本文主要是介绍Android.mk,安卓系统AOSP源码，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
学习Android.mk可以参考安卓系统源码当中的一些mk文件
例如，build/core目录下的base_rules.mk和config.mk
base_rules.mk

# The build system exposes several variables for where to find the kernel
# headers:
# TARGET_DEVICE_KERNEL_HEADERS is automatically created for the current
# device being built. It is set as $(TARGET_DEVICE_DIR)/kernel-headers,
# e.g. device/samsung/tuna/kernel-headers. This directory is not
# explicitly set by anyone, the build system always adds this subdir.
#
# TARGET_BOARD_KERNEL_HEADERS is specified by the BoardConfig.mk file
# to allow other directories to be included. This is useful if there's
# some common place where a few headers are being kept for a group
# of devices. For example, device/<vendor>/common/kernel-headers could
# contain some headers for several of <vendor>'s devices.
#
# TARGET_PRODUCT_KERNEL_HEADERS is generated by the product inheritance
# graph. This allows architecture products to provide headers for the
# devices using that architecture. For example,
# hardware/ti/omap4xxx/omap4.mk will specify
# PRODUCT_VENDOR_KERNEL_HEADERS variable that specify where the omap4
# specific headers are, e.g. hardware/ti/omap4xxx/kernel-headers.
# The build system then combines all the values specified by all the
# PRODUCT_VENDOR_KERNEL_HEADERS directives in the product inheritance
# tree and then exports a TARGET_PRODUCT_KERNEL_HEADERS variable.
#
# The layout of subdirs in any of the kernel-headers dir should mirror the
# layout of the kernel include/ directory. For example,
# device/samsung/tuna/kernel-headers/linux/,
# hardware/ti/omap4xxx/kernel-headers/media/,
# etc.
#
# NOTE: These directories MUST contain post-processed headers using the
# bionic/libc/kernel/clean_header.py tool. Additionally, the original kernel
# headers must also be checked in, but in a different subdirectory. By
# convention, the originals should be checked into original-kernel-headers
# directory of the same parent dir. For example,
# device/samsung/tuna/kernel-headers <----- post-processed
# device/samsung/tuna/original-kernel-headers <----- originals
