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：

  1. LOCAL_STATIC_JAVA_AAR_LIBRARIES := demo

3、在include $(BUILD_PACKAGE)后面加入：

  1. include $(CLEAR_VARS)
  2. LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := demo:libs/demo.aar
  3. 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：

  1. LOCAL_STATIC_JAVA_LIBRARIES := \demo

3、在include $(BUILD_PACKAGE)后面加入：

  1. include $(CLEAR_VARS)
  2. LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := \demo:libs/demo.jar
  3. 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：

  1. PRODUCT_COPY_FILES +=
  2. device/qom/userdata/libs/demo1.so:system/lib/demo1.so
  3. device/qom/userdata/libs/demo2.so:system/lib/demo2.so

编译输出so文件

  1. PRODUCT_COPY_FILES += \
  2.     $(call find-copy-subdir-files,*,vendor/emdoor/apps/AgeingTest/libs/armeabi-v7a,system/priv-app/AgeingTest/lib/arm) \
  3.     $(call find-copy-subdir-files,*,vendor/emdoor/apps/FactoryTest/libs/armeabi-v7a,system/priv-app/FactoryTest/lib/arm)

下面给出一个导入aar包，jar包的完整Android.mk文件

  1. ifneq ($(TARGET_BUILD_PDK), true)
  2. LOCAL_PATH:= $(call my-dir)
  3. include $(CLEAR_VARS)
  4. LOCAL_SRC_FILES := $(call all-java-files-under, src)
  5. LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/res
  6. LOCAL_PACKAGE_NAME := DemoApp
  7. LOCAL_PRIVATE_PLATFORM_APIS := true
  8. LOCAL_CERTIFICATE := platform
  9. LOCAL_MODULE_TAGS := optional
  10. LOCAL_PRIVILEGED_MODULE := true
  11. LOCAL_USE_AAPT2 := true
  12. LOCAL_PROGUARD_ENABLED := disabled
  13. LOCAL_DEX_PREOPT := false
  14. LOCAL_STATIC_ANDROID_LIBRARIES += \
  15.     androidx.car_car \
  16.     androidx-constraintlayout_constraintlayout
  17. //定义jar包名称
  18. LOCAL_STATIC_JAVA_LIBRARIES := \demo_jar
  19. //定义aar包名称
  20. LOCAL_STATIC_JAVA_AAR_LIBRARIES := \demo_aar
  21. include $(BUILD_PACKAGE)
  22. //指定jar包目录和aar目录
  23. include $(CLEAR_VARS) 
  24. LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := \
  25.                                 demo_jar:libs/demo_jar.jar \
  26.                                 demo_aar:libs/demo_aar.aar
  27. include $(BUILD_MULTI_PREBUILT)
  28. endif

一些导入jar的例子
