Currently supported are the following CPU instruction sets:
armeabi-v7a -This is an ARM-based CPU instruction set that extends the standard ARM one and adds support for hardware floating-point support and multiple CPU cores.
x86 - This is an Application Binary Interface (ABI) that supports the instruction set commonly named x86 or IA-32.
x64 - This is the 64-bit version of the x86 instruction set. It supports larger amounts of virtual and physical memory than it was possible on its predecessor. It is backward compatible with 32-bit x86 code
