Reason:
the error in tests may be the reason why Google has not updated it, so the whole system will not prompt an error during compilation. This error does not affect the subsequent use of
solutions:
error 1: isunlockingwithfacepossible() directly modifies the place where the method is called to false
error 2: the method is not rewritten ishhotspotenabling()
fakehotspotcontroller rewrites the ishhotspotenabling() method in this class

 @Override
    public boolean isHotspotEnabling() {
        return false;
    }
