the main hardware platform for android is arm (the armv7 and armv8-a architectures), with x86 and x86-64 architectures also officially supported in later versions of android. the unofficial android-x86 project provided support for x86 architectures ahead of the official support. the armv5te and mips32/64 architectures were also historically supported but removed in later android releases. since 2012, android devices with intel processors began to appear, including phones and tablets. while gaining support for 64-bit platforms, android was first made to run on 64-bit x86 and then on arm64. since android 5.0 "lollipop", 64-bit variants of all platforms are supported in addition to the 32-bit variants.
