You need the Android Native Development Kit (NDK) installed. See
[here](https://developer.android.com/ndk) to download it.
This project is tested against Android NDK version r21d.
This project is tested against Android NDK version r24.
If you installed version r21e all you have to do is to expose the NDK root
If you installed version r24 all you have to do is to expose the NDK root

export ANDROID_NDK_ROOT=$HOME/android-ndk-r21e
export ANDROID_NDK_ROOT=$HOME/android-ndk-r24
