How to pass extra post data when using Multipart in Retrofit?

Question

I'm Using the below code in Android, retrofit, to upload an image:

 @Multipart 
 @POST("uploadimage") 
 Call<ImageUploadResponse> uploadImage(@PartMap Map<String, RequestBody> map);

But what if I need to send extra data, such as Image Description along with the request?

I Was not able to use @Field, that is i tried like this:

@Multipart 
@FormUrlEncoded
@POST("uploadimage") 
Call<ImageUploadResponse> uploadImage(@PartMapMap<String,RequestBody> map,
@Field("description")String desc);

I got an error stating that only one annotation is allowed. That is either @Multipart or @FormUrlEncoded.

You can use @Part instead of @Field

@Multipart 
@POST("uploadimage") 
Call<ImageUploadResponse> uploadImage(@PartMap Map<String, RequestBody> map, @Part("description") String description);

you can look into this question for that https://stackoverflow.com/q/6694839/6207294 – shb Oct 21 '18 at 12:36
Quite not clear, but for now I'm going with @Headers, since i know to handle them in php. – Reejesh PK Oct 21 '18 at 12:44
