Multipart in Receiver SMS

Question

I have developed a program to send normal and encrypted SMS where I am trying to send long messages, more than 160 characters but; in the Receiver it is not receiving it right.

This is the logic of a normal message (short msgs <= 160 characters and long msgs > 160 characters).

builder.setNegativeButton("Normal", new DialogInterface.OnClickListener() {
    largoMsg = sendingMsg.length();
    int position = 0;
    for (int j = 0; j < ctdmsg; j++) {
        if (largoMsg > 160) {
            mensaje = sendingMsg.substring(position, (j + 1) * 160);
            position = (j + 1) * 160;
            largoMsg = largoMsg - 160;
        } else {
           mensaje = sendingMsg.substring(position);
        }
        SendSMS(mensaje);
    }
    dialog.cancel();
});

And this is the Receive part:

public void onReceive(Context context, Intent intent) {
     if (intent.getAction().equals(MySMSMonitor.SMS_RECEIVED_ACTION)) {
        Bundle extras = intent.getExtras();
        SmsMessage[] messages = null;
        infoSender = "";
        infoSMS = "";
        String phoneSender = "";
        if (extras != null) {
           // Retrieve the sms message received
           Object[] pdus = (Object[]) extras.get("pdus");
           messages = new SmsMessage[pdus.length];
           for (int i = 0; i < pdus.length; i++) {
              messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
              phoneSender = messages[0].getOriginatingAddress();
              phoneSender = PhoneNumberUtils.formatNumber(phoneSender, "JM");
              infoSender += messages[i].getOriginatingAddress();
              if (messages.length > 1)
                  infoSender = phoneSender;
              infoSMS += messages[i].getMessageBody().toString();
              creaDataReceiver();
           }
           MsgToats("!SMS recibido !!!");
           retrieveMensajes();
           refreshDisplay();
           Bundle bolsa = new Bundle();
           bolsa.putString("TLF", miTelefono);
           bolsa.putString("DUMMY", dummy);
           bolsa.putString("ADDRESS", infoSender);
           Intent intentnotify = new Intent(CipherActivity.this, NotificacionSms.class);
           intentnotify.putExtras(bolsa);
           startActivity(intentnotify);
        }
     }
  }

And this is the image of the one who receives

Short messages work fine for me with multiple destinations but; I can't get long messages to be well received.

Please I need help
