Answer 1

There is a correct way of uploading a file with its name with Retrofit 2, without any hack:

Define API interface:

@Multipart
@POST("uploadAttachment")
Call uploadAttachment(@Part MultipartBody.Part filePart); 
                                   // You can add other parameters too

Upload file like this:

File file = // initialize file here

MultipartBody.Part filePart = MultipartBody.Part.createFormData("file", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));

Call call = api.uploadAttachment(filePart);

This demonstrates only file uploading, you can also add other parameters in the same method with @Part annotation.
