Hi Bas,

downloading a huge amount of data with your mobile app can prove a bit troublesome. E.g. you might not want to rely on online connectivity too much for a mobile app, as bad internet connection then breaks functionality.

As for your question: We do not have a built in solution ready to check for free disk space. It is required to add custom Qt C++ code and do file system check with available Qt types.

Best,
Günther

hi Gunther,

i tried some code:

    QStorageInfo storage( m_writablePath );

    if (storage.isValid() && storage.isReady())
    {
        list << storage.name();
        list << storage.fileSystemType();
        list << QString::number( storage.bytesAvailable() );
        list << QString::number( storage.bytesTotal() );
    }

but it did not work on android.

and saw this:

https://bugreports.qt.io/browse/QTBUG-60215

 

 

will try something else.

i think i will call native functions on android to get proper info

Yes, seems the bug affects this use-case. If you prefer to add a custom solution by hand, you can use pre-processor macros as well, to use different code on another platform:

#if !defined(Q_OS_ANDROID)
// do this if not android
#else
// do this if android
#endif
