Android configuration

Some additional configuration is required for Android.

First, install the latest SDK. In Android Studio, go to SDK Manager > SDK Tools and install NDK (Side by Side) (see Android Developer site).

After that, set the following environment variables:

# Export `$ANDROID_HOME` and change `{USER_NAME}` to your username
export ANDROID_HOME="/Users/{USER_NAME}/Library/Android/sdk"

# Locate which NDK version you have
ls $ANDROID_HOME/ndk # => 26.1.10909125

# Set it to your `NDK_PATH` environment variable
NDK_PATH=$ANDROID_HOME/ndk/26.1.10909125
