Implement BOARD_VNDK_VERSION This allows BOARD_VNDK_VERSION to be set to old versions. With VNDK snapshot and vendor snapshot installed, newer system and older vendor image can be built in the same time. Bug: 65377115 Test: 1) VNDK_SNAPSHOT_BUILD_ARTIFACTS=true m dist vndk vendor-snapshot Test: 2) install snapshot under source tree Test: 3) set BOARD_VNDK_VERSION and boot cuttlefish Change-Id: Ic5fefc8bcb866584b27f021a429cb6670a2e3048
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For an outdated reference on Android.mk files, see build-system.html.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.
