## Application.mk - Android build file for Crypto++.

## Written and placed in public domain by Jeffrey Walton. This
## Android.mk is based on Alex Afanasyev (GitHub @cawka) PR #3,
## https://github.com/weidai11/cryptopp/pull/3.
##
## The Android build system is a wrapper around GNU Make and is
## documented https://developer.android.com/ndk/guides/android_mk.
## The CPU Features library provides caps and is documented at
## https://developer.android.com/ndk/guides/cpu-features.
##
## For a list of Android Platforms and API levels see
## https://developer.android.com/ndk/guides/stable_apis.
## Android 4.3 is android-18, Android 5 is android-21,
## and Android 6.0 is android-23.
##
## Android recommends c++_shared for NDK version 16.0 and
## above. Android will be removing other runtime libraries
## as early as NDK version 18. Also see
