[coastguard skipped] Merge sparse cherrypicks from sparse-10167124-L44700000960899180 into tm-qpr3-c-release. COASTGUARD_SKIP: I7fd3719c59d5edd3ed89deb18f6d4bf030c48790 Change-Id: I4c1c34bd892bbfa330a504d520d2460505d6a6e1
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For an outdated reference on Android.mk files, see build-system.html.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.
