Make sure you copied the libs like libmedia.so down from your target 
device into the right platforms/android-* for your build setup. I am 
using NDK r6b and copied the libs into 
android-ndk-r6b/platforms/android-9 for my setup. See the link that 
Stefan sent in a recent msg for what libs you need.

I haven't successfully built with NDK r7 yet either, so I reverted to 
r6b just to keep moving.

Mark.
