Unclear comment about an NPE that could come from an undocumented location

[LouisCAD]

Here is a problem: https://github.com/googlesamples/android-Camera2Video/blob/ac4324a4890a20b99bb7138b031e6c19cc79d190/Application/src/main/java/com/example/android/camera2video/Camera2VideoFragment.java#L457

// Currently an NPE is thrown when the Camera2API is used but not supported on the
// device this code runs.

Why would an NPE be catched there, and where would it be thrown from? This highly unclear, and borderline misleading. A clarification is needed on this point.
