《教我兄弟学Android逆向06 》中关于gradle3.0以上so文件生成

linghun

本人小白最近跟帖子走教程发现后面so文件生成用帖子中的方法不行已经被弃用了

根据报错：使用CMake or ndk-build

参考贴：https://www.jianshu.com/p/997ae19a5fae
工具：Android Studio3.2

一丶先通过SDKManager下载：CMake和LLDB


二丶编写build.gradle
1.在build.gradle的defaultConfig节点下加入：

       //使用Cmake工具
        externalNativeBuild{
            cmake{
                cppFlags ""
                //生成多个版本的so文件
                abiFilters "arm64-v8a", "armeabi-v7a", "x86", "x86_64"
            }
        }


2.在build.gradle的android节点下加入：



    //配置CmakeLists.txt路径
    externalNativeBuild{
        cmake{
            path "CMakeLists.txt"
        }
    }

三丶添加CMakeLists.txt文件到build.gradle文件同级目录下

CMakeLists.txt文件内容如下：
      
# For more information about using CMake with Android Studio, read the
# documentation: https://d.android.com/studio/projects/add-native-code.html


# Sets the minimum version of CMake required to build the native library.
#CMakeLists.txt
cmake_minimum_required(VERSION 3.4.1)


# Creates and names a library, sets it as either STATIC
# or SHARED, and provides the relative paths to its source code.
# You can define multiple libraries, and CMake builds them for you.
# Gradle automatically packages shared libraries with your APK.


add_library( # Sets the name of the library.
            # 设置so文件名称.
             JniTest


             # Sets the library as a shared library.
             SHARED
             # 设置这个so文件为共享.


             # Provides a relative path to your source file(s).
             # 设置这个so文件为共享.
             src/main/jni/main.c)


# Searches for a specified prebuilt library and stores the path as a
# variable. Because CMake includes system libraries in the search path by
# default, you only need to specify the name of the public NDK library
# you want to add. CMake verifies that the library exists before
# completing its build.


find_library( # Sets the name of the path variable.
              log-lib


              # Specifies the name of the NDK library that
              # you want CMake to locate.
              log )


# Specifies libraries CMake should link to your target library. You
# can link multiple libraries, such as libraries you define in this
# build script, prebuilt third-party libraries, or system libraries.


target_link_libraries( # Specifies the target library.
                       # 制定目标库.
                       JniTest


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


四丶就可以Rebuild Project

原帖中第五步 配置SO库 不用做就可以得到如下结果：

支持。其实也可以在新建项目那里直接选native项目，as会直接帮你搞好。
