Hi Developers!
Let me show you how easy it is to make an app using the Intel® XDK.
It's free! You can get it right here (http://xdk-software.intel.com/) from Intel®. And it allows HTML5 developers to create apps for a variety of mobile devices. So what you will do is get the tool, the Intel® XDK, which stands for cross-platform development kit...
Go to the projects tab, select start a new project, use App Designer...
Give it a name like "tempproject"...
Browse to where on your file system you want the project located...
and 'Create' it!
That will create some files on your file system, you'll then be able to to edit, using the Adobe Brackets* editor...
Typing "hello world" in your project...
You can then save it, and see those changes in the Emulator.
If you want to continue to make changes you can use App Designer...
Select the 'App Framework'...
... to add some drag-and-drop controls to your application...
And that's it!
Don't forget, you can do it, with the Intel XDK!
