Starting Lollipop, Android supports building binaries for two target CPU architectures, 64bit and 32bit, in the same build (known as Multilib). Amit will review Android 5.0 build configurations (32bit only, 64bit only and Multilib builds). He will then introduce Multilib builds (Primary and Secondary Zygotes), followed by how to do a Multilib build (product configuration and ARCH(s) specific Android multilib modules etc) and in the end will walkthrough couple of multilib examples from AOSP.
