Windows Azure Website Communicate with Android Device

Question

Requirement of project: communication between windows azure Website and android device using azure mobile services

1)Website is build in VB.NET using Microsoft Windows Azure (server side)

2)Android Application is on Android Device (client side)

The client (Android user) should be able to send data from android device (client side) to Website (Server side) and vice-versa To make this possible ie Communcation Between client and sever I am using Mobile Services provided by Microsoft Windows Azure (server side) which use GCM (Google Cloud Messaging)

I have Followed all steps according to the documentation

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

Also followed all steps as been provided in the above link documentation of Microsoft windows azure

but when I try to send message from Android device towards the website the following error occurs

Error: com.microsoft.windowsazure.mobileservices.MobileServiceException: Error while processing request

Note: GCM (Google Cloud Messaging) gives us an gcm.jar file which is used in the android app to send data towards Server ie website

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);

        // Create an adapter to bind the items with the view
        mAdapter = new ToDoItemAdapter(this, R.layout.row_list_to_do);
        ListView listViewToDo = (ListView) findViewById(R.id.listViewToDo);
        listViewToDo.setAdapter(mAdapter);

        // Load the items from the Mobile Service
        refreshItemsFromTable();
                    }
                    catch (MalformedURLException e) {
                    createAndShowDialog(new Exception("There was an error creating the Mobile Service. Verify the URL"), "Error");
                }
                }

On BUTTON click event addItem() is called

            public void addItem(View view) {
    if (mClient == null) {
        return;
    }

    try
    {

    // Create a new item
    ToDoItem item = new ToDoItem();

    item.setText(mTextNewToDo.getText().toString());
    item.setComplete(false);

    // Insert the new item
    mToDoTable.insert(item, new TableOperationCallback<ToDoItem>() {

        public void onCompleted(ToDoItem entity, Exception exception, ServiceFilterResponse response) {

            if (exception == null) {
                if (!entity.isComplete()) {
                    mAdapter.add(entity);
                }
            } else {
                createAndShowDialog(exception, "Error");
            }

        }
    });

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

    }
}

            public void checkItem(ToDoItem item) {
    if (mClient == null) {
        return;
    }

    // Set the item as completed and update it in the table
    item.setComplete(true);

    mToDoTable.update(item, new TableOperationCallback<ToDoItem>() {

        public void onCompleted(ToDoItem entity, Exception exception, ServiceFilterResponse response) {
            if (exception == null) {
                if (entity.isComplete()) {
                    mAdapter.remove(entity);
                }
            } else {
                createAndShowDialog(exception, "Error");
            }
        }

    });
}

            private void refreshItemsFromTable() {

            } else {
                createAndShowDialog(exception, "Error");
            }
        }
    });
}


private void createAndShowDialog(Exception exception, String title) {
    createAndShowDialog(exception.toString(), title);
}

弄清楚该教程使用的是“而不是”，在我的情况下是问题所在。问题出在蔚蓝的插入脚本中。希望对您有所帮助：-)
