在Android 9.0 (Pie)系统编译环境中，为apk导入第三方库如aar和jar包是必要的。对于aar包，需要在模块的libs目录存放aar文件，然后在Android.mk中指定LOCAL_STATIC_JAVA_AAR_LIBRARIES，并添加构建规则。对于jar包，同样放入libs目录，更新Android.mk，设置LOCAL_STATIC_JAVA_LIBRARIES并构建。对于so文件，直接复制到system/lib和lib64目录，或使用PRODUCT_COPY_FILES指令进行复制。

安卓开发中，有时候需要在系统环境下开发apk，导入第三方jar包或者so库。

导入aar包：

1、在模块根目录下新建文件夹libs，将需要aar包拷贝进libs.

2、在Android.mk文件加入：
LOCAL_STATIC_JAVA_AAR_LIBRARIES := demo

3、在include $(BUILD_PACKAGE)后面加入：
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := demo:libs/demo.aar
include $(BUILD_MULTI_PREBUILT)

导入jar包：

1、在模块根目录下新建文件夹libs，将需要jar包拷贝进libs.

2、在Android.mk文件加入：
LOCAL_STATIC_JAVA_LIBRARIES := \demo
3、在include $(BUILD_PACKAGE)后面加入：
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := \demo:libs/demo.jar
include $(BUILD_MULTI_PREBUILT)

导入so文件：

需要的so文件简单点的做法是将文件拷贝到system/lib下和system/lib64下面。
可以通过PRODUCT_COPY_FILES 进行拷贝：
PRODUCT_COPY_FILES +=
device/qom/userdata/libs/demo1.so:system/lib/demo1.so
device/qom/userdata/libs/demo2.so:system/lib/demo2.so

下面给出一个导入aar包，jar包的完整Android.mk文件

ifneq ($(TARGET_BUILD_PDK), true)
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/res
LOCAL_PACKAGE_NAME := DemoApp
LOCAL_PRIVATE_PLATFORM_APIS := true
LOCAL_CERTIFICATE := platform
LOCAL_MODULE_TAGS := optional
LOCAL_PRIVILEGED_MODULE := true
LOCAL_USE_AAPT2 := true
LOCAL_PROGUARD_ENABLED := disabled
LOCAL_DEX_PREOPT := false
LOCAL_STATIC_ANDROID_LIBRARIES += \
    androidx.car_car \
    androidx-constraintlayout_constraintlayout
//定义jar包名称
LOCAL_STATIC_JAVA_LIBRARIES := \demo_jar
//定义aar包名称
LOCAL_STATIC_JAVA_AAR_LIBRARIES := \demo_aar
include $(BUILD_PACKAGE)
//指定jar包目录和aar目录
include $(CLEAR_VARS) 
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := \
								demo_jar:libs/demo_jar.jar \
								demo_aar:libs/demo_aar.aar
include $(BUILD_MULTI_PREBUILT)
endif

一些导入jar的例子：

LOCAL_STATIC_ANDROID_LIBRARIES := \
    android-support-v7-recyclerview \
    android-support-v7-appcompat \
    android-support-percent \

LOCAL_STATIC_JAVA_LIBRARIES:=glidelibs\
    mediaplayer_gsonlib\
    libvlc\
    fastjsonlib\
    eventbuslib\
    fmlib\
    kwmusiclib\
    speechcontrollib\
    tingphoneopensdkbaby\
    litepal\
