Care maps need to store the original image size, which excludes bytes used by hash tree or FEC code. We used to propagate original image size using the global OPTIONS dictionary. This is bad coding practice, and also fragile because we have to make sure what's stored in dictionary and what's on disk are consistent. Instead, let's read the content of images on disk, and parse the AVB footer. The AVB footer contains the ground truth original image size. Test: build OTA, make sure the care maps have valid range Bug: 246504616 Change-Id: I9250b478ab34dda60578a6b8c23ae6d7a9385788 |

Android Make Build System
This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
