| # 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](Usage.txt) |
| |
| For a list of behavioral changes useful for Android.mk writers see |
| [Changes.md](Changes.md) |
| |
| For an outdated reference on Android.mk files, see |
| [build-system.html](/core/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. |
