FileProvider - IllegalArgumentException: Failed to find configured root

I'm trying to take a picture with camera, but I'm getting the following error:

FATAL EXCEPTION: main
Process: com.example.marek.myapplication, PID: 6747
java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/Android/data/com.example.marek.myapplication/files/Pictures/JPEG_20170228_175633_470124220.jpg

AndroidManifest.xml:

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="com.example.marek.myapplication.fileprovider"
        android:enabled="true"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />
</provider>

Java:

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch (IOException ex) {
            Toast.makeText(getApplicationContext(), "Error while saving picture.", Toast.LENGTH_LONG).show();
        }
        // Continue only if the File was successfully created
        if (photoFile != null) {
            Uri photoURI = FileProvider.getUriForFile(this,
                    "com.example.marek.myapplication.fileprovider",
                    photoFile);
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
            startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
        }
    }

file_paths.xml

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

I was searching whole day about this error and trying to understand FileProvider, but I have no idea what this error message tries to tell me. If you want more info/code, write me in the comment.


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()

This may resolve everyones problem: All tags are added so you don't need to worry about folders path. Replace res/xml/file_paths.xml with:

<?xml version="1.0" encoding="utf-8"?>
<paths>
  <external-path
    name="external"
    path="." />
  <external-files-path
    name="external_files"
    path="." />
  <cache-path
    name="cache"
    path="." />
  <external-cache-path
    name="external_cache"
    path="." />
<files-path
    name="files"
    path="." />
</paths>

EDIT: 1st June 2021

We should use only specific path which we need. Try alternate path on your own and use which you needed.

Got similar problem after enabled flavors (dev, stage).

Before flavors my path resource looked like this:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
    name="my_images"
    path="Android/data/pl.myapp/files/Pictures" />
</paths>

After added android:authorities="${applicationId}.fileprovider" in Manifest appId was pl.myapp.dev or pl.myapp.stage depends on flavor and app started crashing. I removed full path and replaced it with dot and everything started working.

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

If you are using internal cache then use.

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