I’m guessing you’ve already requested camera permissions within the android app (and verified in OS App settings that camera is allowed)? I don’t generally have a problem with the camera at initial application launch, but I do frequently see the feed go black after an app has lost and regained focus, so there might be something funky with ARDK’s feed re-acquisition flow that shows up in a more complex app but not in a single-purpose start-tracking-on-launch demo?

The black screen issue was a known issue with 1.3.1 and has been resolved with the release of ARDK 2.0.0. Please update to the latest version here: https://lightship.dev/account/downloads.
