Android

4.2.2 i guess :/

Why do you ask?

Modded 2.3.6, works better than 4.0 for me

My phone was stolen, so...none.

Custom 4.3.1 Rom.

Samsung Galaxy S Advance.

4.3 on my HTC phone

4.1.1

I'm using 4.2.2.

4.4.2 Nexus 7 2013, 4.1.2 GS2

4.0.4 and happy with it :D

4.2.2 (CyanogenMod 10.1)

Samsung gt i9000

try to use api 13 or 14 for developing something they are the most common

Data, from TNG.

2.3.6 i don't want to upgrade my smartphone with cyanogen because it will eat a lot of battery

4.3

I'm using 4.2.2 on my smartphone.

After some problems I'm back to the stock rom, which is 4.1.2 right now... thinking about tryiong cyanogen again, probably 10.2 which is android 4.3

4.4.2

2.3.5

4.0.4 ics

Stock Rom 4.1.1. on my GoClever Tab R70

4.2.2, waiting for 4.4

4.3 <3

If you want statistics, here you are, those are from one of my apps:

Android 4.1 32,83%
Android 4.0.3 - 4.0.4 26,07%
Android 4.2 15,62%
Android 2.3.3 - 2.3.7 13,03%
Android 4.3 3,93%
Android 4.4 3,59%
Android 2.2 2,09%
Android 3.2 1,67%
Android 2.1 0,50%

So you can rather safely just make 4.x your requirement. In my home, we use, what, six I guess Android devices daily and all of them are 4.x.
