Some consumers of `aconfig dump` do not support multiple bugs. At the same time, we want all flags to be associated with at least one bug. Teach aconfig to require that the bug field in the flag_declaration and parsed_flag proto messages appear exactly once. This change could have been implemented as a change of `repeated` to `optional` in the proto definition. However, the chosen approach, with a runtime check, is easier to revert if we want to support multiple bugs in the future. Bug: 293156797 Test: m all_aconfig_declarations && printflags Test: atest aconfig.test aconfig.test.java aconfig.test.cpp Change-Id: Ib87dac68b392986a8daa64e56cd85477c92fbe83
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For an outdated reference on Android.mk files, see build-system.html.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.
