PUT not working properly from my android project but working from Postman

I am trying to send a hashmap to the server. I am able to PUT the contents of the hashmap from Postman but I am unable to do the same from my android project. The callback first executes Onfailure. On second attempt to send the same data, I get a 409 conflict response.

The stacktrace of the failure:

08-21 14:42:19.748 9876-9876/com.example.vishwa.postingdata W/System.err: java.io.EOFException: End of input at line 1 column 1 path $

The interface:

public interface APIService {

@POST("/posts")
@FormUrlEncoded
rx.Observable<Post> savePost(@Field("id") long id,
                             @Field("title") String title,
                             @Field("author") String author);

@PUT("/posts/{id}")
@FormUrlEncoded
Call<Post> updatePost(@Path("id") long id,
                      @Field("title") String title,
                      @Field("author") String author);
@DELETE("/posts/{id}")
Call<Post> deletePost(@Path("id") long id);

@PUT("authenticate/create")
Call<HashMap<String,String>> signUpParent(@Body HashMap<String,String> hashMap);
}

The function to post:

private void PostData(HashMap<String, String> hashMap) {
    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("http://coreapi.xxxxx.org:8080/v1/")
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    APIService apiService =retrofit.create(APIService.class);

    apiService.signUpParent(hashMap).enqueue(new retrofit2.Callback<HashMap<String, String>>() {
        @Override
        public void onResponse(retrofit2.Call<HashMap<String, String>> call, Response<HashMap<String, String>> response) {
            Integer code=response.code();
            Toast.makeText(getBaseContext(),"checking the response : "+code,Toast.LENGTH_LONG).show();
            Log.i("success", "post submitted to API imaginators: ");
        }

        @Override
        public void onFailure(retrofit2.Call<HashMap<String, String>> call, Throwable t) {
            Log.e("failure", "Unable to submit post to API imaginators.");
            t.printStackTrace();
        }
    });
}

The request body given in the postman:

{
"clientid":"##########",
"email":"IAzMzkaksB8KGT2SLJsol7Xr9Phts/G8",
"first_name":"Eswar",
"last_name":"",
"password":"Dt9keQfZMUY=",
"security_answer":"",
"security_question":"",
"account_type":"learning_pod_app"
}

I have found some solutions from these links: one, two, three... But they don't work.

Any help is appreciated.

Change your method signature to:

@Headers("Content-Type: application/json")
@PUT("authenticate/create")
Call<HashMap<String,String>> signUpParent(@Body HashMap<String, String> hashMap);

If the response is empty you can use.

@Headers("Content-Type: application/json")
@PUT("authenticate/create")
Call<ResponseBody> signUpParent(@Body HashMap<String, String> hashMap);

And give it a try.

in onFailure method, capture Throweble with Log.e("failure", t.toString());

Then you can find the exact problem with the respond.
