NDK<第十篇>：Android.mk和Android.bp对应

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。

【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))
