Mobile and Embedded

@petero3 I guess you are using Qt5 and this feature of running pipelines within multimedia module is not supported any more in Qt6. Therefore, it may be a good idea to use raw gstreamer code directly and you have much better controls over your pipelines.

I found a working way to solve the problem. https://scythe-studio.com/en/blog/how-to-interface-qt-with-android-java-code-2023 And also check. https://doc.qt.io/qt-6/qtcore-platform-androidnotifier-example.html

Thanks !
You might want to provide a minimal compilable example that reproduces this to the report.

Nevermind, turns out QFile can read the content:// URI directly.

I had the same problem. It is critical for which device you are building QT6.
In my case the EGL provider is libmali (Rockchip libMali.so). For other microcontrollers you must find some other solution.
For Rockchip apply this patch:

This code works fine for me. I am using 6.5.3.

Map { id: mapView anchors.fill: parent plugin: mapPlugin center: QtPositioning.coordinate(39.0, 32.0) zoomLevel: 25 copyrightsVisible: true //Osm [0] street activeMapType: supportedMapTypes[0] PinchHandler { id: pinch target: null onScaleChanged: (delta) => { mapView.zoomLevel += Math.log2(delta) mapView.alignCoordinateToPoint(mapView.startCentroid, pinch.centroid.position) } onRotationChanged: (delta) => { mapView.bearing -= delta mapView.alignCoordinateToPoint(mapView.startCentroid, pinch.centroid.position) } } WheelHandler { id: wheel // workaround for QTBUG-87646 / QTBUG-112394 / QTBUG-112432: // Magic Mouse pretends to be a trackpad but doesn't work with PinchHandler // and we don't yet distinguish mice and trackpads on Wayland either acceptedDevices: Qt.platform.pluginName === "cocoa" || Qt.platform.pluginName === "wayland" ?

@Sajeesh-Sathyan said in Dbus for android latest version(API:34) support:

Is D-Bus supported in the latest versions of Android?

This is rather a question for Android forum

@jsulm Yes，I am preparing to upgrade my APP to use Qt6.8. But I met the issue: https://forum.qt.io/topic/161366/qt6-8-2-qwidget-can-t-show-on-ios18-2

I had this problem in Qt6.8.2 and have this work around:

# Work around to fix build issue in Qt6.8.2 # See https://bugreports.qt.io/browse/QTBUG-131707 set(QT_NO_GLOBAL_APK_TARGET_PART_OF_ALL OFF)

Okay, so the linker error is essentially saying that it's looking for x86_64 functions but only arm64 versions exist.

@alemio Build instructions are here: https://github.com/wang-bin/QtAV/wiki/Build-QtAV
Simply use qmake from your Qt for iOS installation.

@iamnotsad Set QT_DEBUG_PLUGINS env variable to 1 in run settings before running the app and check the console output.
See https://doc.qt.io/qt-6/debug.html

Ok solved.
To enable AppLinks (in format https://your-website.com/yourcallback) besides setting up intent filters in AndroidManifest.xml you also need to configure them on google play console and deploy a json file to your website. https://developer.android.com/training/app-links#add-app-links

AFAIK, Qt would use the C++ api for that task.

Solved. There is a difference in file extensions between objective-c and objective-c++ one is *.m other is *.mm I was calling C++ from a .m file. and that caused the error.
