我即将创建一个 Android 测试客户端，它尝试与运行 MS Sync Framework 的服务器同步。
我配置了数据库并创建了必要的 WCF 文件，在浏览器中，我的服务似乎还可以。当我运行它的诊断方法时，它看起来还不错。
诊断测试结果注释
同步框架运行时：通过无
连接到 SQL Server_通过无
数据库配置_通过无
批处理文件夹存在？：不适用批处理未启用。
对批处理文件夹的写入权限 不适用：批处理未启用。
ClientAccessPolicy.xml/CrossDomain.xml 文件：失败找不到 clientaccesspolicy.xml 或 crossdomain.xml 文件。从另一个域调用服务的 Silverlight 客户端将无法成功发出请求。
Service ConfigurationSetting 配置值
范围名称：wcfscope
默认冲突解决：ClientWins
默认序列化格式：ODataJson
详细错误响应：true
批处理目录：BATCHING_NOT_ENABLED
下载批处理大小 BATCHING_NOT_ENABLED
我下载了唯一可用的 Android 示例：http
://selvinlistsyncsample.codeplex.com/documentation
并进行了相应修改。经过几个小时的磨难，我的 Android 项目编译成功。当我运行应用程序时，我得到以下异常。调用是这样的：
Uri uri = MyProviderClass.getSyncUri("WCFScopeSyncService", "WCFScope");
ContentResolver res = context.getContentResolver();
int result = res.update(uri, null, null, null);
在服务器端，日志中没有错误。我应该检查什么？
