Support Factory OTA for Virtual A/B devices In Factory OTA, secondary payload should be generated without virtual_ab flag set, so that update package generator generates a regular A/B OTA (with snapshot_enabled set to false), and OTA client writes system_b without snapshots. Test: apply secondary OTA Fixes: 138733621 Change-Id: I05d534a12d4a7891ce5597f3c29e55f5185e5a8d
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For an outdated reference on Android.mk files, see build-system.html.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.
