Retrofit2 : How to upload image with JSONObject in android

Question

I'm trying to post JSONObject with one image which is taken by camera run time. how to post an Image using retrofit in android. This is my Interface

 @Multipart
@POST("/upload")
Call<Response> getDetails(@Part("empsno") String  empsno,
                                @Part("time")String deliveryTime,
                                @Part("uploadFile") MultipartBody.Part part,
                                @Part("remarks")String remarks,
                                @Part("receiver")String receivedBy,
                                @Part("Address")String ipAddress
                                );

code i used to upload image with other details

 JSONObject oJSONObject = new JSONObject();
        oJSONObject.put("empsno", strEmpsno);
        oJSONObject.put("time", strtime);
        oJSONObject.put("remarks", strRemarks);
        oJSONObject.put("receiver", strReceiver);
        oJSONObject.put("Address", straddress);
        oJSONObject.put("uploadFile", imageFolderPath + "/" + imageName);

RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
MultipartBody.Part body = MultipartBody.Part.createFormData("uploadFile", file.getName(), requestFile);

xInterface interface = retrofit.create(xInterface.class);
Call<Response> podResponsecall = interface.getDetails(strEmpsno, strtime,
                body, strRemarks, strReceiver, straddress);


  podResponsecall.enqueue(new Callback<Response>() {
            @Override
            public void onResponse(Response<Response> response) {
                String val = response.body() + "";
                Log.e(TAG, "onResponse: " + val);
            }

            @Override
            public void onFailure(Throwable t) {
                Log.e(TAG, "onFailure: " + t.getLocalizedMessage());
            }
        });

Output - onFailure: JSON must start with an array or an object.

I don't know weather this is right or wrong. Please help me to post some images as well as other details using Retrofit2 beta 3.

Service.class :

    @Multipart
    @POST("upload")
    Call<Void> upload(@Part("model") RequestBody model,  @Part MultipartBody.Part file);

Retrofit 2 part :

    Gson gson = new GsonBuilder().setLenient().create();
    RequestBody modelBody = RequestBody.create(MediaType.parse("application/json"), gson.toJson(modelPojo));
    RequestBody reqFileBody = RequestBody.create(MediaType.parse("multipart/form-data"), file);
    MultipartBody.Part mPart1 = MultipartBody.Part.createFormData("file","name",reqFileBody);

Java Spring :

   @PostMapping(value="/upload" ,consumes = {"multipart/form-data","application/json"})
    public ResponseEntity<Object> uploadImagebyEmail(@RequestPart("model") Object model,@RequestPart("file") MultipartFile uploadfile  ) throws IOException {
    return //codes here...   
    }

is it possible to send only one POJO containing Multipart Image and other Parameters like String? If it;s possible, how can i do it? — Avi Patel, Nov 18 '18 at 18:47
You may dispatch images as a base64 string in an object otherwise i do not know any way. — Photon Point, Nov 19 '18 at 08:13

Replace

@Multipart
@POST("/upload")
Call<ResponseBody> getDetails(@Part("empsno") RequestBody empsno,
                                @Part("time")RequestBody deliveryTime,
                                @Part("uploadFile") MultipartBody.Part part,
                                @Part("remarks")RequestBody remarks,
                                @Part("receiver")RequestBody receivedBy,
                                @Part("Address")RequestBody ipAddress
                                );

And also in

Call<ResponseBody> podResponsecall = interface.getDetails(strEmpsno, strtime,
                body, strRemarks, strReceiver, straddress);

RequestBody - is it pojo class? – AMAN SINGH Sep 05 '16 at 10:37
but here i'm using here **strEmpsno** is in string format – AMAN SINGH Sep 05 '16 at 10:45
all i need to change it into RequestBody like RequestBody empsno = RequestBody.create(MediaType.parse("multipart/form-data") , strEmpsno); – AMAN SINGH Sep 05 '16 at 10:47
I tried the way you suggest but getting null in response.body() – AMAN SINGH Sep 05 '16 at 10:57
