Build fails when building Qt Multimedia tests with Qt Creator

Build fails when I try to build an auto test in QtMultimedia (test called tst_mediadevices). The error is:

D:/qt/build/androidmultimedia/tests/auto/unit/multimedia/qmediadevices/android-build --android-platform android-33 --jdk "C:/Program Files/Eclipse Adoptium/jdk-17.0.10.7-hotspot" --gradle
Cannot find application binary in build dir D:/qt/build/androidmultimedia/tests/auto/unit/multimedia/qmediadevices/android-build//libs/x86_64/libtst_qmediadevices_x86_64.so.
19:15:12: The process "D:\qt\build\dev\qtbase\bin\androiddeployqt.exe" exited with code 2.
Error while building/deploying project QtMultimedia (kit: Android Qt 6.8.0 (android) Clang x86_64)
When executing step "Build Android APK"

I also observe that D:\qt\build\androidmultimedia\tests\auto\unit\multimedia\qmediadevices\android-build\libs\x86_64 is empty.

Building tst_qmediadevices_check from command line works

Build setup:

OS: Windows 11 with dev drive mounted on D:

Qt source tree: D:\qt\qt6\

Build directory containing all builds: D:\qt\build\

Host build for dev branch: D:\qt\build\dev\

Qt Creator preparations

1. Install Qt Creator with Android option
2. In Creator preferences, install Adoptium JDK (C:\Program Files\Eclipse Adoptium\jdk-17.0.10.7-hotspot)
3. Android SDK location: C:\dev\android
4. Select Android NDK 26.1.10909125 and make default
5. Oppenssl location: C:\dev\android\android_openssl
6. Verify Android settings:

1. Add Android device for ABI x86_64, OS Version 13.0 ("Tiramisu") (SDK 33)

Building Qt:

Main build root Android: D:\qt\build\android

Configure Qt for Android in build root using host build

cmake -DQT_BUILD_SUBMODULES=QtMultimedia -DQT_HOST_PATH=D:/qt/build/dev/qtbase -DQT_BUILD_TESTS_BY_DEFAULT=OFF -DQT_BUILD_TESTS=ON -DANDROID_PLATFORM=android-33 -DQT_USE_TARGET_ANDROID_BUILD_DIR=TRUE -DQT_QMAKE_TARGET_MKSPEC=android-clang -DANDROID_SDK_ROOT=C:/dev/android -DANDROID_NDK_ROOT=C:/dev/android/ndk/26.1.10909125 -DANDROID_ABI=x86_64 -DQT_BUILD_EXAMPLES=FALSE -DCMAKE_BUILD_TYPE=Debug -DINPUT_developer_build=yes --fresh -G Ninja D:/qt/qt6 & ninja

Main build directory for Qt Multimedia on Android: D:\qt\build\androidmultimedia Configure Qt Multimedia for Android

cmake-DCMAKE_TOOLCHAIN_FILE=D:\qt\build\android\qtbase\lib\cmake\qt6\qt.toolchain.cmake -G Ninja  -DQT_USE_ORIGINAL_COMPILER=ON -DQT_BUILD_TESTS=ON -DQT_BUILD_TESTS_BY_DEFAULT=OFF D:/qt/qt6/qtmultimedia & ninja

Importing Qt Multimedia build into Qt Creator:

1. Open QtMultimedia CMakeLists.txt from D:\qt\qt6\qtmultimedia
2. Deselect all kits
3. Import build from D:\qt\build\androidmultimedia
   • This creates a Android Qt 6.8.0 (android) Clang x86_64 kit
   • Configure is run automatically again
4. Select a test to be built (tst_qmediadevices) and choose a corresponding emulator in project build settings for Android kit
5. Build target tst_qmediadevices
6. Observe error message:
