onActivityResult's intent.getPath() doesn't give me the correct filename

Question

I am trying to fetch a file this way:

final Intent chooseFileIntent = new Intent(Intent.ACTION_GET_CONTENT);
    String[] mimetypes = {\"application/pdf\"};

To get the real name and to avoid getting a name that looks like "image: 4431" or even just a number, you can write code as recommended by CommonsWare.
The following is an example of a code that selects a single pdf file, prints its name and path to the log, and then sends the file by email using its uri.

private static final int FILEPICKER_RESULT_CODE = 1;
private static final int SEND_EMAIL_RESULT_CODE = 2;
private Uri fileUri;

private void chooseFile() {
    Intent fileChooser = new Intent(Intent.ACTION_GET_CONTENT);
    fileChooser.setType("application/pdf");
    startActivityForResult(Intent.createChooser(fileChooser, "Choose one pdf file"), FILEPICKER_RESULT_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == FILEPICKER_RESULT_CODE) {
        if (resultCode == RESULT_OK) {
            fileUri = data != null ? data.getData() : null;
            if (fileUri != null) {
                DocumentFile d = DocumentFile.fromSingleUri(this, fileUri);
                if (d != null) {
                    Log.d("TAG", "file name: " + d.getName());
                    Log.d("TAG", "file path: " + d.getUri().getPath());
                    sendEmail(fileUri);
                }
            }
        }
    }
}

private void sendEmail(Uri path) {
    String email = "example@gmail.com";
    Intent intent = new Intent(android.content.Intent.ACTION_SEND);
    intent.setType("application/octet-stream");
    intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "PDF file");
    String[] to = { email };
    intent.putExtra(Intent.EXTRA_EMAIL, to);
    intent.putExtra(Intent.EXTRA_TEXT, "This is the pdf file...");
    intent.putExtra(Intent.EXTRA_STREAM, path);
    startActivityForResult(Intent.createChooser(intent, "Send mail..."), SEND_EMAIL_RESULT_CODE);
}

hope it helps.
