I’ve run into the same issue. How can we build Android apps targeting multiple architectures, that statically link in things like libz.a, for example? I’m thinking that Build.cs is not the place to handle this, even though it does handle shared architecture-specific libs with some APL trickery. I’d appreciate any pointers on where to go from here for static libs.
Libz is just an example … I have custom .a files that need to be linked in 
Thanks!
