Why I get this fatal error when I try to open the camera?

Question

In my Android Studio code, I am trying with the captureImage method to open the camera (below the code). When this method is called, I get a FATAL EXCEPTION (below the details). Reading the error, it seems that it was looking for a certain /storage/emulated/0/Android/data/com.example.ves.gennaio3/files/Pictures/OCR_201903162231401331084905.jpg that I am not calling anywhere. How can this be possible? How can I fix this issue?

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);
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
            startActivityForResult(cameraIntent, REQUEST_PICTURE_CAPTURE);
        }
    }
}

Your problem lies in your `FileProvider` configuration. Your `` element in the manifest for `FileProvider` should have a `` child element, which in turn points to an XML resource configuring `FileProvider`. If you edit your question and post that XML resource, we can point out the specific problem. — CommonsWare, Mar 16 '19 at 21:52

@CommonsWare thank you. I have added the info that you asked. Tell me if they are not enough. — Stefano, Mar 24 '19 at 16:24
@denis_lor thank you but I have already read those links and they are not effective for my situation. — Stefano, Mar 24 '19 at 16:25

<external-files-path name="my_images" path="my_images" />

This says that you want to serve up files that are located in a my_images/ subdirectory under the location returned by getExternalFilesDir(null).

The path that you are using is:

/storage/emulated/0/Android/data/com.example.ves.gennaio3/files/Pictures/OCR_201903162231401331084905.jpg

That is for a Pictures/ subdirectory under the location returned by getExternalFilesDir(null). Since my_images does not match Pictures, FileProvider does not know how to serve that file.

Either:

Change your file path to use my_images instead of Pictures, or
Change your <external-files-path> to have path="Pictures" instead of path="my_images"

Why I get this fatal error when I try to open the camera?
