Android.bp文件是Android系统的一种编译配置文件,是用来代替原来的Android.mk文件的。
【1】字符串表示
mk:
chips_dir := ../../../frameworks/opt/chips/res
bp:
chips_dir = ["../../../frameworks/opt/chips/res"]
mk:
res_dirs := $(chips_dir) $(color_picker_dir) $(timezonepicker_dir) res
bp:
res_dirs = chips_dir + color_picker_dir + timezonepicker_dir + ["res"]
mk:
src_dirs := src
bp:
src_dirs = ["src"]

【5】函数宏
LOCAL_PATH := $(call my-dir):返回Android.mk 的目录
include $(call all-java-files-under,<name>):返回位于<name>目录下的所有java文件。
如果不指定<name>,怎么返回my-dir目录下所有的java文件。
include $(call all-makefiles-under,<name>):返回位于当前 <name> 路径下所有目录中的 Android.mk 文件列表。
利用此函数,可以为构建系统提供深度嵌套的源目录层次结构。
默认情况下,系统只在 Android.mk 文件所在的目录中查找文件。
LOCAL_SRC_FILES := $(call all-logtags-files-under, src):返回 src 路径下所有 logtags 格式的文件。
【6】未找到对应关系
LOCAL_LICENSE_KINDS := SPDX-license-identifier-Apache-2.0
LOCAL_LICENSE_CONDITIONS := notice
===========================================
# 开启AAPT2打包APK,AAPT是Android Asset Packaging Tool的缩写,AAPT2在AAPT的基础做了优化。
LOCAL_USE_AAPT2 := true
===========================================
# 在什么类型的版本下编译
# user/debug/eng: 指定该模块只在 user 版本下才编译(makePRODUCT-XXX-user)
# optional: 在所有版本下都会编译
LOCAL_MODULE_TAGS := optional
===========================================
引入aar:
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := contextualcards:libs/contextualcards.aar
include $(BUILD_MULTI_PREBUILT)
===========================================
# 声明 mk 要使用到的共享 JNI 库的名称
LOCAL_JNI_SHARED_LIBRARIES := libbluetooth_jni
===========================================
mk:
# 声明用到的注解器
LOCAL_ANNOTATION_PROCESSOR_CLASSES := \
androidx.room.RoomProcessor
===========================================
# protocol 相关配置
LOCAL_PROTOC_OPTIMIZE_TYPE
===========================================
Android.mk 最后一句:include $(call all-makefiles-under, $(LOCAL_PATH))
