case 1. (Which I had done)

Answer 1

We can add all request parameter in multipart body builder with specified type like in below one image file. I have set media type parse multipart/form-data and some other parameter I have set media type parse text/plain. This builder will build to make Multipart Body and can send by using body annotation in multipart body.

@Multipart
@POST("user/update")
Call addDocument(@@Part MultipartBody file);


final MultipartBody.Builder requestBodyBuilder = new MultipartBody.Builder()
      .setType(MultipartBody.FORM);

requestBodyBuilder.addFormDataPart("doc_image_file", imageFile.getName(),
      RequestBody.create(MediaType.parse("multipart/form-data"), imageFile));
requestBodyBuilder.addFormDataPart("user_id", null, RequestBody.create(MediaType.parse("text/plain"),"12"));
requestBodyBuilder.addFormDataPart("doc_name", null, RequestBody.create(MediaType.parse("text/plain"),"myfile"));
requestBodyBuilder.addFormDataPart("doc_category", null, RequestBody.create(MediaType.parse("text/plain"),category));
requestBodyBuilder.addFormDataPart("doc_image_file", imageFile.getName(),RequestBody.create(MediaType.parse("multipart/form-data"),imageFile));
requestBodyBuilder.addFormDataPart("doc_text_content", null, RequestBody.create(MediaType.parse("text/plain"),body));
RequestBody multipartBody = requestBodyBuilder.build();
