android - 我的应用程序不会在 Android 上使用 OpenSSL 进行链接

Question

我正在使用 david-hoze/build-openssl-android: Builds openssl 1.1.0h with android ndk r17. 在我的 Android 项目中包含 OpenSSL .

这是我的设置:安卓工作室 3.2NDK 版本:18.0.5002713

这是我应用的 build.gradle 文件:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

def my_openssl_dir = getRootDir().toString() + "/build-openssl-android/openssl-lib"

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.my-company.my-app"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        externalNativeBuild {
            cmake {
                cppFlags "-std=c++17 -frtti -fexceptions"
                arguments '-DANDROID_STL=c++_shared'
                arguments '-DMY_OPENSSL_DIR=' + my_openssl_dir
            }
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "CMakeLists.txt"
        }
    }

    sourceSets {
        main {
            jniLibs.srcDirs = [
            ]
        }

    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'org.jetbrains.kotlin:kotlin-reflect:1.2.30'
}

这是我的 CMakeLists.txt 文件:

cmake_minimum_required(VERSION 3.4.1)
include_directories( src/main/cpp/
                   )

add_library( # Sets the name of the library.
             my-library

             SHARED

             src/main/cpp/my-code.cpp
             )

find_library (log-lib log)

add_library(libcrypto STATIC IMPORTED)
set_target_properties(libcrypto PROPERTIES IMPORTED_LOCATION
${MY_OPENSSL_DIR}/${ANDROID_ABI}/libcrypto.a)

add_library(libssl STATIC IMPORTED)
set_target_properties(libssl PROPERTIES IMPORTED_LOCATION

target_include_directories(nativ PRIVATE
                       ${MY_OPENSSL_DIR}/${ANDROID_ABI}/include
                       )

target_link_libraries( # Specifies the target library.
                       my-library
                       libcrypto
                       libssl
                       ${log-lib}
                       )

我在编译时遇到了这些错误:

非常感谢您的帮助。

问题是链接顺序，我在 CMakelists.txt 文件中更改了 libssl 和 libcrypto 的顺序，如下所示:

cmake_minimum_required(VERSION 3.4.1)
include_directories( src/main/cpp/
                   )

add_library( # Sets the name of the library.
             my-library

             SHARED

             src/main/cpp/my-code.cpp
             )
