I've made a small app from where user can send SMS to many users at the same time. I've done it like it is done i all tutorials and it's working fine. I create a SMSManager, divide a message and send it as a multipart:

ArrayList<String> msgArray=smsManager.divideMessage(msg);
smsManager.sendMultipartTextMessage(phoneNo, null, msgArray, null, null);

Everything works fine. The problem is if user wants to send more than 30 messages in a couple of minutes. In that case Android displays a warning: 

"{MyAppName} is sending to many messages. Do you want to allow sending messages?"

For each messages above 30 sent messages, I receive that warning. It gives me an option to allow or to deny. The problem is that even if I click 'allow', messages don't get sent.

Imagine a situation where user chooses 35 contacts and want to send a message to all of them. After he clicks send, 30 messages are sent and for other 5 that dialog is displayed where user is asked does he want to allow further sending.

Even if I click 'allow', message doesn't get sent and only 30 messages are sent. This way user gets an impression that all messages are sent but they are not. Those 5 messages are not sent even if he allowed app to send them.

Is there a workaround for this problem? I need some workaround to find out which messages are not sent and the way to send them.

Thank you.

You shouldn't set null on ArrayList sentIntents argument but add actual array of PendingIntent - you can use that to check if your message was sended correctly. Take a look at documentation.

Probably answer to this question also will be helpful.

  • Thank you but there is a problem that none of those error messages work for this case. Generic failure, no service, null pdu and radio off are not triggered when that alert dialog shows. – user4386126 Feb 06 '15 at 15:57
  • so the result you receive in BroadcastReceiver is Activity.RESULT_OK? – pstrag Feb 06 '15 at 16:04
  • For first 30 messages I receive Activity.RESULT_OK but for other ones I don't receive any result. I have a feeling Google has some hidden result code which they use only internally. – user4386126 Feb 06 '15 at 18:54
  • I'm not sure but I think you can in this case file android bug report because it looks like bug for me: https://source.android.com/source/report-bugs.html – pstrag Feb 12 '15 at 09:31
  • Hmmm...but wait, Activity.RESULT_OK for 30 messages is quite OK - you can inform user 5 other messages wasn't send and ask if he want to send it again. – pstrag Feb 12 '15 at 09:34
