When you're working with native code, hardware matters. The NDK lets you ensure you're compiling for the right architectures and CPUs by giving you a variety of ABIs from which to choose.
This section begins by explaining how to target specific
architectures and CPUs. It then
provides information you need to know when targeting the
family of CPUs and architectures. Next, it provides information about the other CPUs and
architectures that it supports: NEON and x86
64-bit). Finally, it explains how to use the
library, which your app can use to query a given CPU and architecture about the optional
features they support.
