  Message : Use ANGLE's vulkan-headers dep when rolling ANGLE into Android. We previously used the existing Android target for vulkan headers but it does not roll as fast as ANGLE's, possibly causing divergence in test results. BUG=angleproject:2344 BUG=b:150892231 Change-Id: Ibef33b266943c040219529f64ea8cd29c8c9bf83 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2090394 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Tim Van Patten <timvp@google.com> Commit-Queue: Geoff Lang <geofflang@chromium.org>
