In the git_main trunk stable builds, we're required to have a TARGET_RELEASE set. For now, we hard-code this to "trunk_staging" (and leave a TODO to accept this as a function argument). This will have us producing valid builds under git_main. Bug: 307975293 Test: 'tapas google-tradefed-all' now works on a tree that has go/aog/2806253 Change-Id: I70572fb4c7902350513e251694f3ddef91efcb13
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For an outdated reference on Android.mk files, see build-system.html.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.
