        Next we need to create and build a Request. Declare a new Request variable,
        and then set it by chaining a few methods together.
        First use new Request.Builder(), then chain the url() method using apiUrl as the parameter.
        Then chain build() to finish.

                Request request = new Request.Builder().url(apiUrl).build();

        // execute the call:
        try {
            //We have an execute method from our call class, and it returns a response object.
            //So let's store that response in a variable:
            Response response = call.execute();
            //add this //now we want to check if the request is successful (there is a handy method from the response class):
            if (response.isSuccessful()){
            Log.v(TAG, response.body().string());//Log entire response body
