Azure移动服务Android离线示例-“ createdAt”，“ updatedAt”列为空

Question

i have added in the ToDoItem table of the local DB of the mobile device the columns "createdAt" and "updatedAt", because they also exist in the Azure Database ToDoItem table. Those columns are never updated in the localstorage table although i refresh the list (the other table columns are updated normally). Why could this happen? The example i followed is here: http://azure.microsoft.com/blog/2014/08/07/offline-support-in-azure-mobile-services-android-sdk/

Thank you

Without having seen any of your code I assume you haven't decorated the CreatedAt and UpdatedAt properties with the corresponding annotations. Make sure your properties look like this and it should work:

    [Microsoft.WindowsAzure.MobileServices.CreatedAt]
    public DateTimeOffset? CreatedAt { get; set; }

    [Microsoft.WindowsAzure.MobileServices.UpdatedAt]
    public DateTimeOffset? UpdatedAt { get; set; }

Ps. you don't have to add these columns of your aren't using them.
