How to post array in retrofit android

Question

How can I post following parameter in retrofit through post method ?

 \"params\":{\"body\": {
    \"learning_objective_uuids\": [
      \"ED4FE2BB2008FDA9C81         


        

Answer 1

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

Better solution : Use arraylist.. Reference link : johnsonsu

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