From e1be1aa1ec8e430bae4090192290ec0da54b027d Mon Sep 17 00:00:00 2001 From: "primiano@chromium.org" Date: Tue, 21 Oct 2014 10:20:41 +0000 Subject: [PATCH] Revert "Remove unecessary headers following NDK r10c update." This reverts r1394. Reason for the revert: r1394 is breaking compatibility with previous NDK (< r10c).
