Unable to find working solution with Intent.ACTION_SEND_MULTIPLE for multiple images to be attached to an email

Question

So here's the situation - I'm developing an Unreal plugin with native android features. Intention for single image works perfectly, but now, when I'm trying to add multiple image attachments using ACTION_SEND_MULTIPLE it's not starting activity.

No errors, execution stops on .startActivity(), wrapping with try-catch doesn't return any exceptions, Unreal passes images array without any issue. I feel like it's not building intent properly, but after 2 days of searching and countless hours of trials and errors I feel like it's time to give up and seek for advise here :)

Here's the java part of the code I'm suspecting isn't working:

public static void sendEMail(Activity activity, String subject, String[] extraImagePaths,
                         String[] recipients, String[] cc, String[] bcc,
                         boolean withChooser, String chooserTitle) {
    Intent intent = createEMailIntent(subject, recipients, cc, bcc);
    ArrayList<Uri> paths = new ArrayList<Uri>();

    if (extraImagePaths.length > 0) {
        for (String extraImagePath : extraImagePaths) {
            File fileIn = new File(extraImagePath);
            Uri arrayPath = Uri.fromFile(fileIn);
            paths.add(arrayPath);
        }
    }

    intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, paths);

    try {
        launchShareIntent(activity, withChooser, chooserTitle, intent);
    } catch (Exception e) {
        Log.d("AndroidLOG:", e.getMessage());
    }
}

private static Intent createEMailIntent(String subject, String[] recipients, String[] cc, String[] bcc) {

    return new Intent(Intent.ACTION_SEND_MULTIPLE)
    .setData(Uri.parse("mailto:"))
    .setType("image/*")
    .putExtra(Intent.EXTRA_SUBJECT, subject)
    .putExtra(Intent.EXTRA_EMAIL, recipients)
    .putExtra(Intent.EXTRA_CC, cc)
    .putExtra(Intent.EXTRA_BCC, bcc);
}

private static void launchShareIntent(Activity activity, boolean withChooser, String chooserTitle, Intent intent) {
    if (withChooser) {
        Intent chooserIntent = Intent.createChooser(intent, chooserTitle);
        activity.startActivity(chooserIntent);
    } else {
        activity.startActivity(intent);
    }
}

tried removing all of the extras, except images, but that didn't solve the problem.

Help would be much appreciated!

After more digging through SO found similar post, changed .fromFile() to FileProvider and it worked like a charm.

Snippet:

for (String extraImagePath : extraImagePaths) {
            Uri arrayPath = FileProvider.getUriForFile(activity, getAuthority(activity), new File(extraImagePath));
            paths.add(arrayPath);
        }
