By the reference of This answer I made changes like this and its working fine.

Request

RequestBody requestBody = RequestBody.create(MediaType.parse("*/*"), file);
        MultipartBody.Part fileToUpload = MultipartBody.Part.createFormData("image", file.getName(), requestBody);
        MultipartBody.Part id = MultipartBody.Part.createFormData("userId", userId);
        //Creating a rest adapter
        ApiInterface apiService =
                ApiClient.getClient().create(ApiInterface.class);

        Call<ProfilePicUpdateResponse> call = apiService.updateProfilePic(id,fileToUpload);
        call.enqueue(new Callback<ProfilePicUpdateResponse>() {
            @Override
            public void onResponse(Call<ProfilePicUpdateResponse> call, Response<ProfilePicUpdateResponse> response) {

                loading.dismiss();
                if (response.isSuccessful()) {
                    Log.e("Success", new Gson().toJson(response.body()));
                }
                else
                {
                    loading.dismiss();
                    csActivity.showMsg(getResources().getString(R.string.something_error));
                }
            }

            @Override
            public void onFailure(Call<ProfilePicUpdateResponse> call, Throwable t) {

                loading.dismiss();
                Log.d("=========>>", t.getMessage().toString());
                Log.d("============>>>", "Failure");
            }
        });

InterfaceClass

 @Multipart
    @POST("AccountService/MultipartProfileImageUpload")
    Call<ProfilePicUpdateResponse> updateProfilePic(@Part MultipartBody.Part userId, @Part MultipartBody.Part file);
