SaveFile on Android ignores customized file name

[Gnietschow]

Awesome package! I'm currently exploring its capabilities for my project and stumbled upon a problem. I'm calling

FileToSave file = new FileToSave(srcPath, newFilename); NativeFileSO.shared.SaveFile(file);

to share a file under a new name on Android. This will call finally

public void SaveFile(FileToSave file) { JavaNativeSO.CallStatic("SaveFile", Activity, file.SrcPath, file.MimeType); }

in the NativeFileSOAndroid.cs, where it seems that the set newFilename is not passed to the share intent in the native code. Is this a bug or is it not possible to change the filename to share as a platform limitation?

Hi!
Yes, the mobile platforms (both Android and iOS) don't support changing the file name before saving out of the box. It definitely looks like I forgot to document that, so I'll keep this issue open until the next time I have time to work on this so I remember to add it for the next update.

If the plugin were to do it, it would have to copy the entire file to a temporary location with the new name first and then delete it once the file sharing is done. In my opinion that's too much for this plugin to just quietly do behind your back, both in terms of the performance overhead and the failure potential in case the user doesn't have enough storage space left. I think leaving this up to the application is best. In most cases the application can probably just rename the original source file without having to make a copy at all.
