Upstream issue: https://github.com/PolyMeilex/rfd/issues/82 - i don't know how feasible implementing this in rfd would be though.

As far as I know, Android Indent should be enough to pick files, though it is a bit complicated to use.

In addition, iOS UIDocumentBrowserViewController cannot get paths of picked files. Instead, it returns array of NSURL, and you get the content of the files with [NSData dataWithContentsOfURL:] or [NSInputStream inputStreamWithURL:]. It is different from the dialog API of tauri and rfd now.

RFD already has to handle this because web does not have paths either, that's why async file dialogs return FileHandle new type, instead of a path (could do the same for sync ones, but those are not supported on the web so there was no reason to do it so far), it is unwrappable on platforms that support paths tho. So I think it should be doable.

I've tried for both mobile platforms.

iOS: https://github.com/Berrysoft/file-picker-ios , which reads the file content and passes the Arc<[u8]> as FileHandle. It is a simple library and could be used anywhere.

Android: https://github.com/Berrysoft/file-picker-android , which copies the file to a reachable path and passes the PathBuf. It is a Tauri plugin.

I don't have much time to investigate how to integrate them into Tauri. Maybe there are someone would like to take my code as reference.
