android - How to get malformed JSON in Retrofit 2 -

i sending request, getting exception, though request successful(the api interacting with, sends otp on success).

the exception is:

com.google.gson.stream.malformedjsonexception: use jsonreader.setlenient(true) accept malformed json @ line 1 column 2 path $             @ com.google.gson.stream.jsonreader.syntaxerror(jsonreader.java:1573)             @ com.google.gson.stream.jsonreader.checklenient(jsonreader.java:1423)             @ com.google.gson.stream.jsonreader.dopeek(jsonreader.java:575)             @ com.google.gson.stream.jsonreader.peek(jsonreader.java:429)             @ com.google.gson.internal.bind.typeadapters$13.read(typeadapters.java:349)             @ com.google.gson.internal.bind.typeadapters$13.read(typeadapters.java:346)             @ com.google.gson.typeadapter.fromjson(typeadapter.java:256)             @ retrofit.gsonconverter.frombody(gsonconverter.java:42)             @ retrofit.okhttpcall.parseresponse(okhttpcall.java:144)             @ retrofit.okhttpcall.access$000(okhttpcall.java:25)             @ retrofit.okhttpcall$1.onresponse(okhttpcall.java:90)             @ com.squareup.okhttp.call$asynccall.execute(call.java:168)             @ com.squareup.okhttp.internal.namedrunnable.run(namedrunnable.java:33)             @ java.util.concurrent.threadpoolexecutor.runworker(threadpoolexecutor.java:1080)             @ java.util.concurrent.threadpoolexecutor$worker.run(threadpoolexecutor.java:573)             @ java.lang.thread.run(thread.java:856) 

now how see malformed json? in order know if json object malformed, if object being returned(which expecting string) , or object sending.

forgive me if trivial question, started android development, of week.

here service:

public static enrollmentapiinterface getapiclient(){     if (enrollmentrequest == null) {         okhttpclient client = new okhttpclient();         client.interceptors().add(new interceptor() {             @override             public response intercept(chain chain) throws ioexception {                 response response = chain.proceed(chain.request());                  request request = chain.request();                 buffer buffer = new buffer();                 request.body().writeto(buffer);                 string body = buffer.readutf8();                 log.println(10, tag, body);                 log.i(tag, "hello:        " + response);                  string bodystring = response.body().string();                 log.i(tag, bodystring);                 response = response.newbuilder()                     .body(responsebody.create(response.body().contenttype(), bodystring))                     .build();                 return response;             }         });          gson gson = new gsonbuilder()             .setdateformat("yyyy-mm-dd't'hh:mm:ssz")             .create();          retrofit retrofit = new retrofit.builder()             // .baseurl("http://10.0.2.2:6543/") // on avd             .baseurl("http://192.168.0.106:6543") // on device             .addconverterfactory(gsonconverterfactory.create(gson))             .build();          enrollmentrequest = retrofit.create(enrollmentapiinterface.class);     }     return enrollmentrequest; } 

interface:

public interface enrollmentapiinterface {          @headers({             "accept: application/json",             "content-type: application/json"         })         @post("auth/enroll")         call<string> requestenrollment(@body jsonobject enrollmentdetails);          @headers({             "accept: application/json",             "content-type: application/json"         })         @post("auth/enroll/auth")         call<string> authoriseenrollment(@body jsonobject logindetails);       } } 

and here call:

enrollmentrequest request = new enrollmentrequest();     request.setmsisdn(msisdntxt.gettext().tostring());     request.setid_number(idnumbertxt.gettext().tostring());     enrollmentapiclient.enrollmentapiinterface service = enrollmentapiclient.getapiclient();     log.i(tag, "request:   " + request.tojson());     call<string> call = service.requestenrollment(request.tojson());     call.enqueue(new callback<string>() {         @override         public void onresponse(response<string> response) {             log.i(tag, "on response" + response);             log.i(tag, "on response body" + response.body());             // create object of sharedpreferences.             sharedpreferences sharedpref = preferencemanager.getdefaultsharedpreferences(that);             //now editor             sharedpreferences.editor editor = sharedpref.edit();             //put value             editor.putstring("idnumber", idnumbertxt.gettext().tostring());             editor.putstring("msisdn", msisdntxt.gettext().tostring());              //commits edits             editor.commit();             log.i(tag, "onclick-after");             intent intent = new intent(getapplicationcontext(), authoriseactivity.class);             startactivity(intent);          }          @override         public void onfailure(throwable t) {             // comes in here             log.i(tag, "nothere", t);             log.d("callback", " throwable " + t.tostring());              toast.maketext(enrollactivity.this, "request failed", toast.length_long).show();         }      }); 

just log network responses, see what's wrong.

@override public response intercept(chain chain) throws ioexception {     response response = chain.proceed(chain.request());     log.w("retrofit@response", response.body().string());     return response; }
