I am trying to load the SDK for Vuzix through the SDK manager in Android Studio but for some reason it will not display the downloads in 'SDK platforms' and 'SDK tools'.
In the 'SDK update sites' tab next to the Vuzix link I added there is a red exclamation point that displays " cvc-elt.1.a cannot find the declaration of element 'sdk: sdk-addon' " when hovered over.
I am new to SDK's and have no idea what to do for this error. I've downloaded the android SDK's and sources for 26,25,24, and 23 thinking it could help but the error still shows up.
