Prompt image upload

[suhsin85]

How do you prompt for image upload from user of the app from the hard drive? Is such a function available on Toga?
I would like to make an app where it takes an image from either an iphone or an android, reads the metadata of the image, and gives feedback on the metadata.

Toga provides a file selection dialog; however, on mobile, this dialog isn't implemented because phones don't expose a traditional "filesystem" in the same way that a desktop machine does.

#1158 contains an old prototype version of this feature on Android; however, the objects you get back from this dialog aren't Python file objects - they're wrappers around Java's Storage Access Framework. A conceptually similar approach would be needed on iOS, but the implantation would be radically different.

#1171 is an open ticket for a cross-platform file API that would present a more traditional Python file API around the SAF, as well as other file wrappers.

Thank you. Do you know if there is any other Python module that would allow me to prompt photos/files upload from android and iOS?

Not really - iOS and Android support for Python is relatively new, so there's very few GUI libraries for wrapping those capabilities.
