Use conditional class loading to only reference hasVibrator() from class that will be used on Honeycomb. You can see an example of that here:
https://github.com/commonsguy/cw-android/tree/master/Menus/ActionBarBC I have a HoneycombHelper class that uses getActionView() on MenuItem. I only reference that class when I am on Honeycomb. Older devices never load the class and therefore never get the VerifyError.
