Question

项目要求：使用天蓝色移动服务在windows azure网站和Android设备之间进行通信

1）网站使用Microsoft Windows Azure（服务器端）在VB.NET中构建

2）Android应用程序位于Android设备（客户端）

客户端（Android用户）应该能够将数据从Android设备（客户端）发送到网站（服务器端），反之亦然。为了实现这一点，即客户端和服务器之间的通信我正在使用Microsoft提供的移动服务使用GCM（Google Cloud Messaging）的Windows Azure（服务器端）

我已根据文档

执行了所有步骤

http://www.windowsazure.com/en-us/develop/mobile/tutorials/get-started-with-push-android/

还按照上面Microsoft windows azure链接文档中提供的所有步骤进行操作

但是当我尝试从Android设备向网站发送消息时，会发生以下错误

错误： com.microsoft.windowsazure.mobileservices.MobileServiceException：处理请求时出错

注意：GCM（Google Cloud Messaging）为我们提供了一个gcm.jar文件，该文件在Android应用程序中用于向服务器发送数据，即网站

ONCREATE CODE

           @Override
       public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_to_do);


    GCMRegistrar.checkDevice(this);
    GCMRegistrar.checkManifest(this);
    mRegistationId = GCMRegistrar.getRegistrationId(this);
    if (mRegistationId.equals("")) {
        GCMRegistrar.register(this, SENDER_ID);
    }

    mProgressBar = (ProgressBar) findViewById(R.id.loadingProgressBar);

    // Initialize the progress bar
    mProgressBar.setVisibility(ProgressBar.GONE);

    try {
        // Create the Mobile Service Client instance, using the provided
        // Mobile Service URL and key
        mClient = new MobileServiceClient(
                "url of website",
                "POBHgxwAktyxUdeRRpcFyqEcsppwiS99",
                this).withFilter(new ProgressFilter());

        // Get the Mobile Service Table instance to use
        mToDoTable = mClient.getTable(ToDoItem.class);

        mTextNewToDo = (EditText) findViewById(R.id.textNewToDo);

        listViewToDo.setAdapter(mAdapter);

        // Load the items from the Mobile Service
        refreshItemsFromTable();
                    }

On BUTTON点击事件addItem（）被称为

            }

        }
    });

    item.setRegistrationId(mRegistationId.equals("") ?
            GCMIntentService.getRegistrationId() : mRegistationId);
    mTextNewToDo.setText("");
    }
    catch(Exception ex)
    {

    }
}

            public void checkItem(ToDoItem item) {

想出教程使用'而不是'，在我的例子中是问题。问题出在azure上的插入脚本中。希望它可以帮助你:-)
