Android app on emulator can't find mono

When my app runs on the Android Emulator, it crashes just as it starts up, with the following line reported in the Dalvik Debug Monitor Server:

java.lang.UnsatisfiedLinkError:
Couldn’t load mono: findLibrary
returned null

It seems like the mono library has not been included in the package. Is this a bug or is there something I can do about it?

Don’t bother using an emulator, just use a real device.
