+# Android CMake toolchain file, for use with the Android NDK r5-r8
+# Requires cmake 2.6.3 or newer (2.8.5 or newer is recommended).
+# See home page: https://github.com/taka-no-me/android-cmake
+#
+# The file is mantained by the OpenCV project. The latest version can be get at
+# http://code.opencv.org/projects/opencv/repository/revisions/master/changes/android/android.toolchain.cmake
#
# Usage Linux:
-# $ export ANDROID_NDK=/<absolute path to NDK>
-# $ cmake -DCMAKE_TOOLCHAIN_FILE=<path to this file>/android.toolchain.cmake ..
-# $ make
+# $ export ANDROID_NDK=/absolute/path/to/the/android-ndk
+# $ mkdir build && cd build
+# $ cmake -DCMAKE_TOOLCHAIN_FILE=path/to/the/android.toolchain.cmake ..
+# $ make -j8
#
# Usage Linux (using standalone toolchain):
-# $ export ANDROID_NDK_TOOLCHAIN_ROOT=/<absolute path to standalone toolchain>
-# $ cmake -DCMAKE_TOOLCHAIN_FILE=<path to this file>/android.toolchain.cmake ..
-# $ make
+# $ export ANDROID_STANDALONE_TOOLCHAIN=/absolute/path/to/android-toolchain
+# $ mkdir build && cd build
+# $ cmake -DCMAKE_TOOLCHAIN_FILE=path/to/the/android.toolchain.cmake ..
+# $ make -j8
#
# Usage Windows:
# You need native port of make to build your project.
-# For example this one: http://gnuwin32.sourceforge.net/packages/make.htm
+# Android NDK r7 (or newer) already has make.exe on board.
+# For older NDK you have to install it separately.
+# For example, this one: http://gnuwin32.sourceforge.net/packages/make.htm
+#
+# $ SET ANDROID_NDK=C:\absolute\path\to\the\android-ndk
+# $ mkdir build && cd build
+# $ cmake.exe -G"MinGW Makefiles"
+# -DCMAKE_TOOLCHAIN_FILE=path\to\the\android.toolchain.cmake
+# -DCMAKE_MAKE_PROGRAM="%ANDROID_NDK%\prebuilt\windows\bin\make.exe" ..
+# $ cmake.exe --build .
+#
+#
+# Options (can be set as cmake parameters: -D<option_name>=<value>):
+# ANDROID_NDK=/opt/android-ndk - path to the NDK root.
+# Can be set as environment variable. Can be set only at first cmake run.
#
-# $ SET ANDROID_NDK=C:\<absolute path to NDK>\android-ndk-r6
-# $ cmake.exe -G"Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=<path to this file>\android.toolchain.cmake -DCMAKE_MAKE_PROGRAM=C:\<absolute path to make>\make.exe ..
-# $ C:\<absolute path to make>\make.exe
+# ANDROID_STANDALONE_TOOLCHAIN=/opt/android-toolchain - path to the
+# standalone toolchain. This option is not used if full NDK is found
+# (ignored if ANDROID_NDK is set).
+# Can be set as environment variable. Can be set only at first cmake run.
#
+# ANDROID_ABI=armeabi-v7a - specifies the target Application Binary
+# Interface (ABI). This option nearly matches to the APP_ABI variable
+# used by ndk-build tool from Android NDK.
#
-# Toolchain options (can be set as cmake parameters: -D<option_name>=<value>):
-# ANDROID_NDK=/opt/android-ndk-r6 - path to NDK root.
-# Can be set as environment variable.
+# Possible targets are:
+# "armeabi" - matches to the NDK ABI with the same name.
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+# "armeabi-v7a" - matches to the NDK ABI with the same name.
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+# "armeabi-v7a with NEON" - same as armeabi-v7a, but
+# sets NEON as floating-point unit
+# "armeabi-v7a with VFPV3" - same as armeabi-v7a, but
+# sets VFPV3 as floating-point unit (has 32 registers instead of 16).
+# "armeabi-v6 with VFP" - tuned for ARMv6 processors having VFP.
+# "x86" - matches to the NDK ABI with the same name.
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+# "mips" - matches to the NDK ABI with the same name
+# (It is not tested on real devices by the authos of this toolchain)
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
#
-# ANDROID_NDK_TOOLCHAIN_ROOT=/opt/android-toolchain - path to standalone toolchain.
-# Option is not used if full NDK is found. Can be set as environment variable.
+# ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for.
+# Option is read-only when standalone toolchain is used.
#
-# ANDROID_API_LEVEL=android-8 - level of android API to use.
-# Option is ignored when build uses stanalone toolchain.
+# ANDROID_TOOLCHAIN_NAME=arm-linux-androideabi-4.6 - the name of compiler
+# toolchain to be used. The list of possible values depends on the NDK
+# version. For NDK r8c the possible values are:
#
-# ARM_TARGET=armeabi-v7a - type of floating point support.
-# Other possible values are: "armeabi", "armeabi-v7a with NEON", "armeabi-v7a with VFPV3"

+# * x86-4.6
+# * x86-clang3.1
#
-# FORCE_ARM=false - set true to generate 32-bit ARM instructions instead of Thumb-1.
+# ANDROID_FORCE_ARM_BUILD=OFF - set ON to generate 32-bit ARM instructions
+# instead of Thumb. Is not available for "x86" (inapplicable) and
+# "armeabi-v6 with VFP" (is forced to be ON) ABIs.
#
-# NO_UNDEFINED=true - set true to show all undefined symbols will as linker errors even if they are not used.
+# ANDROID_NO_UNDEFINED=ON - set ON to show all undefined symbols as linker
+# errors even if they are not used.
#
+# ANDROID_SO_UNDEFINED=OFF - set ON to allow undefined symbols in shared
+# libraries. Automatically turned for NDK r5x and r6x due to GLESv2
+# problems.
#
-# Toolcahin will search for NDK/toolchain in following order:
-# ANDROID_NDK - cmake parameter

-# ANDROID_NDK - default location
-# ANDROID_NDK_TOOLCHAIN_ROOT - cmake parameter
-# ANDROID_NDK_TOOLCHAIN_ROOT - environment variable
-# ANDROID_NDK_TOOLCHAIN_ROOT - default location
+# LIBRARY_OUTPUT_PATH_ROOT=${CMAKE_SOURCE_DIR} - where to output binary
+# files. See additional details below.
#
+# ANDROID_SET_OBSOLETE_VARIABLES=ON - if set, then toolchain defines some
+# obsolete variables which were used by previous versions of this file for
+# backward compatibility.
+#
+# ANDROID_STL=gnustl_static - specify the runtime to use.
+#
+# Possible values are:
+# none -> Do not configure the runtime.
+# system -> Use the default minimal system C++ runtime library.
+# Implies -fno-rtti -fno-exceptions.
+# Is not available for standalone toolchain.
+# system_re -> Use the default minimal system C++ runtime library.

+#
+# ANDROID_STL_FORCE_FEATURES=ON - turn rtti and exceptions support based on

#
# What?:
-# Make sure to do the following in your scripts:
-# SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${my_cxx_flags}")
-# SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${my_cxx_flags}")
-# The flags will be prepopulated with critical flags, so don't loose them.
-#
-# ANDROID and BUILD_ANDROID will be set to true, you may test these
-# variables to make necessary changes.
-#
-# Also ARMEABI and ARMEABI_V7A will be set true, mutually exclusive. V7A is
-# for floating point. NEON option will be set true if fpu is set to neon.
-#
-# LIBRARY_OUTPUT_PATH_ROOT should be set in cache to determine where android
-# libraries will be installed.
-# default is ${CMAKE_SOURCE_DIR} , and the android libs will always be
-# under ${LIBRARY_OUTPUT_PATH_ROOT}/libs/armeabi* depending on target.
-# this will be convenient for android linking
-#
-# Base system is Linux, but you may need to change things
-# for android compatibility.
