This is the first in a series of posts that will attempt to address building mobile widgets that will scale properly between multiple devices. We will look at how we can deal with multiple screen resolutions, varying screen PPI (pixel per inch) densities, as well as gracefully switching between portrait and landscape modes.

This article is going to build on the concepts that were introduced in the “How to really cope with varying screen sizes and pixel resolutions in Vodafone Widgets”. Here we will actually build a sample widget that scales dynamically.

The Wholesale Applications Community (WAC), an alliance of telecommunications companies committed to building an open applications platform, today announced its formation as a corporate entity, as well as the organisation’s leadership and board of directors. The company also announced that it will join forces with the Joint Innovation Lab (JIL), accelerating the commercial launch of WAC-enabled application stores.

At launch, WAC will allow operators to distribute applications through their respective application storefronts and charge users through their existing phone bill.  In this model, developers will set the application price and will receive a revenue share for the transaction. The ...

The sizing of text and graphical elements on different displays is a fairly complex problem in Web development. It is different to what you simulate when you drag your browser window to different sizes – because it is more about the pixel's physical size. A working solution to this is built into the Vodafone Widget Manager and it's only based on standards: CSS, CSS Media Queries and JavaScript.

Pixel-Density

Displays have two obvious characteristics: The sheer physical size and the number of pixels they are made of, often called "resolution". However these two are actually combined into a third ...

We've been seeing a lot of widgets coming into the Vodafone 360 Shop app review queue recently that have incorrect config.xml files. Some of the widgets work OK (some of the time), but many do not. Here are some quick tips for avoiding issues now and in the future:

Tip 1

To create a valid config.xml that will work across all of our 50 widget-enabled phones, use the Vodafone Widget Packager GUI (available for Windows, Mac and Linux). If you prefer to do this by hand, follow our tutorial or refer to section two of the Compatibility ...
