blackberry-10 - 如何使用 C++ 从黑莓设备 10 读取短信列表

Question

你能告诉我如何在黑莓 10 中阅读短信（测试消息）收件箱。我使用了消息文件夹 api。在我的设备中有 6 条短信。但调试时显示为零。这是我的代码

void Testmesagges::inboxSmsTest(){
     fprintf(stderr,"*****in*******\n");
      qDebug() << "***************Thegtf  is************************* ";
              bb::pim::message::MessageService messageService;
               bb::pim::account::AccountService accountService;


            //Get the SMS/MMS account
            QList<Account> accountList = accountService.accounts(Service::Messages,"sms-mms");
             fprintf(stderr,"*****count*******\n");
             qDebug() << accountList.count();
             fprintf(stderr,"*****Length*******\n");
            qDebug() << accountList.length();
            AccountKey accountId;
            if(accountList.count()>0){
             accountId = accountList.first().id();
            qDebug() << "***************The  is************************* ";
                      fprintf(stderr,"*****ID*******\n");
                       qDebug() << accountId;



             QList<MessageFolder> folders = messageService.folders(accountId);
             fprintf(stderr,"*****size*******\n");
            qDebug() << folders.size();
             fprintf(stderr,"*****count*******\n");
            qDebug() << folders.count();
             fprintf(stderr,"*****length*******\n");
            qDebug() << folders.length();
            MessageFolder firstFolder = folders.at(0);
             qDebug() << firstFolder.isValid();
             qDebug() << firstFolder.name();
            }
}
