MateusRodCosta/SaveLocally — reverse-engineered prompt

Build me a simple Android app called Save Locally. I want it to appear in the Android share menu so that when I share a file from another app, I can choose this app and save that file anywhere on my device using the normal system file picker. It should also work when opened directly, so a person can pick a file inside the app and save it locally that way too.

Keep the experience clean, lightweight, and privacy friendly, with no account, no cloud stuff, and no extra clutter. A straightforward main screen is enough, plus a simple file details screen so people can confirm what they are saving before choosing the destination. Make it feel polished and ready to ship as a real Android app, and keep localization in mind so it is easy to translate later. If you need to, look up current Android docs online and fill in the missing implementation details.
