Intel put in a lot of legwork into ensuring that x86 is a first-class citizen on android, and this has far-reaching effects.

Beyond just building against the android runtime, it is now trivial to support additional architectures at every stage of the pipeline, even for native code.

Although x86 has the advantage that all dev workstations use it for VMs, at one point Google even had a MIPS version of the playstore, not to mention how different V7 and V8a are within ARM architectures.
