Android Question Where should data be stored?

[RMarra]

I've been writing my data to File.DirInternal (mainly because that's the only option that doesn't give me an error about permissions). I want to show the files in the FilePicker, but I get an error that says

Application needs you permission to access SD card

I've been reading and writing to DirInternal this whole time under the assumption that it was NOT the SD card. Am I doing something wrong, or is FilePicker (1.01) not the right choice?

Read on Runtime permissions

If you want to restrict a choice by File.DirInternal, you don't need to use FilePicker, ContentChooser etc.
Retrieve a list of files using File.ListFiles and make a form from ListView and Button.

I'm not understanding why the FilePicker is having permission issues when I'm reading and writing to that directory just fine.

What do you mean with FilePicker? There are all kinds of classes named FilePicker.
I guess that the one you are using tries to list File.DirRootExternal which requires a permission.

I tried the one at https://www.b4x.com/android/forum/threads/filepicker.69161

Is there a different class you would recommend?

Are you setting the root parameter to File.DirInternal?

Can you post the full error message (right click to copy)?

As I understand, ContentChooser and github's libraries use ACTION_GET_CONTENT
https://developer.android.com/reference/android/content/Intent.html#ACTION_GET_CONTENT

As I read, ACTION_GET_CONTEXT can't be limited by specified directory. Or I am wrong ?
