我试图在我的android应用程序中加载OpenSSL .so文件,但它正在抛出UnsatisfiedLinkError。
MyCode:
public class MainActivity extends AppCompatActivity {
static {
System.loadLibrary("ssl");
System.loadLibrary("crypto");
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}}
例外:

CMakeList.txt
cmake_minimum_required(VERSION 3.4.1)
# configure import libs
set(distribution_DIR ${PROJECT_SOURCE_DIR}/src/main/cpp)
add_library(lib_crypto SHARED IMPORTED)
set_target_properties(lib_crypto PROPERTIES IMPORTED_LOCATION

add_library(lib_ssl SHARED IMPORTED)
set_target_properties(lib_ssl PROPERTIES IMPORTED_LOCATION

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")
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
)
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 )
target_include_directories(native-lib PRIVATE
${distribution_DIR}/include
${distribution_DIR}/include)
target_link_libraries( # Specifies the target library.
native-lib
android
lib_crypto
lib_ssl
# Links the target library to the log library
# included in the NDK.
${log-lib} )
这高于我的代码和例外。我还在CMakeList.txt中导入.SO(s),但我无法找到问题的确切问题,因为我还将.SO(s)放在了libs文件夹中。
请建议我一些解决方案。
答案
我的坏,我通过添加$ {ANDROID_ABI}来解决它,我忘了将.SO放在ABI文件夹中。
set(distribution_DIR ${PROJECT_SOURCE_DIR}/src/main/cpp/${ANDROID_ABI})
