How to Convert Image url into Drawable Int

Question

Good Morning All !!!!

I am trying to display images in Imageview. But My requirement is ,i need to display images in Drawable Integer Format.I am getting data from Server and getting image in url format..

For ex :http://www.mymartmycart.com/images/detailed/3/4G_CONNECT_M1.jpeg

I want to convert this image in Drawable Format.

This is My code

This is my Interface

 public interface ECCardData<T> {

    @DrawableRes
    Integer getMainBackgroundResource();

    @DrawableRes
    Integer getHeadBackgroundResource();

    List<T> getListItems();
}

My Getter and Setter

     private Integer headBackgroundResource;

public Integer getHeadBackgroundResource() {
        return headBackgroundResource;
    }

    public void setHeadBackgroundResource(Integer headBackgroundResource) {
        this.headBackgroundResource = headBackgroundResource;
    }

This code where i set images

Integer drawableRes = dataset.get(position).getHeadBackgroundResource();
    if (drawableRes != null) {
        headView.setHeadImageBitmap(BitmapFactory.decodeResource(pagerContainer.getResources(), drawableRes, new BitmapFactoryOptions()));
    }

This is my parsing

 public static ArrayList<CardData> ParseCraft(String response) throws JSONException {


        ArrayList<CardData> alUser = new ArrayList<>();

        JSONObject jsonRoot = new JSONObject(response);

        JSONArray parentArray = jsonRoot.getJSONArray("products");

        for (int j = 0; j < parentArray.length(); j++) {

            JSONObject finalObject = parentArray.getJSONObject(j);

            CardData user = new CardData();

            user.setHeadTitle(finalObject.getString("product"));
            user.setPersonName(finalObject.getString("product_code"));

            JSONObject productJsonObject = finalObject.getJSONObject("main_pair");
            JSONObject productJsonObject1 = productJsonObject.getJSONObject("detailed");

            user.setHeadBackgroundResource(productJsonObject1.getString("image_path"));



            alUser.add(user);
        }

        return alUser;
    }

My json response

This code is working for me to convert Server image url into Bitmap

 String drawableRes="http://kartpay.biz/api/v1/file/banner/IHMOcSHU7yoTVOkwYi1bOOz8shrXXrJhayCPFO17.jpeg"
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
        try {
            URL url = new URL(drawableRes);
            headView.setHeadImageBitmap(BitmapFactory.decodeStream((InputStream)url.getContent()));
        } catch (IOException e) {
            //Log.e(TAG, e.getMessage());
        }

you can doing this work in background with coroutines :

    private fun loadImageFromWebUrl(url: String?) {
    lifecycleScope.launch(Dispatchers.IO) {
        val image  = try {
            val iStream = java.net.URL(url).content as InputStream
            Drawable.createFromStream(iStream, "src name")
        } catch (e: Exception) {
            null
        }

        image?.let {
            withContext(Dispatchers.Main){
                imageView.setImageDrawable = image 
            }
        }
    }
}
