Mark many single value variables as such This changes these variables to not inherit multiple values, which allow for some more flexibility in how/where they're defined in makefiles. Also remove the previous equivalent solution that was in place for the PRODUCT_BUILD_* flags. Bug: 116769560 Test: presubmit Change-Id: Ia27a11d95263ceb45ffa355e75bb2aa6d9672139
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For an outdated reference on Android.mk files, see build-system.html.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.
