Currently using the latest version 5.5.19 and when taking pictures on Android they are saving to the device gallery. I am using the option to prevent this (although by default it should be false anyway?). It looks like this was a known issue in the 5.5 release notes, i presume this is still the case?
I am picking this code up from a previous dev, but currently the callback copies the image (stored in rhodata/db/db-files folder by camera) to Rho::RhoApplication.get_base_app_path(), the image is then deleted from the original location. I'm not sure why it is moved, but this shouldn't effect another copy being in the gallery should it?
I am also getting mixed results with this. On a KitKat tablet I am getting the photo saved in the Pictures folder in the gallery. On a Marshmallow phone I am getting the photos saved to the Pictures and Camera folders in the gallery. On a Nougat tablet it is behaving correctly and not saving to the gallery at all.
