I put Honeycomb on my NOOKcolor and the app market is not on it. Does anyone know how to fix it?
The nook devs site provides links and goes over downloading Google apps to your Nook color running honeycomb. Thissite lists the available Google app downloads from Cyanogenmod, explaining that they cannot come pre-installed due to licensing restrictions. The links at the very bottom of the page (and the first link) should help you find the appropriate applications.
Sometimes custom ROMs come without the Google apps (Gmail, Market, Maps, etc.) pre-loaded, in those cases it's a separate package that you need to flash over the ROM. You should check with the ROM developer where you should get the gapps from.
