FileProvider – IllegalArgumentException: Failed to find configured root

Question

Your file is stored under getExternalFilesDir(). That maps to <external-files-path>, not <files-path>. Also, your file path does not contain images/ in it, so the path attribute in your XML is invalid.

Replace res/xml/file_paths.xml with:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-files-path name="my_images" path="/" />
</paths>

UPDATE 2020 MAR 13

Provider path for a specific path as followings:

<files-path/> –> Context.getFilesDir()
<cache-path/> –> Context.getCacheDir()
<external-path/> –> Environment.getExternalStorageDirectory()
<external-files-path/> –> Context.getExternalFilesDir(String)
<external-cache-path/> –> Context.getExternalCacheDir()
<external-media-path/> –> Context.getExternalMediaDirs()
