This struct name is fine, but make the file name match:
ax_snapshot_node_android.h

I can't give it a name that ends in _android.. otherwise it won't be included in
arc build targets.

Can't you override that global build rule with a local exception?

I thought that the build rules that exclude "_android" were just a first pass,
but I could be wrong. Seems worth looking into because there may be other
Android files we want to share with Arc.

Or, how about calling it AndroidArc, or AndroidPlatform or something
like that?
