Android has a serious "Chicken and the Egg" problem where e-commerce is concerned.
Take your android phone or tablet and go online to shop... mostly, the experience sucks.
But this has very little to do with Android, and very much to do with articles like this one that constantly reinforce the WRONG assumption that android users aren't interested in e-commerce.
It's not that we're not interested, it's that retailers can't be arsed providing us a decent mobile experience. Most mobile e-commerce sites (in my experience) kind of suck on Android. And it's really not Android's fault.
General functionality aside (which is often sub-par), they have iOS-like graphics, iOS-like navigation and UI pattern, and iOS browser optimizations. Android users are alienated and not being catered for, and until e-commerce developers start catering for Android users, we'll continue to arrive at a site, see it looks like an iOS web-app, and go back to our computers and use the full website - even the Hoyts Australia
mobile site still looks like a crappy low-res iPhone app.
The situation gets worse on tablets. Mostly "full" sites aren't being built responsively, with viewport specifiers and device agnostic layouts. Mostly their still being built for 1024x768.
We've had widescreen monitors and mobile phones as a norm for a decade and half a decade respectively, but "full" site designs are still mostly optimized for 4:3... or iPads. Go amazon.com
on a 7" tablet (55% of tablets are 7" according to IDC numbers http://www.zdnet.com/tablet-market-to-be-dominated-by-small-screens-says-idc-7000015962/
), and you either can't read anything because it's zoomed too far out to accommodate the site-width, or you zoom in and have to constantly side-scroll to see all the content.
Of course these trends aren't limited to e-commerce sites. Android devices are still second class citizens on most sites in the exact same way.
