Android Studio 编写JNI程序遇到的一些问题

1. 编译一直提示error configuration

    解决：修改build.gradle文件                

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

2. 有多个cpp文件

     复制下面代码，修改native-lib为自身cpp名称

add_library( # Sets the name of the library.
             native-lib

             # Sets the library as a shared library.
             SHARED

             # Provides a relative path to your source file(s).
             src/main/cpp/native-lib.cpp )

复制下面代码，修改native-lib为自身cpp名称

target_link_libraries( # Specifies the target library.
                       native-lib

                       # Links the target library to the log library
                       # included in the NDK.
                       ${log-lib} )

3. 设置so库生成路径

set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${PROJECT_SOURCE_DIR}/./libs/${ANDROID_ABI})

4. 更新最新版本的NDK或者Cmake

5. 查看CPP文件存储格式是否是UTF-8
