-*Note for the curious on JNI naming conventions: In order to reference a symbol in the JNI library you need to structure the package and class in your Android Studio project in a very particular way. For example, in the ZeroTierSDK we define a function called `Java_ZeroTier_SDK_startOneService`, the name can be broken down as follows: `Java_PACKAGENAME_CLASSNAME_startOneService`, so as we've defined it, you must create a package called `ZeroTier` and add a class called `SDK`.*
