About Icenium:

Icenium is a product from Telerik which makes cross platform mobile development simplified. Icenium enables you to use HTML5, CSS and JavaScript to develop, test, and publish applications that run natively on the Apple iOS and Google Android mobile platforms. It combines the convenience of a local coding environment with cloud-based services powered by the Apache Cordova framework. Icenium also provides the seamless creation of a backend for your apps with data storage, user management, and email and push notifications.

Icenium also comes with Visual Studio extension, so that without leaving Visual Studio you can create cross platform mobile applications. Find out more about the extension here: http://www.icenium.com/blog/icenium-team-blog/2013/09/23/announcing-the-icenium-extension-for-visual-studio

Q & A:

We had a lot of questions asked during the webinar. Our team was able to answer as much as we can during the webinar. We normally do a recap of the questions and try to provide answers to all of them through this blog post. So here are the questions from the webinar along with the answers:

Q: Are these native apps we are talking about?
A: We are talking about a model of Mobile App development called Hybrid Application Model. In this model you develop app using HTML5/JavaScript/CSS. You package this and it runs on the device pretty muck like a native app.

Q: Can we use Express Edition to practice this?
A: Sorry. This needs a non-Express VS edition

Q: Can we practice it on any other ide other than VS or is it only for it?
A: The webinar featured a extension we have for Visual Studio. But Icenium comes as a stand alone IDE also. We have Windows Client called Icenium Graphite or you can use Icenium on the browser itself. Currently supported only on Chrome.

Q: For android development with visual studio can we do it without any explicit plugin?
A: Yes. It depends mostly on your application feature and design. If you are building a simple data entry application which does not require any custom plugin you can do it easily with just a HTML markup and a JavaScript code to handle service calls.

Q: How difficult/easy it is to design my app once, and create ios application and android application PARALLELY?
A: With Icenium and Kendo UI Mobile controls, you write your code only once. Icenium lets you build packages for Android and iOS right within Icenium. Kendo UI Mobile controls provide you the adaptive rendering capability i.e. Kendo UI Mobile controls adapt to platform they are running on and give you native look and feel.

Q: what is Icenium?
A: Icenium – Mobile application development tool from Telerik. More details: http://www.icenium.com

Q: Can the jQuery version file be changed at any time?
A: Yes you can.

Q: Is Icenium different from Kendo control set ?
A: Icenium = Cloud IDE + Build Services + Simulators + Debug Capabilitie + Mobile BaaS + Kendo Mobile

Q: Will Icenium Support design and development of Web Services or the same will have to be developed seperately in .NET?
A: This will need to be developed separately. We have a Visual Studio addin avaialble to do the same called OpenAccess. http://www.telerik.com/products/orm.aspx

Q: Is Icenium an opensource?
A: No. Icenium is licensed product. It is per developer subscription based.

Q: Since iOS 7 is released, how do we set the version to 7.0 in iOS simulator?
A:. Work is under way. We will update the simulator once we are ready. In fact we already have a flat theme in Kendo UI Mobile control set from past year or so. So you already have a flat theme to apply to your apps.

Q: Which Visual Studio version we are going to discuss to achieve this?
A: Icenium Extension for Visual Studio supports only Visual Studio 2012 at the moment.

Q: Can we run tis apps on windows phone 8 also?
A: Yes. But Icenium cannot make the package for you. You will need to copy the complete source code. use Windows Phone project template for HTML5 and dump your code. Then create the XAP file and put it to market place.

Q: this will be compatible with all device of Android and iPhone?
A: Yes. Icenium also provides adaptive rendering for individual platform.

Q: Only VS 2012 is enough or do we need to install any plugins?
A: You will need to install Icenium Extension for Visual Studio from Visual Studio Gallery.

Q: From where can we download Icenium Plugin? We already have a license of telerik, do we need to buy a separate one?
A: You can download the Icenium extension from Visual Studio Gallery. You can develop an app and test in Icenium simulator. But when it comes to packaging you will need to buy Icenium subscription which is per developer and on monthly basis.

Q: Can we deploy directly to physical phone if its connected ?
