Create Completion handler interface like IOS

Question

I am working on an android application to which I have integrated 20 APIs using AsyncHttpClient, for every API call I have to implement these two below methods to get the Response whether it is success hit or failure.

client.post(context,url,null,AppConstant.APPLICATION_JSON_CONTENT,new AsyncHttpResponseHandler(){

@Override
public void onSuccess(int statusCode,cz.msebera.android.httpclient.Header[]headers,byte[]responseBody){

        }


@Override
public void onFailure(int statusCode,cz.msebera.android.httpclient.Header[]headers,byte[]responseBody,Throwable error){


        }
        });

I want to remove replication of these two methods from every activity on every API call.

Is it possible to create a class or interface to which I will pass on the URL, request parameters and header etc. required for API call and there I will define these two methods and this class/interface will be accessed for every API call. in return, it will provide me the response of the API

You can create your own instance of your own class which implements such interface. In order to store this instance you can use either singleton pattern or a value inside Application class (or instance)

By the way, you can use a custom parent class which implements wanted interface and hide some implementations.
