Android build failing at APK step

mzimmers

Hi all -

I've been wrestling with this issue for a few days, and I think I'm going around in circles.

I'm trying to build my app for Android. The build step seems to execute OK, but when it comes to building the APK, I get an error:

Cannot find android sources in C:/QtProjects/NgaIcdFw/appNgaIcdFw/android/src/main;C:/QtProjects/NgaIcdFw/appNgaIcdFw/android09:07:21: The process "C:\Qt\6.8.3\mingw_64\bin\androiddeployqt.exe" exited with code 11.

During cmake, android-appNgaIcdFw-deployment-settings.json is created in my build directory, and it contains the incorrect (and invalid path):

   "android-package-source-directory": "C:/QtProjects/NgaIcdFw/appNgaIcdFw/android/src/main;C:/QtProjects/NgaIcdFw/appNgaIcdFw/android",

I've tried many suggestions from ChatGPT to stop this, mostly centering around my creating my own .json file and trying to force cmake to use it with lines like this:

    # Override deployment settings used by Qt Creator
    set(QT_ANDROID_DEPLOYMENT_SETTINGS_FILE
        "${CMAKE_CURRENT_SOURCE_DIR}/appNgaIcdFw/android-deployment-settings.json"
        CACHE FILEPATH "Use maintained deployment settings file"
    )

But nothing I do prevents that file from being produced, and with a bad path.

Any idea where that bad path is coming from, and what I can do about it? Thanks...

I do not use chatgpt that much as before. If you try different chatbots(grok, deepseek), you may get different tips or solutions. Grok is supposed to be better than chatgpt as it was claimed that grok uses the most GPUs. Deepseek often gives me good code as well.

The code that creates the android-<app>-deployment-settings.json file is part of Qt6AndroidMacros.cmake found at https://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/Qt6AndroidMacros.cmake?h=6.8.3#n217

   # package source dir
    _qt_internal_add_android_deployment_property(file_contents "android-package-source-directory"
        ${target} "_qt_android_native_package_source_dir")

Which at https://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/Qt6AndroidMacros.cmake?h=6.8.3#n1018 we found out that it refers to the target property QT_ANDROID_PACKAGE_SOURCE_DIR.

QT_ANDROID_PACKAGE_SOURCE_DIR is documented at https://doc.qt.io/qt-6/cmake-target-property-qt-android-package-source-dir.html

If I look at the Dice Demo at https://code.qt.io/cgit/qt/qtdoc.git/tree/examples/demos/dice/CMakeLists.txt?h=6.8 I can see:

if(ANDROID)
    set_target_properties(${appname} PROPERTIES
        QT_ANDROID_PACKAGE_SOURCE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/android"
        QT_ANDROID_PACKAGE_NAME "io.qt.dice"
        QT_ANDROID_TARGET_SDK_VERSION 34
        QT_ANDROID_VERSION_CODE 10
        QT_ANDROID_VERSION_NAME "1.0"
    )

    qt_import_plugins(${appname}
        INCLUDE_BY_TYPE imageformats Qt::QSvgPlugin Qt::QJpegPlugin
        EXCLUDE_BY_TYPE qmltooling
        EXCLUDE_BY_TYPE iconengines
        EXCLUDE_BY_TYPE networkinformation
        EXCLUDE_BY_TYPE tls
        EXCLUDE_BY_TYPE platforminputcontexts
    )
endif()

Please do have a look at your CMakeLists.txt code which probably sets something wrong or not at all.

@cristian-adam I ended up adding this line to my cmake file:

set_property(TARGET appNgaIcdFw PROPERTY QT_ANDROID_DEPLOYMENT_SETTINGS_FILE "${CMAKE_CURRENT_BINARY_DIR}/android-appNgaIcdFw-deployment-settings.json")

Seems to have resolved this issue.
