Eclipse/Android - If there be Weirdness, Clean First

I have no real complaints with developing for Android's in Eclipse, but every now and then I get some unexpected weirdness and forget to do a clean first before spending any more brain cells on it.  This weirdness seems to always be focused on the proper updating of the R.* values for resources, especially for bitmap and menu ID's.

So, if you're plugging along and some just-added feature is not showing up when you run it on the emulator or a device, make sure and do a clean of the project (Project-->Clean) before delving any further.
