Android doesn't use normal URIs like:

file:///path_to_file

 Instead of that, in content providers you will have something like this:

content://com.example.app.provider/a_lot_of_data

This format can be different in Android activities which provide any files (FileDialog.fileUrl in QML) or only images (not implemented in Qt, I implemented it myself in my project, see PhotoDialog). That's why we need a build-in way to convert these URIs to normal paths, like a function:

QString QtAndroid::uriToRealPath(const QString &uri);

 
I have examples of implementation in my project:

• One
• Two
