Generate partial ota update package if the board defines it Many partners have asked for platform support of system-only update. So we config cuttlefish as an example to support the partial ota updates. Also make such package available on the build server. This allows continuous test to ensure the e2e update flow is working. Bug: 170921953 Test: generate & apply a partial update, check output in presubmit Change-Id: I79d0abeb1b2be18e6ff88f0455b6de6540a37794
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For an outdated reference on Android.mk files, see build-system.html.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.
