As I'd mentioned in the reply to your DM, you have to link against
libstagefright.so, libbinder.so, libmedia.so and libutils.so in the
android-libs folder created during build or from /system/lib in your
device/emulator.

Builds for API levels 8-10 (froyo-gingerbread) should be mutually
compatible. Haven't tested with honeycomb, but you'll have to build
separately for ICS.
