FileProvider.getUriForFile: check for authority used

Question

I am using a simple method to capture an Image from Camera but I get the error reported below at this point:

Uri photoURI = FileProvider.getUriForFile(ReceiptActivity.this, "com.example.ves.gennaio3.fileprovider", pictureFile);

According to me, it is related to the authority used, but it seems correct in the Manifest.

AndroidManifest.xml

<provider
 android:name="android.support.v4.content.FileProvider"
 android:authorities="com.example.ves.gennaio3.fileprovider"
 android:exported="false"
 android:grantUriPermissions="true"
 android:readPermission="com.company.app.fileprovider.READ">
 <meta-data
  android:name="android.support.FILE_PROVIDER_PATHS"
  android:resource="@xml/file_list" />
</provider>

res/xml/file_list.xml

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

Java

public void captureImage(View view) {
    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (cameraIntent.resolveActivity(getPackageManager()) != null) {
        pictureFile = Helper.getPictureFile(ReceiptActivity.this);
        if (pictureFile != null) {
            Uri photoURI = FileProvider.getUriForFile(ReceiptActivity.this, "com.example.ves.gennaio3.fileprovider", pictureFile); //error here
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
            startActivityForResult(cameraIntent, REQUEST_PICTURE_CAPTURE);
        }
    }
}

PS. I have tried to make a slim question but it looks like that my post is mostly code, so I am adding other unuseful text just to make it postable.
