Hi, so the Pico Android Native SDK does not support eye tracking as confirmed by their support team and they told me to utilize the Tobii Native SDK. The official Tobii native sdk only includes windows DLLs as far as I could see, but I was able to find an Android arm64-v8a .so file for the tobii stream engine that I extracted from the TobiiXR Unity package.
In Unity this .so file is used through a C# interop setup, so would my best bet be to set up something similar in Java/Kotlin? If that would even work?
