After changing branches, have you removed `/node_modules` and `/platforms` before doing `tns install`? Also, which version of nativescript are you using? My working versions are: ``` nativescript: 3.1.1 node: 6.10.3...

You should try `tns install`, not `tns install android`.

These should have been resolved in the `develop` branch. Can you try that?

Don't know if this might help but vuforia seems to be still working, just not exposing the live camera feed in the backgorund.
