java - Android Rest Api Post 400 bad request -

i'm working on app send password server check if it's correct, server return 0,1,2,3 representing different statuses i'm not sure 400 bad request coming from. i've called server , received json file i'm suspecting it's how parsed it? appreciated.

an update

an update. realize part of mistake here i'm trying send string without converting json file first. why i've been receiving "status:0" stands error occurred. i've converted string registerrequest object contains string variable. i'm receiving status 2 stands incorrect password. bad request 400 still remains. please or suggestion helpful me

@headers("content-type: application/json") @post("removed/{id}") registerresponse registerevent(     @path("id") int id,      @body registerrequest password ) throws networkexception; 

registerresponse class:

public class registerresponse {     public string status; } 

registerrequest class

public class registerrequest {      string passcode ;      public registerrequest(string passcode)     {         this.passcode=passcode;     } } 

call server:

try {     registerresponse response = networkhelper.makerequestadapter(this)                .create(testapi.class).register(id, pass);          if(response.status=="1"||response.status=="3")         {             return true;         }         else             return false;     } catch (networkexception e) {         e.printstacktrace();     }    return false; } 

make request adapter

private static restadapter.builder makerequestadapterbuilder(final context context, errorhandler errorhandler, string datetimeformat)     {         requestinterceptor requestinterceptor = new requestinterceptor()         {             @override             public void intercept(requestinterceptor.requestfacade request)             {                 request.addheader("authorization", appprefs.getinstance(context).getsessiontoken());             }         };          gson gson = new gsonbuilder().setdateformat(datetimeformat).create();         gsonconverter gsonconverter = new gsonconverter(gson);          restadapter.builder builder = new restadapter.builder()                 .setrequestinterceptor(requestinterceptor).setconverter(gsonconverter)                 .setloglevel(restadapter.loglevel.full).setlog(new androidlog("boom!"))                 .setendpoint(base_url);          if(errorhandler != null)         {             builder.seterrorhandler(errorhandler);         }          if(instance == null)         {             instance = new okclient(maketimeoutclient(read_timeout, connect_timeout));         }         builder.setclient(instance);          return builder;     }

i've figured out. handling wrong exception , api returning 400 instead of 401 senting wrong passcode. i've changed call server network exception error exception error.

thank help.
