+# This file is to be used for compiling libvpx for Android using the NDK.
+# In an Android project place a libvpx checkout in the jni directory.
+# Run the configure script from the jni directory.  Base libvpx
+# encoder/decoder configuration will look similar to:
+# ./libvpx/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 libvpx directory:
+# LOCAL_PATH := $(call my-dir)
+# include $(CLEAR_VARS)
+# include libvpx/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
+#
+# To change to building armeabi, run ./libvpx/configure again, but with
+# --target=arm5te-android-gcc and and modify the Application.mk file to
+# set APP_ABI := armeabi
+#
+# Running ndk-build will build libvpx and include it in your project.
