Question

我有一个用于Android系统的DESKTOP的可移植QT应用程序。在此应用程序中，我有一个按钮，用于打开某个文件夹，您可以在其中保存程序的备份。在台式机上可以完美运行，但是在Android系统上会出现错误。

Windows 64位系统，QT Creator 4.6.1，加密依赖项：boost_1_57_0，qrencode-4.0.2，openssl-1.0.2r，db-6.0.20，MiniUPnP，ifaddrs和apache-ant-1.9.4

void showBackups()
{
    boost::filesystem::path pathBackups = GetDataDir() / "backups";

    /* Open folder with default browser */
    if (boost::filesystem::exists(pathBackups))
        QDesktopServices::openUrl(QUrl::fromLocalFile(QString::fromStdString(pathBackups.string())));
}
