5. But

6. This entry’s target is enterprise services.

7. Sounds logical. I agree to you only if enterprise services.

8. For normal mobile app • Almost all services have no

   proxy • Need real time update!(messaging app or game) • Need low energy consumption! > If you make long polling system, the user say 　“Battery fire!” and put 1 star...

9. Use WebSocket in peace ;-)

10. Do you know okhttp-ws?

11. Sample code • My sample Android project https://github.com/kaelaela/WebSockcetSample

12. okhttp-ws

13. Update of okhttp-ws • Add to main repos on v3.5.0!!(SNAPSHOT

    now) 　PR: #2852 　　　https://github.com/square/okhttp/pull/2852 compile 'com.squareup.okhttp3:okhttp-ws:3.4.1' compile 'com.squareup.okhttp3:okhttp:3.5.0'

14. Update of okhttp-ws • Remove ws package • Add method

    to OkHttpClient okhttp3.ws.* -> okhttp3.* newWebSocketCall

15. Sample code diff • 3.4.1 -> 3.5.0 https://github.com/kaelaela/WebSockcetSample/commit/45b88ad2ecc5a89dbd493 fc3cc25152511e28529

16. Echo test: websocket.org

17. Echo test: websocket.org Supports TLS.

18. Retrofit? -> No change. It will be added in v2.2!!!

    (No due date. 31% complete at 2016-09-16.) • Issue #924 • Commit interface Service { @GET("/chat/{id}") Call<WebSocket> chat(@Path("id") String id); }

19. Let’s replace your http client with okhttp! If your project

    use okhttp.
