Question

1.我有一个现有的.so，由以下编译：

arm-linux-androideabi-g ++ * .cpp -o libshow_demo.so -fPIC -shared

2.然后我把它放到android studio3.0.1的项目文件夹中 the file structure

3.我在Android范围内编辑Gradle添加

sourceSets { 主要{ jniLibs.srcDir（['src / main / libs']）}}

4.然后我通过添加：

来编辑Cmakelists.txt

add_library( # Sets the name of the library.
         show_demo
         # Sets the library as a shared library.
         SHARED
         # Provides a relative path to your source file(s).
         IMPORTED )
set_target_properties( # Specifies the target library.
                       show_demo
                       # Specifies the parameter you want to define.
                       PROPERTIES IMPORTED_LOCATION
                       # Provides the path to the library you want to import.
                       src/main/libs/libshow_demo.so )
include_directories( show_demo/include/ )
target_link_libraries( # Specifies the target library.
                       native-lib show_demo
                       # Links the target library to the log library
                       # included in the NDK.
                       ${log-lib} )

5.AND来了这个bug。我不能做Gradle正确，它显示错误：

Error:FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:externalNativeBuildDebug'.
> Build command failed.
  Error while executing process /Users/bertie/Library/Android/sdk/cmake/3.6.4111459/bin/cmake with arguments {--build /Users/bertie/AndroidStudioProjects/Demo/app/.externalNativeBuild/cmake/debug/arm64-v8a --target native-lib}

如何在android studio中使用共享对象？努力，请告诉我该怎么做。谢谢你们：P

Answer 1

根据您的标题和说明，我知道您只想将现有的共享对象库包含到APK中

为此，只需在 src / main / jniLibs / armeabi / libDummy.so 或 src / main / jniLibs / x86 / libDummy.so 添加库，具体取决于你想要和运行的架构！适合我:)
