Ah, OK. When I read the description of DroidWing I wasn't sure what the point of converting EDICT to some other format was. I will look into this further.
That's a hard copy, and an old edition at that. The digital version (which is what you need for DroidWing) is only $270[0], or free if your ethics are flexible.
Edit: Hey, the Kenkyusha dictionary is only $500 on Amazon! http://www.amazon.com/Kenkyushas-New-Japanese-English-Dictio...
