Refreshing ListView in Android after receipt of an SMS doesn't work

Question

I'm trying to refresh a ListView onReceive of a BroadcastReceiver. Within my main activitiy, which contains the ListView I'm talking about, I'm registering a receiver:

private final BroadcastReceiver smsIntentReceiver = new BroadcastReceiver() {
      @Override
      public void onReceive(Context context, Intent intent) {
        String mAction = intent.getAction();

        if(mAction.equals(INCOMING_SMS_ACTION)) {
            Log.v(runtimeVars.getMyName(), "reloading conversation list");
            curConversation = managedQuery(conversationURI, null, null, null, "date DESC");
            conversationAdapter = null;
            listConversations();
        }
    }
};

listConversations() looks like that

private void listConversations() {
    Uri smsURI;
    Uri personURI;
    Cursor curSms;
    Cursor curPerson;
    long personID;

    curConversation = managedQuery(conversationURI, null, null, null, "date DESC");
    conversationArrayList = new ArrayList<ConversationListObj>();
    this.conversationAdapter = new ConversationListAdapter(this, R.layout.conversationlist_item, conversationArrayList);
    setListAdapter(this.conversationAdapter);

    Log.v(runtimeVars.getMyName(), "listConversations");

    startManagingCursor(curConversation);
    for(curConversation.moveToFirst(); !curConversation.isAfterLast(); curConversation.moveToNext()) {
        smsURI = Uri.parse("content://sms/conversations/" + curConversation.getString(curConversation.getColumnIndexOrThrow("thread_id")).toString());
        curSms = managedQuery(smsURI, null, null, null, null);
        conversationArrayList = new ArrayList<ConversationListObj>();
        ConversationListObj newListObj = new ConversationListObj();

        newListObj.setThreadID(curConversation.getString(curConversation.getColumnIndexOrThrow("thread_id")).toString());
        if (curSms.moveToFirst()) {
            personURI = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(curSms.getString(curSms.getColumnIndex("address"))));
            curPerson = managedQuery(personURI, new String[] {ContactsContract.PhoneLookup.DISPLAY_NAME, ContactsContract.PhoneLookup._ID}, null, null, null);
            startManagingCursor(curPerson);

            if(curPerson.moveToFirst()) {
                personID = Long.parseLong(curPerson.getString(curPerson.getColumnIndex(ContactsContract.PhoneLookup._ID)));
                Bitmap contactPicture = generalMethods.loadContactPhoto(getContentResolver(), personID);
                if (contactPicture != null)
                    newListObj.setSenderPicture(contactPicture);
                else {      
                    InputStream input = this.getResources().openRawResource(R.drawable.person_dummy);
                    newListObj.setSenderPicture(BitmapFactory.decodeStream(input));
                }
                newListObj.setSenderName(curPerson.getString(curPerson.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME)));
            }
            else {
                newListObj.setSenderName(curSms.getString(curSms.getColumnIndex("address")));
            }
            newListObj.setMessagePart(curConversation.getString(curConversation.getColumnIndexOrThrow("snippet")).toString());
            conversationArrayList.add(newListObj);
            notifyConversationAdapter();
        }
    }
    curConversation.close();
}

Now, whenever I receive an SMS it seems as if my BroadcastReceiver was too fast. The new text message won't show up until I restart my app. So I basically think I made a design mistake, but how would it be correct? Looking at the logfile tells me

08-29 13:08:44.351: VERBOSE/SotapannaSMS(704): reloading conversation list
08-29 13:08:45.091: VERBOSE/SotapannaSMS(704): listConversations
08-29 13:08:45.921: VERBOSE/Telephony(171): getOrCreateThreadId uri: content://mms-sms/threadID?recipient=5556
08-29 13:08:46.081: INFO/NotificationService(59): enqueueToast pkg=info.SotapannaSMS.messaging callback=android.app.ITransientNotification$Stub$Proxy@43dbff88 duration=0
08-29 13:08:46.571: VERBOSE/Telephony(171): getOrCreateThreadId cursor cnt: 1

The new text message seems not to be within this conversation until I restart the app. I even tried to let my app sleep for 3 seconds to see if just waiting a bit would work, but that ended up in the same result.

What am I missing?
