
        PendingIntent piDel = PendingIntent.getBroadcast(context, 0, iDel, 0);

        if (parts.size() == 1)
        {
            msg = parts.get(0);
            sm.sendTextMessage(number, null, msg, piSent, piDel);
        }
        else
        {
            ArrayList<PendingIntent> sentPis = new ArrayList<PendingIntent>();
            ArrayList<PendingIntent> delPis = new ArrayList<PendingIntent>();

            int ct = parts.size();
            for (int i = 0; i < ct; i++)
            {
                sentPis.add(i, piSent);
                delPis.add(i, piDel);
            }

            sm.sendMultipartTextMessage(number, null, parts, sentPis, delPis);
        }
    }
}

我使用此广播接收器进行传送，但它无法正常工作：

public class deliverReceiver  extends BroadcastReceiver
{

    public static final String ACTION_SMS_SENT = "com.test.client.SMS_SENT";
    public static final String ACTION_SMS_DELIVERED = "com.test.client.SMS_DELIVERED";

    @Override
    public void onReceive(Context context, Intent intent)
    {
        String action = intent.getAction();

        if (action.equals(ACTION_SMS_SENT))
        {
            switch (getResultCode())
            {
                case -1: //Activity.RESULT_OK
                    MyToast.Show(context,"sent");
                    break;

                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    break;

                case SmsManager.RESULT_ERROR_NULL_PDU:
                    break;

                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    break;

                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    break;

                default:

            }
        }
        else if (action.equals(ACTION_SMS_DELIVERED))
        {
            String number = intent.getStringExtra("addressee");
            switch (getResultCode())
            {
                case -1: //Activity.RESULT_OK
                   MyToast.Show(context,number);
                    break;

                case 0: //Activity.RESULT_CANCELED
                    MyToast.Show(context,number);
                    break;

                default:
            }
        }
    }
}

我在清单中设置了所有需要的权限，也注册了广播接收器类。
