Answer 1

@FormUrlEncoded
@POST("service_name") 
   void functionName(
        @FieldMap Map<String, String> learning_objective_uuids, @FieldMap Map<String, String> user_uuids, @Field("note") String note,
        Callback<CallBackClass> callback
    );

Better solution : Use arraylist.. Reference link : johnsonsu

@FormUrlEncoded
    @POST("service_name") 
       void functionName(
            @Field("learning_objective_uuids[]") ArrayList<String> learning_objective_uuids, @Field("user_uuids[]") ArrayList<String> user_uuids, @Field("note") String note,
            Callback<CallBackClass> callback
        );
