        System.out.println(contact);

        // Ask the service to insert the new entry

            return myService.insert(postUrl, contact);



        }
        catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
        return contact;
    }

当我使用此代码时，它会出现以下错误： [错误] [simplerpc] - 第9行：没有源代码可用于com.google.gdata.data.contacts.ContactEntry类型;你忘了继承一个必需的模块吗？

Answer 1

当我使用此代码时，它会给出错误
