Android - smsManager.sendTextMessage

Question

In this following code message is a Message class array which contains 100+ phonenumbers and sms messages.

for(Message msg: message)  {
    String msgString = msg.getSMSText1() + " " + msg.getTransporterNo() + "\n" + msg.getSMSText2();
    smsManager.sendTextMessage(msg.getPhoneNo(), null, msgString, piSent, null);
}

And this code for receiving broadcast after sending a message:

PendingIntent piSent = PendingIntent.getBroadcast(this, 0, new Intent("SMS_SENT"), PendingIntent.FLAG_UPDATE_CURRENT);
BroadcastReceiver smsSentReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String result = "";
        switch(getResultCode()) {
            case Activity.RESULT_OK:
                result = "Transmission successful";
                break;
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                result = "Transmission failed";
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                result = "Radio off";
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                result = "No PDU defined";
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                result = "No service";
                break;
        }
        Toast.makeText(getApplicationContext(), result,
                Toast.LENGTH_SHORT).show();
    }
};
registerReceiver(smsSentReceiver, new IntentFilter("SMS_SENT"));

Is there a way to pass additional data during smsManager.sendTextMessage? I'd like to pass additional data like message_id, and phonenumber so that I can find out which message was success or not.

Answer 1

You can attach the necessary data as extras on the Intent object. For example:

Intent sentIntent = new Intent("SMS_SENT");
sentIntent.putExtra("message_id", id);
sentIntent.putExtra("phone_number", number);
PendingIntent piSent = PendingIntent.getBroadcast(this, 0, sentIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Then you can retrieve them from the Intent passed into the onReceive() method of your BroadcastReceiver :

int id = intent.getIntExtra("message_id", -1);
String number = intent.getStringExtra("phone_number");

Also, as David Wasser reminded me below, to ensure a new PendingIntent is issued each time through the loop, you'll need to provide each a unique request code - the second argument in the getBroadcast() call. If the message IDs are unique, you can use those. Otherwise, a loop counter should suffice.
