Blame Google. Android has a craptastic audio stack and only Google can fix it.
Google would have to rip the heart out of Android and fix it for real time programming properly like OS X did way back in like 10.2?.
However, don't get me wrong, iOS isn't great--it's just at least possible. The fact that you can't actually send a defined packet (just a bag of bytes and you don't know how many until the call--"HAH! HAH! You device decided to prioritize something in the OS and your latency just quadrupled--sucks to be you.") to the Audio system on iOS is infuriating.
However, at least it's possible on iOS. On Android, not so much.

Didn't know. Looks like I'm little closer to replacing my android with iphone
Do you use your phone to create music?
Actually I was impressed with what people do in GarageBand on ios. Unfortunately I haven't found anything comparable for Android. Only ridiculous $20/month apps.
