android - Need help in POST multiple image file using retrofit?

Question

How to add multiple images/files on a same parameter along with other textual data using retrofit?

Single image is uploading perfectly using following interface
    @Multipart
    @POST("/users/updateProfile/")
    public void updateProfileWithImage(
                    @Part("user_id") TypedString first_name,
                    @Part ("image") TypedFile image, 
                    Callback<WebResponse> callback);

You can use the @MultiPart Post with @PartMap as parameter

Map<String, TypedFile> files = new HashMap<String, TypedFile>();
files.put("my file number one", new TypedFile("image/jpg", new File(filename)));
files.put("my file number two", new TypedFile("image/jpg", new File(filename)));

apiInterface.updateProfileWithImage("first name here", files);

private interface ApiInterface{
    @Multipart
    @POST("/users/updateProfile/")
    Response updateProfileWithImage(
     @Part("user_id") TypedString first_name,
     @PartMap Map<String,TypedFile> Files
    );

}
