will be helpful for those in need Yep. I normally use retrofit to make calls, then:
public class AppNameApp extends Application {
private ApiService apiService;

public void onCreate() {

public ApiService getApiService() {
    if (apiService == null) {
        apiService = 
    return apiService;

private Retrofit provideRetrofit(String url) {
    return new Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create(new Gson()))

private OkHttpClient provideOkHttpClient() {
    OkHttpClient.Builder okhttpClientBuilder = new OkHttpClient.Builder();
    okhttpClientBuilder.connectTimeout(30, TimeUnit.SECONDS);
    okhttpClientBuilder.readTimeout(30, TimeUnit.SECONDS);
    okhttpClientBuilder.writeTimeout(30, TimeUnit.SECONDS);
    return okhttpClientBuilder.build();
public interface ApiService {
String URL = "https://api.example.com" + "/v1/";

    Call<AccountInfo> getAccountInfo(@Path("accountId") String accountId);
public class HomeActivity extends AppCompatActivity{

public void onCreate(Bundle savedInstanceState) {

private void getAccountInfo() {
 ((App) getApplication()).getApiService().getAccountInfo()
      .enqueue(new Callback<AccountInfo>() {
          public void onResponse(Call<AccountInfo> call, 
   Response<AccountInfo> response) {
              if (response.isSuccessful()) {
                  // return to UI thread
                  // display AccountInfo on UI

          public void onFailure(Call<AccountInfo> call, Throwable t) {
              // skip for now

In Domain Driven Design, can services call other services?

Tag : language-agnostic , By : ponchopilate

around this issue Is your question about Domain Services, not application or infrastructure services? If so, DDD has no specific guidelines about isolating Domain Services from each other. Use your judgement and watch for SOLID violations. Also keep in mind that domain services are often misused and it makes sense to put more logic into Entities:

How should Domain Services call Infrastructure services?

Tag : development , By : enginecrew

it fixes the issue 1a) An IS can be injected into a domain service if it needs it for functionality - ie not passed to method. This is different than entities and it is because a domain service is stateless and so it can be configured with required dependencies once and used where needed, such as by other entities.
1b) A domain service should be passed to entity as argument much like you would pass a repository interface as argument. The same principles apply. Also, passing entire repository interface can create needless coupling and so it is better to declare and pass a role specific interface.

Why does No 'Access-Control-Allow-Origin' is not enforced when I call third party services, but it is when I call my own

Hope this helps
At first I thought it was a problem with my server configuration
var origin, method, headers;
origin = getRequestHeader("Origin");
if (origin /* and you want to grant access to it */) {
    addResponseHeader("Access-Control-Allow-Origin", origin);
    method = getRequestHeader("Access-Control-Request-Method");
    if (method) {
        // Note the request header is singular, but the response header is plural
        addResponseHeader("Access-Control-Allow-Methods", method);
    headers = getRequestHeader("Access-Control-Request-Headers");
    if (headers) {
        addResponseHeader("Access-Control-Allow-Headers", headers);
    if (/* You want to allow the origin to provide credentials and cookies*/) {
        addResponseHeader("Access-Control-Allow-Credentials", "true");

Ambiguous call services.AddOptions() in ConfigureServices(IServiceCollection services)

Tag : chash , By : Giles

it should still fix some issue Based on the feedback from this question I tracked down that I had a reference in project.lock.json to "EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final" which on its own has a reference to "Microsoft.Extensions.OptionsModel": "1.0.0-rc1-final"
The whole point is to have only references to "Microsoft.Extensions.Options": "1.0.0-rc2-final" and remove all the ones to OptionsModel.

Keystore configuration for calling services that call other services with different sets of certificates

Tag : java , By : Julian Ivanov

wish helps you It is not necessary for System A to keep all the Service A .. N certificates in its key store. System A should only keep the certificate of Service B to call it and then Service B should have kept the certificate of Service C in its Keystore.
