Here is Graph of which android version is most used in today by users:

Global Android version distribution since December 2009. As of June 2015, Android 4.4 "KitKat" is the single most widely used Android version, operating on 39.2% of all Android devices accessing Google Play. The second are different Android "Jelly Bean" versions (4.1–4.3.1), with a combined share of 37.4%

Fact:

On September 3, 2013, Google announced that one billion activated Android devices were in use worldwide.In June 2015, Android devices that accessed Internet accounted for 59.1% of the worldwide smartphone and tablet market, 68.3% of the Chinese market, and 40.78% of the US market

Hardware Requirement To Run Android:

The main hardware platform for Android is the ARM architecture, with x86^[c] and MIPS^[d] architectures also officially supported. Both 64-bit and 32-bit variants of all three architectures are supported since the release of Android 5.0;^[189] unofficial Android-x86 project had provided support for the x86 and MIPS architectures ahead of the official support.^[190][191] Since 2012, Android devices with Intel processors began to appear, including phones^[192] and tablets. While gaining support for 64-bit platforms, Android was first made to run on 64-bit x86 and then on ARM64.

Minimum hardware requirements have been upgraded in steps over time, with the new Android version releases. Original minimums were 32 MB of RAM (but less than 128 MB was not recommended,^[193] with first phone HTC Dream ("flagship") phone using 192 MB), 32 MB of Flash memory, and a 200 MHz ARM architecture (ARMv5) processor. As of November 2013 and Android version 4.4, builds for ARM-based devices require an ARMv7 processor (Android 5.0 also supports ARMv8-A), while recommended minimum amount of RAM is 512 MB.The required minimum amount of RAM available to Android 4.4 is 340 MB (this amount does not include memory dedicated to various hardware components such as the baseband processor), and all devices with less than 512 MB of RAM must report themselves as "low RAM" devices.

With the release of Android 4.0 in October 2011, a graphics processing unit (GPU) supporting OpenGL ES 2.0 (and ES 1.0) hardware acceleration became mandatory, regardless of whether installed applications directly use the OpenGL ES or not. Later, Android 4.3 added support for OpenGL ES 3.0 and Android 5.0 added OpenGL ES 3.1; if used, support for both older versions (ES 2.0 and 1.0) is still mandatory.

In addition to running directly on x86-based hardware, Android can also be run on x86 architecture by using official Android emulator as part of the Android SDK, or by using third-party emulators such as BlueStacks or Andy
