I am trying to deploy one of my AR application on Vuzix m100 by exporting it to Android Studio and deploying from android studio to device. Everything is working fine, I am able to navigate between the button elements in UI using Vuzix's two buttons but the problem is control button of Vuzix Smart Glass is not working. I tried with the companion app of Vuzix that act as a trackpad and with that its working. I want to know what could be the problem behind this? I tried to read the code of Control Button of vuzix m100 and its "Enter" KeyCode 13 but its not allowing me select any button.
