+# This file is to be used for compiling libaom for Android using the NDK.
+# In an Android project place a libaom checkout in the jni directory.
+# Run the configure script from the jni directory. Base libaom
+# encoder/decoder configuration will look similar to:
+# ./libaom/configure --target=armv7-android-gcc --disable-examples \
+# --sdk-path=/opt/android-ndk-r6b/
+#
+# When targeting Android, realtime-only is enabled by default. This can
+# be overridden by adding the command line flag:
+# --disable-realtime-only
+#
+# This will create .mk files that contain variables that contain the
+# source files to compile.
+#
+# Place an Android.mk file in the jni directory that references the
+# Android.mk file in the libaom directory:
+# LOCAL_PATH := $(call my-dir)
+# include $(CLEAR_VARS)
+# include jni/libaom/build/make/Android.mk
+#
+# There are currently two TARGET_ARCH_ABI targets for ARM.
+# armeabi and armeabi-v7a. armeabi-v7a is selected by creating an
+# Application.mk in the jni directory that contains:
+# APP_ABI := armeabi-v7a
+#
+# By default libaom will detect at runtime the existance of NEON extension.
+# For this we import the 'cpufeatures' module from the NDK sources.
+# libaom can also be configured without this runtime detection method.
+# Configuring with --disable-runtime-cpu-detect will assume presence of NEON.
+# Configuring with --disable-runtime-cpu-detect --disable-neon \
+# --disable-neon-asm
+# will remove any NEON dependency.
+
+# To change to building armeabi, run ./libaom/configure again, but with
+# --target=armv6-android-gcc and modify the Application.mk file to
+# set APP_ABI := armeabi
+#
