Retrofit 2.0-beta-2 is adding literal quotes to MultiPart values

Question

Went to upgrade to Retrofit 2.0 and running into this weird problem.

I have a method to log a user in

public interface ApiInterface {

    @Multipart         


        

Answer 1

I've found another one solution except those. Worked with Retrofit 2.1.0. (Rx adapter is optional here)

My retrofit interface looks like this:

@POST("/children/add")
Observable addChild(@Body RequestBody requestBody);

And in ApiManager I use it like this:

@Override
    public Observable addChild(String firstName, String lastName, Long birthDate, @Nullable File passportPicture) {
        MultipartBody.Builder builder = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("first_name", firstName)
                .addFormDataPart("last_name", lastName)
                .addFormDataPart("birth_date", birthDate + "");

        //some nullable optional parameter
        if (passportPicture != null) {
            builder.addFormDataPart("certificate", passportPicture.getName(), RequestBody.create(MediaType.parse("image/*"), passportPicture));
        }
        return api.addChild(builder.build());
    }

It is similar to Solution1 from Loyea but I think that it's little a bit more elegant.
