In order to generate R.java of app modules, AIDEGen needs to build
the module. It might cause system.img oversized so we turn to build
the target srcjar file if it exists in module-info.json.
Build module-info.json without this change:
Build time: 1m47.227s
File size: 14,186,429 Bytes
Build module-info.json with this change:
Build time: 1m46.796s
File size: 14,614,470 Bytes
Bug: 132407603
Test: 1. m out/target/product/generic_x86_64/module-info.json
2. by grep "target/common/obj/APPS/Settings_intermediates/aapt2.srcjar"
in module-info.json.

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For an outdated reference on Android.mk files, see build-system.html.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.
