Create 3 packages folders - 1. contractor  2. Model  3. controller   




1.

In contractor package folder - We will create interfaces  1. For View All Products  2. For Get All Products.




In “For View All Products” interface - create abstract methods. One Method type - array




2.




Define variables in Model class and create getter and setter methods.




3.




Create a Class and Implement “Get All Products” interface in it

Define context and View All Products interface.

Create constructor - Pass context and assign context to View All Products interface.

Define Request Queue.

Implement “Get All Products” interface method.

Write Hit API code under “Get All Products” interface method.




Hit API - 




Define API URL.

Make object of Request Queue.

Make object of String Request.
