I am getting the data from the server. Then the data will pass to the adapter but it's showing me null.
Here is the error part:
Why I get the data is null?
What is the problem I am getting here?
Please help. Below I attach my Adapter Code and Activity Code.
Here is my Adapter Code:

I found the actual problem. The problem is here
model_items.setImage(s1.getString("image"));
model_items.setShop_name(s1.getString("shop_name"));
In this line, you can try to get an image from s1 object but in s1 has no field of image. That's why it throws an exception.
Remove this line and try again.
