Android loading plugin "dlopen failed: "

[Kofr]

I am trying to add MapLibre to the Qt 6.6.1 Android project. Android can not dlopen plugin during the app launch.

W ru.ubego.debug: Accessing hidden method Landroid/graphics/drawable/StateListDrawable;->getStateCount()I (light greylist, linking)

what I add to qmake

INCLUDEPATH *= \
        $$top_build_dir/libs/$${ARCH}/maplibre_native_qt_libsrc/core/include/ \

LIBS *= $$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib//install/lib/libQMapLibre_$${ARCH}.so \
$$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/lib/libQMapLibreLocation_$${ARCH}.so \
$$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/plugins/geoservices/libplugins_geoservices_qtgeoservices_maplibre_$${ARCH}.so \

ANDROID_EXTRA_LIBS +=  $$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/lib/libQMapLibre_$${ARCH}.so \
$$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/lib/libQMapLibreLocation_$${ARCH}.so \


ANDROID_EXTRA_PLUGINS += $$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/plugins \

So, I add libs to LIBS and ANDROID_EXTRA_LIBS. I add directory with the plugin itself to ANDROID_EXTRA_PLUGINS.
Does anybody have ideas?

@Kofr add $$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/plugins/geoservices/libplugins_geoservices_qtgeoservices_maplibre_$${ARCH}.so
to ANDROID_EXTRA_LIBS as well. This is not a Qt plugin, but an extra one.

ANDROID_EXTRA_LIBS +=  $$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/lib/libQMapLibre_$${ARCH}.so \
$$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/lib/libQMapLibreLocation_$${ARCH}.so \
$$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/plugins/geoservices/libplugins_geoservices_qtgeoservices_maplibre_$${ARCH}.so \

All Qt libs and plugins needed for Android will be wrapped automatically. All your own and third party libs and plugins have to be added to ANDROID_EXTRA_LIBS for deployment.

The only thisng bothers me is why dlopen tryies to open the plugin with the linux host path.
dlopen failed: library "/home/dev/dev/prj/ubego-mobile-app/build-ubego-Android_Qt_6_6_1_Clang_arm64_v8a-Debug/libs/arm64-v8a/maplibre_native_qt_lib/install/plugins/geoservices
when the starts on the Android device

@Kofr add $$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/plugins/geoservices/libplugins_geoservices_qtgeoservices_maplibre_$${ARCH}.so
to ANDROID_EXTRA_LIBS as well. This is not a Qt plugin, but an extra one.

ANDROID_EXTRA_LIBS +=  $$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/lib/libQMapLibre_$${ARCH}.so \
$$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/lib/libQMapLibreLocation_$${ARCH}.so \
$$top_build_dir/libs/$${ARCH}/maplibre_native_qt_lib/install/plugins/geoservices/libplugins_geoservices_qtgeoservices_maplibre_$${ARCH}.so \

@JoeCFD Thank you for reply. It works.
However during the startup QML can not resolve
: qrc:/XPage.qml:4 module "QtLocation.MapLibre" is not installed

on desktop it worked when I add a path to the plugin to library path, QCoreApplication::addLibraryPath("/home/prj/maplibre-native-qt/install/plugins/");
but how it works on Android?
Documentation is poor about this.

@Kofr Plugins are .so libs as well. Simply add all needed ones to your build in the same way. They are extra libs too.
