YouTube 2.3.4: I used your trick and moved it from my phone to the Fire after creating an APK via ES File explorer.

ColorDict: Same as above. BTW: ColorDict works with several of the 3rd party reader apps like Mantano, so it is a very useful app. It works standalone too.
EDIT: In order to get the WordNet 3.0 dictionary data to work with ColorDict, I copied the
dictdata/dict folder from my phone to my Fire. It works!
