* Extract BUILD_NUMBER, BUILD_HOSTNAME to file to avoid kati change * Handle FILE_NAME_TAG_PLACEHOLDER string in dist in build/make/packaging/distdir.mk Ignore-AOSP-First: there are internal use cases of FILE_NAME_TAG Test: check if kati isn't invoked even though BUILD_NUMBER, BUILD_HOSTNAME is changed Test: m && m, and check if the second m is no-op Bug: 278060169 (cherry picked from https://googleplex-android-review.googlesource.com/q/commit:7b40aa8338ba85a58ee481fe6bafac2959f7112b) Merged-In: I1b37760242853c1a145bad255d0bb15524234b25 Change-Id: I1b37760242853c1a145bad255d0bb15524234b25
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For an outdated reference on Android.mk files, see build-system.html.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.
