Presumably a regression from bug 1509573.

(In reply to Ryan VanderMeulen [:RyanVM] from comment #1) > Presumably a regression from bug 1509573. Correct. Leaving NI, 'cuz I still need to fix it, but: This is because Bug 1509573 completely broke Android artifact builds. The offending thing is that I pushed the `android_apks` target into the `export` tier... which has special handling that I did not know about here: https://searchfox.org/mozilla-central/rev/13788edbabb04d004e4a1ceff41d4de68a8320a2/python/mozbuild/mozbuild/backend/recursivemake.py#595 That is, we never actually force the export tier in this situation. Luckily I think the way to address this is straight-forward; patch inbound.

This was fallout from Bug 1509573. That ticket pushed the Android APKs step into the export tier, where it is required; but since most things in export are only required for compilation, the target is not itself built by default, and in particular, not during an artifact build. That's not right; this fixes it.

This is looking happy on try. Waiting for build peer review. https://treeherder.mozilla.org/#/jobs?repo=try&revision=0cd83e32e55e7c860ae3309f682f2a813318adda
