android - Recursive Retrofit Call -

i'm uploading files server using hawk authentication , retrofit 1.6 on android. need handle case devices clock out of sync server time. when make first request if timestamp out of sync server respond 401 , supply correct server time in response. adjust client timestamp , resubmit. approach recursively within callback's failure(). problem recursive call timing out 95% of time , succeeds 5% of time. suspect there deadlocking issue recursive call , request/response threads. i'm not setting executor threads rather using default. illustrates restadapter , basic call flow (shortened brevity). can suggest going on , how solve this?

public static restadapter getretrofitadapter(final map<string, string> headers) {     requestinterceptor requestinterceptor = new requestinterceptor() {         @override         public void intercept(requestfacade request) {              if (headers != null) {                 (string key : headers.keyset()) {                     request.addheader(key, headers.get(key));                 }             }         }     };      okhttpclient client = new okhttpclient();     cookiemanager cookiemanager = new cookiemanager();     cookiemanager.setcookiepolicy(cookiepolicy.accept_all);     client.setreadtimeout(60, timeunit.seconds);     client.setconnecttimeout(60, timeunit.seconds);     client.setcookiehandler(cookiemanager);      final restadapter restadapter = new restadapter.builder()             .setendpoint(url)             .setrequestinterceptor(requestinterceptor)             .setloglevel(restadapter.loglevel.full)             .setclient(new okclient(client))             .build();      return restadapter; }   public void uploadmedia(final string localfilename, final uploadcallback callback, final context context) {     try {         map<string, string> headers = generatehawkauthorizationheader(mediapath, http_post);         restadapter restadapter = getretrofitadapter(headers);         mediauploadservice service = restadapter.create(mediauploadservice.class);          file localfile = new file(localfilename);         if (localfile.exists()) {             typedfile mediafile = new typedfile("multipart/form-data", new file(localfilename));             callback<media> callback = new callback<media>() {                 @override                 public void success(media media, response response) {                     callback.onuploadresponse(media, response.getstatus());                 }                  @override                 public void failure(retrofiterror error) {                     if (error != null && error.getresponse() != null && error.getresponse().getstatus() == 401){                         if(hastimedifference((jsonelement)) {                             adjusttimestamp();                             uploadmedia(localfilename, callback, context);                         }                     }                         else {                         int statuscode = error.getresponse() != null ? error.getresponse().getstatus() : -1;                         callback.onuploadresponse(null, statuscode);                     }                 }             };             service.uploadmedia(mediafile, callback);         } else {             callback.onuploadresponse(null, 404);         }     } catch (exception e) {} }
