Retrofit 2 parsing outgoing data

Question

Hello Stackoverflow's Guys! This is my first post and really is my Big problem with Retrofit 2 I hope Some guys help to solving that.

this is my Interface class:

public interface PicUploadInterface {
@Multipart
@POST("user")
Call<UserModelResponse> uploadMultipleFiles(@Part("Authorization")  RequestBody authorization,
                          @Part("description") RequestBody description,
                          @Part MultipartBody.Part filePart);

and apimanager class:

public class Apimanager {

public static void upload(String coda, File file) {
    // create upload service client
    final String API_BASE_URL = "http://10.0.3.2/web2Demo/public/";
    OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

    HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
    // set your desired log level
    logging.setLevel(HttpLoggingInterceptor.Level.BODY);
    httpClient.addInterceptor(logging);  

    Retrofit builder =
            new Retrofit.Builder()
                    .baseUrl(API_BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(httpClient.build())
                    .build();

    PicUploadInterface service = builder.create(PicUploadInterface.class);
    RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);

    MultipartBody.Part filePart  = MultipartBody.Part.createFormData("uploaded_file", file.getName(), requestFile);

    String descriptionString = coda;
    String AuthString = "Send picture";
    RequestBody description = RequestBody.create(MediaType.parse("text/plain"), descriptionString);
    RequestBody authorization = RequestBody.create(MediaType.parse("text/plain"), AuthString);

    Call<UserModelResponse> call = service.uploadMultipleFiles(authorization, description, filePart);
    call.enqueue(new Callback<UserModelResponse>() {
        @Override
        public void onResponse(Call<UserModelResponse> call,
                               Response<UserModelResponse> response) {
            Log.v("Upload", "success");
        }
        @Override
        public void onFailure(Call<UserModelResponse> call, Throwable t) {
            Log.e("Upload error:", t.getMessage());
        }
    });
}

and i using code in this way:

      File file = new File(textViewFile.getText().toString()); // getting this string "/storage/emulated/0/bichooser/1476172212892.jpg"
      connectivity.com.pack.Apimanager.upload(name, file);

and finally my HttpLoggingInterceptor show this that I cannt find what is and how pars it in my restApi

I can't find what is going out from retrofit 2.1.0 to my restApi and which part is my string or image data? I did change many time based on stackoverflow tips and another site but my result was almost same! ( i did short image binary outgoing from interceptor log) If someone have idea please share that. Thanks

indeed my big problem in posting data and in this time response isnot important for me. — CodeSqueezer

Have you tried using directly in your service call:

RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);

...

Call<UserModelResponse> call = service.uploadMultipleFiles(authorization, description, requestFile);

And updating this:

@Multipart
@POST("user")
Call<UserModelResponse> uploadMultipleFiles(@Part("Authorization")  RequestBody authorization,
                          @Part("description") RequestBody description,
                          @Part("file\"; filename=\"myFilename\" ") RequestBody filePart);

Another thing, if you want to see your calls to your restApi you could use Charles Proxy as a reverse proxy and see your calls and responses.
