1, build/core/main.mk

# Can't use first-makefiles-under here because# --mindepth=2 makes the prunes not work.subdir_makefiles := \        $(shell build/tools/findleaves.py --prune=out --prune=.repo --prune=.git $(subdirs) Android.mk)include $(subdir_makefiles)

2,

LOCAL_PACKAGE_NAME: 指定java项目的目标

LOCAL_SRC_FILES: 可以使用$(call all-java-files-under,src)查找，但是aidl文件要手动添加

3，生成的目录

build/core/envsetup.mk

TARGET_OUT_INTERMEDIATES := $(PRODUCT_OUT)/obj

TARGET_OUT_HEADERS:= $(TARGET_OUT_INTERMEDIATES)/include TARGET_OUT_INTERMEDIATE_LIBRARIES := $(TARGET_OUT_INTERMEDIATES)/lib TARGET_OUT_COMMON_INTERMEDIATES := $(TARGET_COMMON_OUT_ROOT)/obj TARGET_OUT := $(PRODUCT_OUT)/$(TARGET_COPY_OUT_SYSTEM) TARGET_OUT_EXECUTABLES:= $(TARGET_OUT)/bin TARGET_OUT_OPTIONAL_EXECUTABLES:= $(TARGET_OUT)/xbin TARGET_OUT_SHARED_LIBRARIES:= $(TARGET_OUT)/lib TARGET_OUT_JAVA_LIBRARIES:= $(TARGET_OUT)/framework TARGET_OUT_APPS:= $(TARGET_OUT)/app TARGET_OUT_KEYLAYOUT := $(TARGET_OUT)/usr/keylayout TARGET_OUT_KEYCHARS := $(TARGET_OUT)/usr/keychars TARGET_OUT_ETC := $(TARGET_OUT)/etc TARGET_OUT_NOTICE_FILES:=$(TARGET_OUT_INTERMEDIATES)/NOTICE_FILES TARGET_OUT_FAKE := $(PRODUCT_OUT)/fake_packages

4,生成最终的image

调用打包，制作image等命令
