我想在我的项目中实现AE和RSA。我下载了预先构建的openssl并包含在我的项目中。在我的项目中包含openssl后,我得到如上所述的错误。我搜索了SO一些答案,提到包括set_target_properties在CMake中(U可以检查我的CMake下面),但仍然没有使用。
我的CMakeLists.txt
# 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.
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.
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 )
add_library(openssl SHARED IMPORTED)
set_target_properties (openssl PROPERTIES IMPORTED_LOCATION ${PROJECT_SOURCE_DIR}/src/main/jniLibs/${ANDROID_ABI}/lib/libcrypto.so )
# 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.
include_directories(jni/include/)
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.
native-lib
${CMAKE_CURRENT_SOURCE_DIR}/jniLibs/${ANDROID_ABI}/lib/libcrypto.a
${CMAKE_CURRENT_SOURCE_DIR}/jniLibs/${ANDROID_ABI}/lib/libssl.a
# Links the target library to the log library
# included in the NDK.
${log-lib} )

我可以猜测,您得到引用的错误是因为您没有
jniLibs/x86_64/lib/libcrypto.a
。c3frrgcw2#
这个错误发生在我身上,当升级targetSDK版本从21到27.最后的变化,这个可怕的阶段,我的生活作为一个Android程序员是这个错误:
我的应用程序使用了一个自己的.so,它使用了www.example.com的函数libcrypto.so,因此应用了myproject.so
更改新文件的旧路径,为此,您需要转到Android Studio中的External Build Files/CMakeLists.txt(如果在您的Android Studio界面中没有显示,请转到您的文件系统并在项目中搜索它,并在实现此更改后编译)。
如果不存在,则添加set_target_properties:
收件人:
现在,构建项目并运行应用程序。
相关事项:
系统.加载库(“加密”);

希望这能有所帮助!

我的解决方案是:如果项目的父文件夹有空格或文件夹名称中不支持的字符,这一切都是因为这个。
示例:C:/users/用户/桌面/Android Studio项目/应用程序文件夹更改:Android Studio项目=〉Android Studio项目
对我很有效
