HARDWARE

he main hardware platform for Android is the ARM architecture (ARMv7 and ARMv8-A architectures; formerly also ARMv5), and MIPS^[d] architectures also officially supported in later versions of Android, but MIPS support has since been deprecated.^[241]

Unofficial Android-x86 project used to provide support for the x86 and MIPS architectures ahead of the official support.^[242][243] In 2012, Android devices with Intel processors began to appear, including phones^[244] and tablets. While gaining support for 64-bit platforms, Android was first made to run on 64-bit x86 and then on ARM64.^[245][246] Since Android 5.0 Lollipop, 64-bit variants of all platforms are supported in addition to the 32-bit variants.

Requirements for the minimum amount of RAM for devices running Android 7.1 depend on screen size and density and type of CPU, ranging from 816 MB–1.8 GB for 64-bit and 512 MB–1.3 GB for 32-bit meaning in practice 1 GB for the most common type of display (while minimum for Android watch is 416 MB).The recommendation for Android 4.4 is to have at least 512 MB of RAM,^[248] while for "low RAM" devices 340 MB is the required minimum amount that does not include memory dedicated to various hardware components such as the baseband processor.^[147] Android 4.4 requires a 32-bit ARMv7, MIPS or x86 architecture processor (latter two through unofficial ports),together with an OpenGL ES 2.0 compatible graphics processing unit (GPU).^[249] Android supports OpenGL ES 1.1, 2.0, 3.0, 3.2 and since Android 7.0 Vulkan (and version 1.1 available for some devices^[). Some applications may explicitly require a certain version of the OpenGL ES, and suitable GPU hardware is required to run such applications.

Android used to require an autofocus camera, which was relaxed to a fixed-focus camera^[251] if present at all, since the camera was dropped as a requirement entirely (except for smartphones) when Android started to be used on set-top boxes.
