While using broadcastreciver for checking sms status, it shows the toast when sms is sent but shows nothing when sms is not sent or delivered (im testing it by putting an abrupt number). the code im using is the one ive seen the most on every site of checking sms delivery status. But my code is only showing the status when sms is sent successfully. Can any one get a hint of what am i doing wrong ? I hav this method in doInBackground() and so obviously im using AsyncTask. Thanks guys

public void send_SMS(String list, String msg, AtaskClass task) { String SENT = "SMS_SENT"; String DELIVERED = "SMS_DELIVERED";

    SmsManager sms = SmsManager.getDefault();

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
        new Intent(SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
        new Intent(DELIVERED), 0);

    //---when the SMS has been sent---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context context, Intent arg1) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(context, "SMS sent", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE: Toast.makeText(context, "Generic failure", Toast.LENGTH_SHORT).show();
