Hello Mike,

I don't think I'll be of much help - I don't have any Android
experience. But maybe this guide has the necessary details you are
looking for
https://developer.android.com/distribute/best-practices/develop/64-bit

As noted in that guide, if your application is Java based, you won't
have to code or build it differently, it should just work fine on 64 bit
systems.

After several days my colleague and I have been able to get it to build from the command line directly with Ant and through IntelliJ (Android Studio and Eclipse both fail). The build we get is 32-bit only and we have spent close to a week trying to find what needs to be adjusted to create a 64-bit build.
