Mobile and Embedded

I set the Android Build SDK to android-28 and ran into the same issue. The test device is currently running Android 11, would that have any effect? My manifest currently looks like this in the editor: [image: c897fc3e-c8ca-4106-8c72-d5ca7c80f7e0.png] image url)

Hi, No it's not.

Thank you so much ! I am new to Qt I also tried this and I didn't now why my counter was incremented 2 times every time out ! now that you clarified that I had 2 objects everything make sense !Thank you int counter=0; void Capteur::onTimeoutfrein() { counter++; qDebug() <<"time is up"<<counter;/ if (getFrein()==0) { setFrein(1); qDebug() <<"le frein à main est levé" << getFrein(); } else {setFrein(0); qDebug() <<"le frein à main est bas" << getFrein(); } }

Hi, Aren't you missing the "?" for your Apple Maps call ?

Hi and welcome to devnet, You can install the Qt for iOS build using the online installer from the Qt Company.

@Francois-W said in eglfs_viv: Failed to open device: [ 5] _OpenDevice(1245): FATAL: Failed to open device, errno=No such file or directory Have you checked this error? What is missing? library, device, environment variable? Not that I have much experience with IMX6 devices myself, but given the error above, it looks like you have some issues with the EGLFS device, and I'd say not related to Qt framework. Have you tried running some other non-Qt application under EGLFS just to try your environment in the device?

@SGaist Yes, I checked the dmesg log The camera driver seems to be OK, and I have output the camera preview image to the touch screen. The GST command is like this:"gst-launch-1.0 -v v4l2src device=/dev/video0 ! fbdevsink" I'm confused that I started the application in the form of eglfs, or tried other platforms and development boards, and the camera program worked well. But on the 157 development board, using linuxfb, he crashed. There seems to be no problem with the camera driver and the program, but it just crashed. Now, I plan to use the GST command in a thread to achieve preview. Thank you very much！

@vipul-kumar said in IMX8: Audio through qt multimedia module not working: resolved the issue. great. Thank you for sharing and please don't forget to mark your post as solved!

As a workaround I'm making all my QDialogs fullscreen (which they are on iOS anyway): ... auto mainlayout = new QVBoxLayout(); setWindowState(Qt::WindowFullScreen); mainlayout->addStretch(1); mainlayout->addWidget(m_prompt); mainlayout->addStretch(1); ...

@Inevo Yes, you can use Python (PyQt, PySide). No, QML is not mandatory, you can use QtWidgets.

@MaikTheBike said in QTBluetooth not found ?: what the difference between Clang armeabi v8a, v7a, x86 and x86_64 is ? These are different processor architectures/instruction sets. Which you need depends on what device/emulator you're targeting. QtBluetooth is not part of Qt6.0, use Qt5 for now.

@Qt-embedded-developer You could simply use a https://doc.qt.io/qt-5/qset.html where you store already loaded directories (QString) and check it before loading new directories...

The same answer still applies. QColorDialog by default uses the system dialog. What exactly are you after ?

I'm trying to use QAudioInput and QAudioOutput with a bluetooth headset as well. My app works with QAudioOutput to the headset but wont use the bluetooth mic vie QAudioInput. Can you tell me what 'switching the device to communication mode' means? I am testing with an M98 heaset and Samsung S8 phone.

@GangsterV said in Error when using checkPermissions: For extra information, I'm using Qt 5.12.3, building on Android arm64-v8a using qmake. One other point, I've forgotten to ask: did you enable Android Extras in your PRO file (QT+= androidextras)?

@Qt-embedded-developer I'm sorry but I don't remember well... It was long time ago and I ported my app to QML since then. In QML it is much much easier to achieve such things. I tried to dig the old QtWidgets code but I've not found where it was yet.
