Save image from network to external storage using Glide

OnButtonClick.java

 #Step 1
 Glide.with(mContext)
    .load(images.get(position).getThumbnail())
    .asBitmap()
    .into(new SimpleTarget<Bitmap>(100,100) {
        @Override
        public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {
            saveImage(resource,position);
        }
    });
 
 #Step 2
    private String saveImage(Bitmap image, int position) {
        String savedImagePath = null;

        String imageFileName = "JPEG_" + images.get(position).getName() + ".jpg";
        File storageDir = new File(
                Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
                        + "/Comicoid");
        boolean success = true;
        if (!storageDir.exists()) {
            success = storageDir.mkdirs();
        }
        if (success) {
            File imageFile = new File(storageDir, imageFileName);
            savedImagePath = imageFile.getAbsolutePath();
            try {
                OutputStream fOut = new FileOutputStream(imageFile);
                image.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
                fOut.close();
            } catch (Exception e) {
                e.printStackTrace();
            }

            // Add the image to the system gallery
            galleryAddPic(savedImagePath);
        }
        return savedImagePath;
    }

 #Step 3
    private void galleryAddPic(String imagePath) {
        Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
        File f = new File(imagePath);
        Uri contentUri = Uri.fromFile(f);
        mediaScanIntent.setData(contentUri);
        mContext.sendBroadcast(mediaScanIntent);
    }

Works well for me.
What AbuBallan said is true.
But the application get laggy and I get this when running it.

I/Choreographer: Skipped 296 frames! The application may be doing too much work on its main thread.

Do I need to load this code from AsyncTask or something?

getExternalStoragePublicDirectory is deprecated on Android Q

As a side note, placing .asBitmap() after .load(...) resulted in an error for me.
This error disappeared when I reversed the order.

Here's a StackOverflow question that addresses the issue I was facing.
