The image pinned build-tools 36.0.0, whose aapt2/d8 are x86_64-only (Google publishes no arm64 Linux build-tools). Built for and run on arm64, packaging died with `aapt2: Syntax error: newline unexpected` (an x86_64 binary the kernel can't exec). Build the image for linux/amd64 on an amd64 runner, and point the template + README at ubuntu-24.04. The APK output is architecture-neutral, so this costs nothing downstream. Also execute aapt2 in the image sanity check so an arch mismatch fails the image build, not every app build. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
