Hi, I love the premise of your app! Using the regular "Downloads" app on my phone requires me to unblock System in my firewall, so I've had to make a workaround in Termux. It would be really nice to have a trustworthy FOSS app to save files. Unfortunately I'm still running Android 7.0. Is there any chance of getting this to work on an older version than 9? I would be really grateful!

This seems like a real useful little tool – a pity it's only installable via Google's walled garden. Would you mind making it available for users without access to the Playstore? Like, tagging releases and attaching the APK there, or have your app built and listed by F-Droid?

I've made a fdroid build recipe for this Save on Device app since I find it really useful: https://gitlab.com/fdroid/fdroiddata/-/merge_requests/10077

Do you agree that we list it on f-droid.org?

As discussed in #1 – feel free to build on it (I'd suggest to e.g. add graphics like screenshots, icon, featureGraphic and maybe per-release changelogs) and to use my Fastlane cheat Cheat to guide you :wink:

I tried using this to save a photo from the vector camera app in f-droid. The photo is actually a .jpg but save on device tries to save it as a png and the file comes up 0 bytes.
