I am trying to receive an MMS message in my program. Here is what's in my manifest: 

   <receiver android:name="com.webnation.text2email.receivers.MMSBroadcastReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="android.provider.Telephony.WAP_PUSH_RECEIVED" />

            <data android:mimeType="application/vnd.wap.mms-message" />
        </intent-filter>
    </receiver>

However, when I receive an MMS message, my broadcast receiver is never called when stepping through it in the debugger. I'm running Android 7.0 on a Galaxy 7 (API 24). Did they put a stop to receiving MMS message programmatically?

Here is my broadcast receiver. This all used to work. 

public class MMSBroadcastReceiver extends BroadcastReceiver {
  public void onReceive(Context context, Intent intent) {

    this.context = context;
    String action = intent.getAction();
    String type = intent.getType();
    int typeMessage = -1;
    byte[] pushData;
    GenericPdu pdu = null;

    if (action.equals(ACTION_MMS_RECEIVED) && type.equals(MMS_DATA_TYPE)) {
        Bundle bundle = intent.getExtras();
        Timber.d("bundle " + bundle);
        if (bundle != null) {
            pushData = intent.getByteArrayExtra("data");
            PduParser parser = new PduParser(pushData);
            pdu = parser.parse();
            PduHeaders headers = pdu.getPduHeaders();

            Timber.d("buffer " + pushData);
            String incomingNumber = new String(pushData);
            int indx = incomingNumber.indexOf("/TYPE"); // not used, parse the number in MMUtils.getAddress instead
            if (indx > 0 && (indx - 15) > 0) {
                int newIndx = indx - 15;
                incomingNumber = incomingNumber.substring(newIndx, indx);
                char[] characters = incomingNumber.toCharArray();
                int index = 0;
                for (int i=0;i<characters.length;i++) {
                    if (Character.isDigit(characters[i]) ){


                        index = i;
                        break;
                    }
                }
                //indx = incomingNumber.indexOf("+");
                if (index > 0) {
                    incomingNumber = incomingNumber.substring(index);
                    TelephonyManager tm = (TelephonyManager)context.getSystemService(context.getApplicationContext().TELEPHONY_SERVICE);
                    String countryCode = tm.getNetworkCountryIso().toUpperCase();
                    try {
                        String prefix = CountryToPhonePrefix.prefixFor(countryCode).replace("+", "");
                        int indexOfBaseNumber = incomingNumber.indexOf(prefix);
                        if (indexOfBaseNumber > -1) {

                            if (indexOfBaseNumber == 0) {
                                int lengthPrefix = prefix.length();
                                indexOfBaseNumber = indexOfBaseNumber + lengthPrefix;
                            }
                            incomingNumber = incomingNumber.substring(indexOfBaseNumber);
                        }

                    } catch (IllegalArgumentException ie) {
                        Timber.e(ie);
                    } catch (IndexOutOfBoundsException ie) {
                        Timber.e(ie);;
                    }
                    Timber.d("Mobile Number: " + incomingNumber);
                }
            }

            int transactionId = bundle.getInt("transactionId", -1);
            Timber.d("transactionId " + transactionId);

            int pduType = bundle.getInt("pduType", -1);
            Timber.d("pduType " + pduType);

            byte[] buffer2 = bundle.getByteArray("header");

            if (buffer2 != null) {
                String header = new String(buffer2);
                Timber.d("header " + header);
            }
            List<MMSMessage> textMessages = MMSUtils.getMessagesFrom(context, intent); //meat of onReceive()
            sendMessages(textMessages);



        } else {
            Timber.e("Invalid PUSH data");
        }

    }


}
}

EDIT: after adding the RECEIVE_WAP_PUSH permission, the app started to work in the debugger, correctly receiving and processing MMS messages. However, the app is not processing MMS messages when in debug mode.

I tried using the android.provider.Telephony.WAP_PUSH_DELIVER action in my receiver and someone pointed out this was incorrect if not the default app.

    Do you have the appropriate permissions? Have you requested runtime permission where applicable? From the docs, permissions are RECEIVE_MMS or RECEIVE_WAP_PUSH depending on type. – Gabe Sechan Feb 28 '18 at 21:54
  • `my broadcast receiver is never called` how do you know this? Maybe your very first `if` statement evaluated to `false`. Use a debugger and log messages. – Matt Clark Feb 28 '18 at 21:54
  • I know because I ran the debugger and set the break point to the first line of the onReceive. And this used to work. – Kristy Welsh Feb 28 '18 at 23:21
  • @GabeSechan - I think I didn't have the permission RECEIVE_WAP_PUSH. I added it and now it works. – Kristy Welsh Mar 01 '18 at 15:15
  • Take a look at the klinker library. https://github.com/klinker41/android-smsmms – Arya Mar 10 '18 at 05:40
  • After briefly working, this application is no longer working when not in debug mode. Break points are not being tripped when receiving MMS messages. – Kristy Welsh Apr 12 '18 at 19:30

    have you requested `android.permission.RECEIVE_MMS` permission in your manifest? If so has the permission being granted? You can check it in Settings -> Apps -> your app -> Permission – Sagar Apr 14 '18 at 04:29
  • This is **not a duplicate**, because it refers to the API 24, which way different than KitKat API 19. We should probably add these labels to old posts to prevent excessive duplicate taggings. – not2qubit Oct 04 '18 at 17:06
