Android Retrofit 2.0 JSON document was not fully consumed

Question

I am using retrofit 2.0 to post data in the form of post request with pojo class and returning string as an response either failure or success and now the problem is that it says json cannot be consumed.

compile 'com.squareup.retrofit:retrofit:2.0.0-beta2'
compile 'com.google.code.gson:gson:2.6.1'
compile 'com.squareup.retrofit:converter-gson:2.0.0-beta2'
compile 'com.squareup.okhttp:okhttp:2.4.0

Now I am trying to post jsonobect as like below. My pojo class is as below

  public class RecruiterProfileModel implements Serializable
    {
        @SerializedName("fname")
        private String firstname;
        @SerializedName("lname")
        private String lastname;
        @SerializedName("company")
        private String companyName;
        @SerializedName("address")
        private String address;
        @SerializedName("email")
        private String email;
        @SerializedName("paswd")
        private String password;
        @SerializedName("ph")
        private String phone;

        }

        public String getCompanyName() {
            return companyName;
        }

        public void setCompanyName(String companyName) {
            this.companyName = companyName;

        }

        public String getPhone() {
            return phone;
        }

        }

        public void setLandmark(String landmark) {
            this.landmark = landmark;
        }
    }

My Interface is using pojo model as body parameter and returning string response either success or failure

@POST("empowerapp/providersreg.php")
    Call<String> registerRecruiter(
            @Body RecruiterProfileModel profileModel);

My method for post request

     public void registerRecruiter(RecruiterProfileModel profileModel) {
             Gson gson = new GsonBuilder().setLenient().create();

            OkHttpClient client = new OkHttpClient();

            Retrofit retrofit = new Retrofit.Builder().baseUrl(Allconstants.MAIN_URL).client(client).addConverterFactory(GsonConverterFactory.create(gson)).build();

            RetrofitInterface service = retrofit.create(RetrofitInterface.class);

            Call<String> call = service.registerRecruiter(profileModel);
            call.enqueue(new Callback<String>() {
                @Override
                public void onResponse(Response<String> response, Retrofit retrofit) {
                    System.out.println("###coming"+response.body().toString());
                    if (response.body().toString().equalsIgnoreCase("success"))
                    {
                        pd.dismiss();
                        loginSession.createLoginSession(Allconstants.RECRUITER,Allconstants.R_REG_ACTIVITY);
                        Toast.makeText(Registration.this,"successfully registered",Toast.LENGTH_LONG).show();
                        System.out.println("###coming"+response.body().toString());
                    }else{
                        pd.dismiss();
                        Toast.makeText(Registration.this,"oops!!!something went wrong..try again",Toast.LENGTH_LONG).show();
                    }
                }

                @Override
                public void onFailure(Throwable t) {
                    pd.dismiss();
                    Toast.makeText(Registration.this,t.getStackTrace().toString(),Toast.LENGTH_LONG).show();
                    System.out.println("###error1"+t.getMessage());
                }
            });
        }

The problem now is that it says json cannot be consumed.Please help me in resolving this issue .Your help will be much appreciated. Thanks in advance

Answer 1

try adding .addConverterFactory(ScalarsConverterFactory.create()) when creating Retrofit object.

Retrofit retrofit = new Retrofit.Builder()
      .baseUrl(Allconstants.MAIN_URL)
      .client(client)
      .addConverterFactory(ScalarsConverterFactory.create())
      .build();

You'll also need to add following to your build.gradle (using version of retrofit you indicated you were using)

   implementation 'com.squareup.retrofit2:converter-scalars:2.9.0'

Answer 2

Also I found out that order also needs to be same with ScalarsConverterFactory.create

    .addConverterFactory(ScalarsConverterFactory.create()) //important
    .addConverterFactory(GsonConverterFactory.create(gson))

It wont work if GSON is on top like following :

    .addConverterFactory(GsonConverterFactory.create(gson))
    .addConverterFactory(ScalarsConverterFactory.create()) //important
