new DownloadImageFromUrlTask().execute(imagePath);

//add glide dependency in app gradle file
compile 'com.github.bumptech.glide:glide:3.7.0'

public class DownloadImageFromUrlTask extends AsyncTask {
        String downloadPath = "";

        @Override
        protected Bitmap doInBackground(String... args) {
            try {
                downloadPath = args[0];
                return BitmapFactory.decodeStream((InputStream) new URL(downloadPath).getContent());

            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }

        @Override
        protected void onPostExecute(Bitmap bitmap) {
            if (bitmap != null) {
                String photoFileName = downloadPath.substring(downloadPath.lastIndexOf('/') + 1);
                String root_Path =  Environment.getExternalStorageDirectory().toString();

                String saveImagePath = root_Path + "/" + photoFileName;

                saveBitmapToJPEGFile(MainActivity.this, bitmap, new File(saveImagePath), 900);
                loadImageWithGlide(MainActivity.this, myImageView, saveImagePath);
            } else {
                myImageView.setImageResource(R.drawable.default_photo);
            }
        }
    }

    public static Boolean saveBitmapToJPEGFile(Context ctx, Bitmap theTempBitmap, File theTargetFile, int i) {
        Boolean result = true;
        if (theTempBitmap != null) {
            FileOutputStream out = null;
            try {
                out = new FileOutputStream(theTargetFile);
                theTempBitmap.compress(Bitmap.CompressFormat.JPEG, CommonUtils.JPEG_COMPRESION_RATIO_DEFAULT, out);    //kdfsJpegCompressionRatio
            } catch (FileNotFoundException e) {
                result = false;
                e.printStackTrace();
            }
            if (out != null) {
                try {
                    out.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        } else {
            result = false;
        }
        return result;
    }

    public static void loadImageWithGlide(Context theCtx, ImageView theImageView, String theUrl) {
        Glide.with(theCtx)
                .load(theUrl)
                .diskCacheStrategy(DiskCacheStrategy.NONE)
                .skipMemoryCache(true)
                .into(theImageView);

    }
