Android Question Read/Write Text Files

[PhilNewbie]

Hi,
I want to be able to read a json file at the start of my app and then periodically write to it back following user interactions. The initial version of the file has been created outside of the app.

While I've got it working using GetSafeDirDefaultExternal, I can't see where the file has been written to. I know that the file has been written because I can read it back in. I want to inspect the file manually to check that the contents are correctly formatted. Also, I will want to include this file with the app when it is installed.

Can someone enlighten me.

Regards
Phil

Put a Log to show the path, like this.
Log(rp.GetSafeDirDefaultExternal(""))
On my device I get this:
/storage/emulated/0/Android/data/b4a.example1/files
b4a.example1 is the Package name of the project.

I had already tried that and the result looks like yours. However, I can't find that location using file manager. I've tried tried adding a new folder like
Shared = RP.GetSafeDirDefaultExternal("app_files_dir") and then searching for that but nothing is found. However, the app appears to read and write the file within the folder OK.
It's a mystery

This folder is inaccessible to other apps in new versions of Android.

So if I have a file that I want accessible by other apps where do I place it and how do I access it in code within the B4X app?

Other apps aren't expected to directly access your app files. Android file system in new versions is mostly locked.

Your app can let the user choose the destination folder: [B4X] TextEditor - Save and load external files
Your app can also share files with other apps using FileProvider.
