Failure [INSTALL_FAILED_CPU_ABI_INCOMPATIBLE] (solved)

I’m getting this error when building my android game on my device:

Failure[INSTALL_FAILED_CPU_ABI_INCOMPATIBLE]

Any ideas on how to solve it or what it is?

EDIT: While the accepted answer was technically correct, my problem was that my phone’s CPU architecture is AR Mv 6 which is no longer supported by Unity. Time to use an Emulator.

Yes, just look through the first page of Android answers:
