DropBoxManager inherits from RefBase and should be managed using sp<>. Not doing so will cause it to be reported after go/aog/674370 is committed. We eventually plan to cause such uses to fail. Bug: 79434190 Test: Build and boot master Merged-In: Ibadfaac78f8c79b81a2bb0ee64972554bdec2178 Change-Id: Ibadfaac78f8c79b81a2bb0ee64972554bdec2178
