First of all, I want to say nice work. The android toolchain itself seems harder to use than this.
Secondly, when I compile the basic example, when I open the app it says:
Detected problems with native app libraries
(please consult log for detail):
libentry.so: invalid DT_NEEDED entry "./obj/local/armabi/libchicken.so"
The game works fine though. I encounter this issue on my nexus 5x
