kati
kati is an experimental GNU make clone.
The main goal of this tool is to speed-up incremental build of Android.
Currently, kati does not offer a faster build by itself. It instead converts
your Makefile to a ninja file.
How to use for Android
For Android-N+, ckati and ninja is used automatically. There is a prebuilt
checked in under prebuilts/build-tools that is used.
All Android's build commands (m, mmm, mmma, etc.) should just work.
How to use for Android (deprecated -- only for Android M or earlier)
Set up kati:
% cd ~/src
% git clone https://github.com/google/kati
% cd kati
% make
Build Android:
% cd <android-directory>
% source build/envsetup.sh
% lunch <your-choice>
% ~/src/kati/m2n --kati_stats
% ./ninja.sh
You need ninja in your $PATH.
More usage examples (deprecated way)
"make clean"
% ./ninja.sh -t clean
Note ./ninja.sh passes all parameters to ninja.
Build a specific target
For example, the following is equivalent to "make cts":
% ./ninja.sh cts
Or, if you know the path you want, you can do:
% ./ninja.sh out/host/linux-x86/bin/adb
