You can't go wrong with OpenEmbedded. BitBake recipes are ideal. It doesn't really sound like you need something as full-blown as Android, but I may be wrong. You say you need app management-- it would be nice to have some more details here, e.g. will the end-user be installing and removing apps on his or her own? I ask because it sounds like it's the only feature specific to Android you would actually use. I bet maintaining a BitBake repo would work just as well in your situation, but I'm just guessing. I would take a look at the Gumstix Overo platform.
