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);
    }

We must use Application Context because the target is independent of the activity lifecycle and avoid anonymous object to avoid garbage collector.

not working

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.
