Add global checknotnull.flags Proguard config This config is conditionally used based on the build flag, allowing `-convertchecknotnull` R8 optimizations for a class of common null checks. Bug: 280633711 Test: build-flag set RELEASE_R8_GLOBAL_CHECK_NOT_NULL_FLAGS && m Flag: RELEASE_R8_GLOBAL_CHECK_NOT_NULL_FLAGS Change-Id: If17e7fc2c5b3306f4abaa28f310b3260c6d6294a
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For an outdated reference on Android.mk files, see build-system.html.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.
