java - Uber Refresh Authenticator crash -

-

my app receives accesstoken, refreshtoken, expirytimeinmillis after doing uber websetup. these storing in file via storedcredential. whenever have create session create credential follows reading values stored in storedcredential.

private credential createcredential(){     credential.builder builder = new credential.builder(new credential.accessmethod() {         @override         public void intercept(httprequest request, string accesstoken) throws ioexception {             /**              * nothing              */         }          @override         public string getaccesstokenfromrequest(httprequest request) {             /**              * nothing              */             return null;         }     });     builder.settransport(new mockhttptransport());     builder.setjsonfactory(new mockjsonfactory());     builder.setclientauthentication(new basicauthentication("user","pass"));      string query = "";     try {         query = urlencoder.encode("mock", "utf-8");     } catch (unsupportedencodingexception e) {         log.v(tag,"unsupportedencodingexception ");     }     string url = "http://mockaddress.com/search?q=" + query;     builder.settokenserverencodedurl(url);     return builder.build(); }   public void setcredentialsfromwebsetup(string accesstoken, string refreshtoken, long expire_at){     credential = createcredential();     credential.setaccesstoken(accesstoken);     credential.setrefreshtoken(refreshtoken);     credential.setexpirationtimemilliseconds(expire_at); }

my problem is:

  1. the accesstoken expired, , don't know how renew using refreshtoken.

  2. i thought uber sdk handles renewing accesstoken passing accesstoken, refreshtoken, expirytime, looking @ uber-java-sdk code.

  3. how notified of new accesstoken after renewed using refreshtoken.

i don't have client login uber. don't have uber app on device. using uber-rides-java sdk build app uses uber api's book/cancel/view ride details.

i seeing crash , not available related problem.

it looks you're using the uber java sdk on android. please utilize uber android sdk not utilize google oauth credential class, , has lighter weight implementation.

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i...

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
