I have a very tricky question that nobody was able to answer it so far.
My app needs to create and save a JSON file in the external storage.
When I uninstall the app and install it again, I want to click a button that opens a file picker and pick the JSON file I have created before.
Is that possible?

Yes. Suggest you dig further on this as it’s a routine operation, not at all “very tricky” or unanswerable.

Not sure who you’re asking, and why they thought it tricky, but this is a fairly typical use case. See: https://developer.android.com/training/data-storage for saving to shared, persistent storage.

@Chris Lee My bad! Didn’t see your response before posting because I hadn’t had a stable internet connection for a few hours.
