I disagree. I don't think this is an "Android" issue, and I'm not going to get into a rant about Android versus iPhone. Both are good, and there are plenty of people that prefer one or the other.
I have about 50 apps downloaded to my Galaxy S3. Even when the phone is upgraded to a new version of Android, I've never gotten an 'incompatible' message. I don't know exactly how the Playstore determines compatibility, but it is likely a combination of acceptable Android versions and some minimum hardware requirements, rather than long lists for each app of specific handsets.
Consider the Verizon Galaxy S3. When I first checked the Playstore, it was available, meaning my device was compatible. 3 days later, my Android version was upgraded from 4.1.1 to 4.1.2, a minor version upgrade. After that, Bringgo was no longer compatible or available to be purchased through the Playstore. Same hardware, same screen size, same amount of memory.
None of my other apps stopped working because there was a minor version upgrade. My bet is that Bringgo set up specific version criteria for compatibility, including probably most Android versions from 2.3 through 4.1.1, but failed to edit that list to include 4.1.2 when it was rolled out.
By the way, these Android version upgrades aren't a surprise and don't happen overnight. I get a version upgrade to the OS about every three or four months, and their release is quite well publicized on sites like Androidcentral.com.
Engis, up until Bringgo, was purely an iPhone programmer, and only played in that sandbox with Apple 'rules', which are different than Android. If they want to play in the Android space, they just need to pay attention. I don 't think it'sthat complicated, and thousands of other developers do just fine keeping their Android apps compatible.
So I do think this is a Bringgo problem. Android is an afterthought to them, and they don't understand yet how to work in the Android space. They could easily 'release' compatibility for 4.1.2. If it crashes, then pull it back. It is a little different animal than 4.2.2, which is on the Nexus devices, which does have some major changes to the OS. But that's no different than the major version upgrades to iOs.
Very curious that Bringgo is totally silent on here. Nobody from that company is participating on here (and yes, they know about it, if not from me ---I've emailed them about it --- then they should know from Chevy.) This could be a great resource for them, but they're totally ignoring it.
