Issue Description

I want to use deeplearning4j to train nn on Android. I try to run Android-examples. And it occurs problems below.Seems some libs not found.How to integrate them?

W/System.err: Warning: Could not load Loader: java.lang.UnsatisfiedLinkError: dlopen failed: library "libjnijavacpp.so" not found

This is a known problem with beta7. Try using the snapshots: https://deeplearning4j.konduit.ai/config/config-snapshots

Thanks.I used a real cellphone and the problems disappears.Maybe it is the problem of emulators of android studio.
