 Here is a guide to <a href="https://developer.android.com/ndk/guides/standalone_toolchain.html">create your Android standalone toolchains from the NDK</a>
 
-- Download the NDK r17c from here: https://developer.android.com/ndk/downloads/index.html
+- Download the NDK r18b from here: https://developer.android.com/ndk/downloads/index.html
 - Make sure you have Python 2.7 installed on your machine.
 - Generate the 32 and/or 64 toolchains by running the following commands:
 
 
-	$NDK/build/tools/make_standalone_toolchain.py --arch arm64 --install-dir $MY_TOOLCHAINS/aarch64-linux-android-ndk-r17c --stl libc++ --api 21
-	$NDK/build/tools/make_standalone_toolchain.py --arch arm --install-dir $MY_TOOLCHAINS/arm-linux-android-ndk-r17c --stl libc++ --api 21
+	$NDK/build/tools/make_standalone_toolchain.py --arch arm64 --install-dir $MY_TOOLCHAINS/aarch64-linux-android-ndk-r18b --stl libc++ --api 21
+	$NDK/build/tools/make_standalone_toolchain.py --arch arm --install-dir $MY_TOOLCHAINS/arm-linux-android-ndk-r18b --stl libc++ --api 21
 
 @attention We used to use gnustl but as of NDK r17 it is deprecated so we switched to libc++
 
 @note Make sure to add the toolchains to your PATH:
 
-	export PATH=$PATH:$MY_TOOLCHAINS/aarch64-linux-android-ndk-r17c/bin:$MY_TOOLCHAINS/arm-linux-android-ndk-r17c/bin
+	export PATH=$PATH:$MY_TOOLCHAINS/aarch64-linux-android-ndk-r18b/bin:$MY_TOOLCHAINS/arm-linux-android-ndk-r18b/bin
