                String id = mProducts.getSingleProductId.get(position);
                String name = mProducts.getSingleProductName.get(position);
                String price = mProducts.getSingleProductPrice.get(position);
                String oldPrice = mProducts.getSingleProductOldPrice.get(position);
                String discount = mProducts.getSingleProductDiscount.get(position);
                String description = mProducts.getSingleProductDescription.get(position);

because, your arraylist dont have item you are trying to click — Divyesh Patel, Dec 01 '16 at 07:15
Products mProducts = new Products(); @Diveyesh , i am accessing item from another class — Dinesh_Yogi, Dec 01 '16 at 07:18
error shows that your arrylist has no items and you try to access first item from it — Divyesh Patel, Dec 01 '16 at 07:20

The only thing that comes into my mind is that you get your mProducts asynchronously, so during debug it's enough time to receive data, but during run mode it's failing. You should run this code after your products are retrieved from server.
Or another way not to get this error is add a check:

if (mProducts.size() > position) {
    String id = mProducts.getSingleProductId.get(position);
    String name = mProducts.getSingleProductName.get(position);
    String price = mProducts.getSingleProductPrice.get(position);
    String oldPrice = mProducts.getSingleProductOldPrice.get(position);
    String discount = mProducts.getSingleProductDiscount.get(position);
    String description = mProducts.getSingleProductDescription.get(position);
}

The crash should be gone, but you probably won't have data you need.

@Dinesh_Yogi Could you provide the code of what is `mProducts`. As I understand it's the object of your custom class – Max Zavernutiy Dec 01 '16 at 12:26
Products mProducts = new Products(); Where Products is another class – Dinesh_Yogi Dec 01 '16 at 12:31
@Dinesh_Yogi Please provide the code of `Products` class and the code where you add data to `mProducts` object – Max Zavernutiy Dec 01 '16 at 12:33
