NPE with "invoke virtual method"

I'm attempting a simple camera demo app. When I run takePicture, I'm getting the error below:

same error for android 8.

james-wynne-dev commented 4 years ago

I get the same issues, although I don't when I try the demo app even though I can't see any difference in the two. For me the problem seems to be around the permission. If I grant permission on the first attempt then everything is fine. If I don't, if I deny permissions on the first attempt then give permissions subsequently I get this error. There is also another plugin in my app (ML Kit) that uses the camera and this still works.

This is exactly what happens on NS7 with V5: https://github.com/NativeScript/nativescript-camera/issues/248#issuecomment-696364300
