How to share files from any path using a FileProvider?

问题

My app allows the user to download some content and store it in the folder of his choice. I want to create a ContentProvider to share those files, but I don't know how to do that when the downloaded files are stored outside of the app default path.

I tried to decalre to following filePath:

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="." path="/" />
</paths>

but it just try to match shared file path with the root of the app default folder. Is there a way share files from the SD card for example ? If so how can I do it ?

Use <external-path> instead of <files-path>. The documentation for FileProvider has a bug; <external-path> maps to Environment.getExternalStorageDirectory().
