android - Uber request error -

i using uber book cab in application. got price list , authenticated access token. after trying book cab using request api.

i included request scope.

this code call request api:

private void bookuber(string selectedproductid,string token,double startlatitude,double startlongitude,             double endlatitude,double endlongitude) {          uberapiclient.getsandbox().getrequest(token, selectedproductid,                 startlatitude, startlongitude, endlatitude, endlongitude,                 new ubercallback<ubermodel>() {                     @override                     public void success(ubermodel ubermodel, response response) {                         super.success(ubermodel, response);                         log.e("ubermodel", ubermodel.tostring());                         log.e("response", "" + response);                     }                      @override                     public void failure(retrofiterror error) {                         log.e("bookuber error ", "" + error);                         super.failure(error);                     }                 });      } 

request method:

 @post("/requests")     void getrequest(@header("authorization") string authtoken,                     @query("product_id") string productid,                     @query("start_latitude") double startlatitude,                     @query("start_longitude") double startlongitude,                     @query("end_latitude") double endlatitude,                     @query("end_longitude") double endlongitude,                     callback<ubermodel> callback);

finally got answer. may useful answer in future. referred this.

i have changed request method:

@post("/requests") void getrequest(@header("authorization") string authtoken,                 @body hashmap<string, string> obj,                 callback<ubermodel> callback); 

method call api:

private void bookuber(string selectedproductid,string token,double startlatitude,double startlongitude,             double endlatitude,double endlongitude) {         hashmap<string, string> obj=new hashmap<string, string>();             obj.put("product_id", selectedproductid);             obj.put("start_latitude", string.valueof(startlatitude));             obj.put("start_longitude", string.valueof(startlongitude));             obj.put("end_latitude", string.valueof(endlatitude));             obj.put("end_longitude", string.valueof(endlongitude));              uberapiclient.getsandbox().getrequest(token, obj,                     new ubercallback<ubermodel>() {                         @override                         public void success(ubermodel ubermodel, response response) {                             super.success(ubermodel, response);                             log.e("response", "" + response.tostring());                         }                          @override                         public void failure(retrofiterror error) {                             log.e("uber price list error ", "" + error);                             super.failure(error);                         }                     });      }
