Dynamic JSON parsing

I am a newbie to android. I am stuck at JSON parsing.
Following is my JSON, in this, the type of menu categories will be dynamic, and I want to arrange this JSON in sectioned recycler view.
Please help me out.
This is my JSON
{
"menu_items": {
"Plat": [{
"menu_name": "jambon à l'os",
"menu_cost": "18.00",
"menu_count": "1",
"category": "Plat",
"menu_tax": "5.50",
"code": "€"
},
{
"menu_name": "tacos",
"menu_cost": "6.00",
"menu_count": "1",
"category": "Plat",
"menu_tax": "5.50",
"code": "€"
}
],
"Entrée": [{
"menu_name": "avocat",
"menu_cost": "7.50",
"menu_count": "1",
"category": "Entrée",
"menu_tax": "5.50",
"code": "€"
}]
},
"order_data": {
"order_id": "278",
"order_number": "REF-5d5e6b86",
"created_at": "1566468998",
"instructions": "",
"fullname": "Rohan Chitnis",
"phonenumber": "7610771871",
"useraddress": "Brest, France",
"image_path": "https://restau-at-home.bzh/uploads/attachments/Jellyfish_2019_08_21_10_49_21.jpg",
"wp": "pune",
"code": "€",
"promocode": null,
"promo_value": null,
"promo_type": null
},
"order_details": {
"total_items": "3",
"order_total": "31.50"
},
"promo_applied": "0",
"error": {
"code": "13",
"status": "200",
"message": "Ok"
}
}

Check this out. Create a generic response class. Extend your classes from that class. To do this properly you can look at Java Generics and Inheritance topics if you are using Java. And then search about Sectioned RecyclerView in Android. Here is a library for this.

How to get Image URL based on name

My JSON contains only name of the food categories, Looks like below
[
{
"cu_id": "2",
"cuisine_type": "American"
},
{
"cu_id": "24",

I want to get default image automatically from Internet by searching 'cuisine_type', How to do that?

You can use pixabay api it's a free RESTful api for searching and retrieving free images and videos released on Pixabay under Creative Commons CC0.
Sending a GET request like this :
https://pixabay.com/api/?key={ KEY }&q=query&image_type=photo
where :
Key : the api key you get after creating an account
q : the queried object you need to look for
image_type : what kind of data you need (picture, video)
returned data will be something like this :
{
"total": 4692,
"totalHits": 500,
"hits": [
{
"id": 195893,
"pageURL": "https://pixabay.com/en/blossom-bloom-flower-yellow-close-195893/",
"type": "photo",
"tags": "blossom, bloom, flower",
"previewURL": "https://static.pixabay.com/photo/2013/10/15/09/12/flower-195893_150.jpg"
"previewWidth": 150,
"previewHeight": 84,
"webformatURL": "https://pixabay.com/get/35bbf209db8dc9f2fa36746403097ae226b796b9e13e39d2_640.jpg",

Well, it is true that you cannot find any url in the json output. The only thing that you can get from here is the videoId.
You can use this videoId as part of this https://www.youtube.com/watch?v="insert_videoId" to get a video link.
So in your case, this is the link https://www.youtube.com/watch?v=VGDqZjALH_M
