Fail to link to OpenSSL for Anroid

mjs225

I want to use https for a Qt Quick Andoird project in Qt6.2.3. I followed instructions in https://doc.qt.io/qt-6/android-openssl-support.html but still failed to link OpenSSL.

Here's what I did:

git clone https://github.com/KDAB/android_openssl.git
Create new QtQuick project targeting Android arm64-v8a
In CMakeLists.txt, include() the openssl project‘s CMakeLists.txt, add Qt6::Network dependency.
Write code to print the result of QSslSocket::supportsSsl()

I've also tried to link to the static library, but QSslSocket::supportsSsl() still returns false.
Link to libcrypto_1_1.so and libssl_1_1.so in android_openssl/latest/arm64/ lead to program crash on start up.

How can I link to OpenSSL? Thanks!

My CMakeLists.txt:

cmake_minimum_required(VERSION 3.16)

project(testAndroidOpenSSL VERSION 0.1 LANGUAGES CXX)

set(CMAKE_AUTOMOC ON)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(Qt6 6.2 COMPONENTS Quick Network REQUIRED)

if (ANDROID)
    include(D:/SrcProgram/android_openssl/CMakeLists.txt)
endif()

qt_add_executable(apptestAndroidOpenSSL
    main.cpp
)

qt_add_qml_module(apptestAndroidOpenSSL
    URI testAndroidOpenSSL
    VERSION 1.0
    QML_FILES main.qml 
)

set_target_properties(apptestAndroidOpenSSL PROPERTIES
    MACOSX_BUNDLE_GUI_IDENTIFIER my.example.com
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    WIN32_EXECUTABLE TRUE
)

target_compile_definitions(apptestAndroidOpenSSL
    PRIVATE $<$<OR:$<CONFIG:Debug>,$<CONFIG:RelWithDebInfo>>:QT_QML_DEBUG>)
target_link_libraries(apptestAndroidOpenSSL
    PRIVATE Qt6::Quick Qt6::Network)

Problem solved.
I find that although ANDROID_EXTRA_LIBS is set in the CMakeLists, libcrypto_1_1.so and libcrypto_1_1.so are not copied into the 'libs/arm64' directory of the Android build directory.
Maybe something got wrong in the build system. After I copy the two shared libraries and rebuild, they can be properly packed and loaded now.
