I'm with Jeff on this. CRM Android is for Android v4.4 (KitKat) or later. new phones are now shipping v5 (Lollipop). There was a huge amount of OS development bringing early Android into a more reasonable dev environment. My read on that industry is that we'll see less sensitivity to versions in the future.
Mobile Developers have hard choices. The easiest is to release HTML5-based apps for phones/pads. Those run on apple or Android regardless of version. BUT it doesn't produce integration with most of the messaging subsystem, so these CRM apps don't produce capture of SMS and phone. Infor CRM (SLX) took this route.
The other route is to develop specific app for Apple and/or Android devices. These are harder to develop and require much more effort just to keep running. That extra effort gets in the way of adding CRM functionality within the app. There are very few Android-only apps, and one reason that Apple has done a much, much better job of controlling version-related maintenance. As Android market share continues to rise, and as the Android OS is now much more mature, we'll see more in the Android side.
Companies using Mobile must spend a little effort over how they want to handle all this. Today, if they standardize on Apple, they don't have to worry too much about versioning, but Apple can be more expensive, and it's not obvious that Apple will still be the functionality leader 3 years from now. Way too many people have Android as personal devices, so employers can't count on that to rely on BYOD.
Android has the old-phone issues I described, so BYOD isn't good there either. (I am finally replacing my htc this week, which Android v2.3.5. This is so old, even Starbucks' app will no longer load on it ...)
If employers want to go cheap and rely on BYOD, then they can really only use HTML5 apps, which limit their functional options.
John, while I have sympathy with your situation, IMO, Sage made the best decision out of some lousy options. As consultants we need to advise our customers that the current world of Mobile apps still generally requires employers to purchase some hardware.
