Could you add details about why this feature is needed? Thanks.

Hello,
here are my real case.

The App (is an Android Altimeter App) asks to the Camera App to take a photo, it loads the image file from private space, it prints the altitude and the location in overlay onto the image, then it write the image into the Media Gallery.
In all these operation we don't want to loose all the Exif attributes that the Camera App added to the original file, so we copy them to the new file.

At the moment we asks for all attributes that the image could have, one by one, and copy the ones that we find.
The list of attributes which we query for, has been found empirically testing several images taken with the most popular Camera Apps of different phone brands.

Iterating on all attributes would be more simple and efficient.

Thanks for the explanation. In that case, would an API that allows copying EXIF data from one image file to another suffice?

It could help but not ideal for me, because the two images live in different moments, the Exif attributes are loaded with the image and go with it until the image are then written later.
I think that attribute iteration is anyway a clean and useful interface that could cover other real cases

Thanks
