We need to prevent vendors from using old VNDK and SystemSDK versions for newly launched device. Otherwise, deprecating old versions of the APIs would be really difficult. Specifically, it is enforced that PRODUCT_SHIPPING_API_LEVEL <= BOARD_VNDK_VERSION PRODUCT_SHIPPING_API_LEVEL <= min(BOARD_SYSTEMSDK_VERSIONS) Bug: 72126206 Test: manually setting BOARD_VNDK_VERSION to 24 in device/google/wahoo/BoardConfig.mk and choosecom to walleye Test: m -j shows an error on BOARD_VNDK_VERSION Test: BOARD_SYSTEMSDK_VERSION="25 26" m -j shows an error on BOARD_SYSTEMSDK_VERSION Change-Id: I17646487a9c77a6a5110749e22ba47f0f75920cf |

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For an outdated reference on Android.mk files, see build-system.html.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.
