我即将创建一个Android测试客户端，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，我的服务似乎没问题。当我运行它的诊断方法时，它看起来没问题。
诊断测试结果评论
Sync Framework运行时：已通过无
连接到SQL Server_ PASSED无
数据库供应_通过无
批处理文件夹存在？：N / A未启用批处理。
对批处理文件夹的写访问N / A：未启用批处理。
ClientAccessPolicy.xml / CrossDomain.xml文件：FAILED无法找到clientaccesspolicy.xml或crossdomain.xml文件。从其他域调用服务的Silverlight客户端将无法成功发出请求。
服务配置设置配置值
范围名称：wcfscope
默认冲突解决方案：ClientWins
默认序列化格式：ODataJson
详细错误响应：真实
批处理目录：BATCHING_NOT_ENABLED
下载批量大小BATCHING_NOT_ENABLED
我下载了唯一可用的Android示例：http://selvinlistsyncsample.codeplex.com/documentation
并据此修改。经过几个小时的痛苦，我的Android项目编译。
当我运行应用程序时，我得到以下异常。
呼唤是这样的：
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。我该怎么检查？
