I want to list the calendars enabled for Android Wear syncing in the Android Wear app's Calendar settings.
Any way to do this?
The WearableCalendarContract available on the wearable does only lists instances. The regular CalendarContract on the phone does not provide that information.
As far as I know you can create a DataItem to provide data automatic syncing between the handheld and wearable and extend WearableListenerService (for services) lets you listen for important data layer events in a service, bind service when it needs to send data items or messages.
Sync your data manually, fetch it from the provider and send it to the wearable via DataItem API. For more information about syncing data between handheld and wearable check this document: https://developer.android.com/training/wearables/data-layer/index.html

I see that bluemix has a service called Monitoring and Analytics. All I see from that service are dashboards. I am looking for the information the dashboards are providing in the form of an API. For example, if I want to be notified that my application is down or it is slow running, etc .. Is there a way for me to either receive such alerts or for an API that I can poll periodically?
thank you
The Monitoring & Analytics service does not offer an API to retrieve its collected metrics. We realize that supporting a programmatic interface would be helpful and it's in our backlog to add that capability.
However, M&A does support the other part of your question regarding alerts. There should be an Events tab in your dashboard. In the upper right corner, there's a dropdown to "Configure events policy". If you select it, you can enable Availability alerts ("Is my app down?") and/or Performance Monitoring alerts which are geared to the app's run-time type (Liberty, Node.js, etc.). In that same dropdown you can also "Configure notification". If you specify your email address in the notification dialog, you will start receiving alerts when your Bluemix application is down or running slowly.
As some background, my company is currently using an Apple Calendar server, some Exchange servers and a Google Apps subscription to provide calendaring for different parts of the organization. I've been tasked with providing free/busy access across these services while we try to take at least one of the services out of the equation.
I've attempted to use Google Interop, but it does not work with Exchange 2013 due to Microsoft eliminating Exchange Public Folder Databases in that release. I've also set up an IIS WebDAV server to attempt to share calendars, but this has shortcomings as well because only one person is able to moderate the calendar, and f/b data can't be queried in the Apple Calendar app - you have to subscribe to a separate f/b calendar.
Are there any suggestions as to how I should proceed?
If you can write your own connectors for each service (ie using propietary API's) you could then expose that information through a custom caldav service.
For example you could use http://milton.io (java) or http://sabre.io/ (php), both allow pulling data from arbitrary data sources.
I am developing an mobile application which can be run on mobile devices (with OS like Android, iOS, WP7...). This application will get data from online database then store them to local database in device and I can do CRUD with data. There are three ideas:
I'll create a webservice to handle with database on host and use some cross-platform framework to building an app then connect to webservice in order to get and put data to server. Issues:
Which technology should I use to create webservice? (RESTful/SOAP...?)
Which type of return data for easy to handle? (XML/JSON...?)
How to sync between local database and database on host?
I'll make an application for loading an external URL and build a website (with all of features that I need to work with database). Issues:
iOS, Android, WP7... accept for loading external URL in applications?
How to sync data like my first idea?
Should I use single page application technology?
I'll make an application using cross-platform framework and it will work with local database. I just handle syncing between local database and host database. Issue: which is the best database and best framework to do this?
Thank you
How to sync between local database and database on host?
For synchronization, you can take a look at the open source project, OpenMobster's Sync service. You can do all types of sync operations
two-way
one-way client
one-way device
bootup.
Besides that, all modifications are automatically tracked and synced with the Cloud. You can have your app offline when network connection is down. It will track any changes and automatically in the background synchronize it with the cloud when the connection returns. Also, when new data is created in the Cloud, it is automatically synchronized with the local database using Push notifications.
Currently only native development is supported on Android and iOS. However, the next release which is 2.2-M8 (end of March) will support end-to-end integration with PhoneGap on Android and 2.2-M9 (end of April) will add iOS.
Support for PhoneGap will give you the flexibility to build the app using web technologies like HTML5, and JavaScript along with Sync for your local data using OpenMobster.
If you want to go pure native, then you still can use the Sync service and synchronize your local database with your remote database.
Let me know if you have more questions about the framework
Here is a link to the open source project: http://openmobster.googlecode.com
Good Luck!!!
Some suggestions:
If you're planning that your mobile application exchanges data with a server, i strongly suggest you to use RESTful Services. The XML overload associated with SOAP services might get your phone and your network into trouble
The return data can be either JSON or XML. For example, in Blackberry applications i prefer XML because the support included in the SDK.
There are three kinds of mobile applications: Web applications (build with HTML/Javascript and accessed throw a Browser), Native applications (installed in the device and coded in Java/Objective-C or another language) and Hybrid applications (installed in the device but coded in HTML/Javascript and can access some features of the OS). Your URL-Loading type sounds like an Hybrid approach (not quite sure about that), so you can use PhoneGap to build that type of applications.
Hybrid and Web applications uses the capabilities of the phone browser to manage HTML/JavaScript. Now the devices come with very powefull WebKIt-based Browsers, so the single page pattern would work with no problem. Although, it's kind of a wear approach to mobile application design.
I don't see the need of a local database in your app, you can simply handle all the data in the server and access it through RESTful Services on the phone.

Nice!!!
Which technology should I use to create webservice? (RESTful/SOAP...?)
I Will go For REST services.
REST has advantages when:
You have a set of resources that you want to manipulate.
You want to support navigation between resources.
You need scalability.
SOAP has advantages when:
You want to publish a web service description (using WSDL).
WSDL 2 can describe RESTful web service as well. WADL is an alternative to WSDL for RESTful web services.
You want to use security etc. that relies on the use of SOAP headers or some similar mechanism in which data is added and removed from a request.
You want better tooling support.
You want tested platform interoperability.
Which type of return data for easy to handle? (XML/JSON...?)
I personally go for XML
Its not a criteria of which is easy to handle.Its about performance in Mobile applications.
JSON is generally smaller than a XML document and there for faster to work with.JSON can be parsed more efficiently because it can be parsed as JavaScript, which the built-in eval() function will do for you.
How to sync between local database and database on host?
Create a service which contains a timer and runs in background.Call the REST service at intervals to get the latest values. But Since this is a polling kind of thing,then it is not efficient and has less performance. Other Approach will be use of PUSH notifications.As soon as there is any change at the server side, send a push notification to the client(mobile) and hence perform the local database operations.
iOS, Android, WP7... accept for loading external URL in applications?
I didn't understand this point.What you want actually?
Should I use single page application technology?
Single page technology is very good.But it will depend on your business.If it is possible then use it.Else create different HTML pages.
I'll make an application using cross-platform framework and it will work with local database. I just handle syncing between local database and host database. Issue: which is the best database and best framework to do this?
Choosing of the database will depend upon choosing of the cross platform mobile framework.Phonegap is exactly what you need. And the database will be sqlite. Phonegap provide API's for storage,so you can easily access the database of the different mobile platform.
I need to make a couple of mobile applications which will all access a shared online resource using e.g. REST API.
What is the cheapest/easiest setup for the server side resource?
The server should store data as either xml/json/sqlite and expose an API to access this data, preferably in a secure manner.
Is Google App Engine appropriate? Any others?
What would be a recommended way to implement?
What I want to do is to have a database online (not important which format - content will not bee too big, ~5000 records with around 5-10 text fields each), have a simple management console for editing this content and then let mobile devices connect in order to check if they have the latest data and update if required.
The data should not be publicly available but key may be hardcoded into device applications.
I want to write GAE based application that synchronizes information between computers/phones. Right now I am only querying periodically, which causes delays or requires user to click a button to refresh manually.
With GAE channels, it should be possible to do it this way that a device can be notified when it should refresh. However, since I want it to be a desktop app (not web app), I am wondering if I can write my own client to channel API? Or grab whatever's out there.
Is the protocol documented or are there clients available for anything other than JS?
The only official interface is the Javascript client library. Although you could reverse-engineer how it works, since it's not a documented part of the interface, it could change at any time without notice.
If you're interfacing with Android phones or iPhones, each of them has a 'push' messaging API that you could use (Cloud to Device Messaging for Android, and Push Messaging for iPhone).
There is now a Java implementation for the Channels API. It was just released days ago and is available via git at https://github.com/gvsumasl/jacc. I've also taken the liberty of forking it and providing a mavenized version at https://github.com/hatboyzero/jacc.
