How to Use Qt6 libraries in android studio ndk?

[mesutkokalan]

I want to use Qt6 Core library in my android studio ndk project. Despite of many attempts I have failed. Please guide me how to use Qt6 libraries in android studio ndk project.

Qt6 installation directory: "C:\Qt"

And the path "C:\Qt\6.4.1" directory contains the following files and folders:

14.12.2022  18:32    <DIR>          .
14.12.2022  18:32    <DIR>          ..
10.11.2022  18:12    <DIR>          android_arm64_v8a
10.11.2022  18:16    <DIR>          android_armv7
10.11.2022  18:19    <DIR>          android_x86
10.11.2022  18:21    <DIR>          android_x86_64

10.11.2022  17:11    <DIR>          msvc2019_arm64

10.11.2022  17:47    <DIR>          Src
10.11.2022  18:25    <DIR>          wasm_32
               2 File(s)          2.084 bytes
              12 Dir(s)  230.990.303.232 bytes free

Please note that it doesn't contain CMakeLists.txt.

I tried the following steps and failed at all.

Step1:

# CMakeLists.txt
cmake_minimum_required(VERSION 3.21.1)
project(test)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

list(APPEND CMAKE_PREFIX_PATH "C:/Qt/6.4.1")
list(APPEND CMAKE_PREFIX_PATH "C:/Qt/6.4.1/mingw_64/")

find_packgggage(Qt6 REQUIRED COMPONENTS Core)

add_library(test-lib SHARED native-lib.cpp)
target_link_libraries(test-lib Qt6::Core)

Step2:

# CMakeLists.txt
cmake_minimum_required(VERSION 3.21.1)
project(test)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

add_library(test-lib SHARED native-lib.cpp)

include_directories(test-lib "C:/Qt/6.4.1/mingw_64/include")

target_link_libraries(test-lib
        "C:/Qt/6.4.1/mingw_64/lib/libQt6Core.a"
        )

All the steps above failed. How to overcome this? Any helps would be very appreciated.

Are you using Qt build for android? It is normally under android_* dir and is different from normal build.
