phonesSet.add(phoneNumber);
long threadId = Threads.getOrCreateThreadId(context, phonesSet); // get the thread-id of the specific conversation thread
Uri threadUri = ContentUris.withAppendedId(Threads.CONTENT_URI, threadId); // get the thread-uri

String[] projection = new String[]{MmsSms.TYPE_DISCRIMINATOR_COLUMN, BaseColumns._ID, Conversations.THREAD_ID,
                    Telephony.Sms.ADDRESS, Telephony.Sms.BODY, "sort_index", Telephony.Sms.DATE_SENT,
                    Telephony.Sms.READ, Telephony.Sms.TYPE, Telephony.Sms.STATUS, Telephony.Sms.LOCKED,
                    Telephony.Sms.ERROR_CODE, Telephony.Sms.SEEN};

Cursor cur = getContentResolver().query(threadUri, projection, null, null, null);
DatabaseUtils.dumpCursor(cur);
