Google changes how Android stats are collected
Summary: Google changes the way it collects version information about Android, give Jelly Bean a significant usage share boost. However the aging Gingerbread continues to be the most popular version of Android.
Search giant Google has changed the way that it collects statistics on Android device usage in an attempt to give developers a better picture of the version landscape.
Google used to collect information on the versions of Android in use by keeping a tally of automated check-ins to its servers, but this month, that system has been replaced with one where only devices accessing the Google Play store are counted.
News of the change was broken on Google's Android Developer Dashboard page.
Beginning in April 2013, these charts are now built using data collected from each device when the user visits the Google Play Store. Previously, the data was collected when the device simply checked in to Google servers. We believe the new data more accurately reflects those users who are most engaged in the Android and Google Play ecosystem.
This change in how the statistics are collected has given the most current versions of Android, 4.1.x and 4.2.x, otherwise known as Jelly Bean, a significant boost, up from 16.5 percent last month to a whopping 25 percent for the 14-day period ending on April 2, 2013.

Even under this new data collection regime, the most popular version of Android continues to be Android 2.3.3 to 2.3.7 Gingerbread, a version first released back in February 2011.
So, are these numbers twisted in Google's favor, or are they a more accurate representation of the Android versions in use?
My take on this is that the data on the Android Developer Dashboard is aimed at helping developers know what versions of Android are most popular in the Google Play store so they can write apps that target these platforms, and that this data was never meant to provide a metric as to Android usage. With that in mind, restricting the data collected to devices that actually access the store gives developers a fairer view of their potential audience.
However, by hanging the way the data is collected, Google has made it harder to get a full picture on what devices are in use, and the fact that the new collection method seems to skew the data in favor of the later versions of Android will no doubt take some of the pressure off Google to do more to get Android updates into the hands of users.

Just curious wrt Android updates
Most phone models running ICS and JB don't continue to get updates.
yup
It's (almost) irrelevant
Phones have a shorter life than traditional PCs, upgrades are not that relevant as some try to make it.
Yep, and...
I agree
says the man with a new/expensive phone
Yes and No
Most vendors will push out the minor patches but, not all of them. However, you asked if they were updated for critical updates and at this point they are beyond the two year support cycle but, given the install base, I would bet really critical updates would still be rolling out.
But they don't get updated. It is that simple.
much as i'd like to agree...
The answer is neither...
From a developer stand-point, this will help make a decision on what you need to code/test for but it will show a bias toward newer devices and lower the count for old devices. It will show a slightly better picture of OS adoption but this is a side effect.
It will not give an accurate representation on Android versions in use but it will give an accurate representation of usage.
The key point, however, is this line Google:
"We believe the new data more accurately reflects those users who are most engaged in the Android and Google Play ecosystem."
Android has always had an engagement issue. It has very low engagement on web browsers and applications when compared to other smartphone platforms. This is the first time Google has actually acknowledged this.
about engagement
why do you think it's a problem?
That's not true
Android just has more advanced browsers that can report themselves as anything the user chooses. Mine right now is being reported as a desktop OS and I have the options of iPhone, iPad, Android, Desktop, or Custom (I can the web page I am on IE if I want.
As for the Play store, a large number of countries see significantly more engagement within the play store than Apple's App store and these stats are out there.
Throwing bad excuses around is simply silly
I know of no country where per capita engagement on Android is higher than either iOS or WP. There are countries with significant installed base and market share but per capita engagement is still very low.
browser stat skewed
And the zealots shout about iOS browser usage stats
are you claiming to be typical????
Correction: not most popular,
I doubt a lot of people are willingly choosing to stay on gingerbread.
gingerbread
It got a million versions of ICS from Samsung to choose from but very few carriers pushed any of them to users as an update.
frankly, they don't have a reason to update, their S2 runs fine without it.
Most normal people just don't have update-itis.
