Can not access to the path using dynamic retrofit in android

Question

I'm new working with retrofit in android, I have read the following links:

https://github.com/codepath/android_guides/wiki/Consuming-APIs-with-Retrofit https://inthecheesefactory.com/blog/retrofit-2.0/en Is it possible to manipulate retrofit url without method parameter?

But I can not make my code working. Any help is very good recived.

My service ProductInfo:

import java.util.List;
import retrofit2.Call;
import retrofit2.http.GET;
import retrofit2.http.Path;

public interface ProductInfo {
@GET("api/keyIndicator/{id}/")
Call<List<ProductManager>> getFindProduct (@Path(value = "id") String 
productId);
}

My method inside my java class:

private void FillInfoProduct(String cveProduct) {

 String baseUrl = "http://SOMEURL/";

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(baseUrl)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    ProductInfo productInfo = retrofit.create(ProductInfo.class);

  Call<List<ProductManager>> productId = 
  productInfo.getFindProduct(cveProduct);

    productId.enqueue(new Callback<List<ProductManager>>() {
        @Override
        public void onResponse(Call<List<ProductManager>> call, 
 Response<List<ProductManager>> response) {
            System.out.println("FINDED");

            if (response.isSuccessful()) {
                productFinded=response.body();
            }
        }

        @Override
        public void onFailure(Call<List<ProductManager>> call, Throwable t) {
            System.out.println("NOT FINDED");
        }
    });

}

The JSON I recive:

 [{"Id":1,"Name":"Product1","Price":9.99}, 
 {"Id":2,"Name":"Product2","Price":19.99}, 
 {"Id":3,"Name":"Product3","Price":29.99}, 
 {"Id":4,"Name":"Product4","Price":39.99}, 
 {"Id":5,"Name":"Product5","Price":49.99},
 ...]

I wanna access to the id URL, something like this:

http://SOMEURL/api/keyIndicator/1
http://SOMEURL/api/keyIndicator/2
.
.
.
http://SOMEURL/api/keyIndicator/1000

And read:

 {"Id":1,"Name":"Product1","Price":9.99}
 {"Id":2,"Name":"Product2","Price":19.99}

etc

The logcat always return: NOT FINDED THERE IS NO ERROR. I always access to the onFailure method.
