Hi and welcome to devnet, I would check with the board documentation whether there's some mirroring that could be implemented at the lowest level.

@Pradeep-P-N Since Android 6.0: https://developer.android.com/about/versions/marshmallow/android-6.0-changes#behavior-hardware-id To provide users with greater data protection, starting in this release, Android removes programmatic access to the device’s local hardware identifier for apps using the Wi-Fi and Bluetooth APIs. The WifiInfo.getMacAddress() and the BluetoothAdapter.getAddress() methods now return a constant value of 02:00:00:00:00:00. To access the hardware identifiers of nearby external devices via Bluetooth and Wi-Fi scans, your app must now have the ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permissions: WifiManager.getScanResults() BluetoothDevice.ACTION_FOUND BluetoothLeScanner.startScan() Note: When a device running Android 6.0 (API level 23) initiates a background Wi-Fi or Bluetooth scan, the operation is visible to external devices as originating from a randomized MAC address. I recommend you use Java (JNI) to get the WiFi MAC Address. (Add android.permission.ACCESS_WIFI_STATE permission) WifiManager manager = (WifiManager) getSystemService(Context.WIFI_SERVICE); WifiInfo info = manager.getConnectionInfo(); String address = info.getMacAddress(); Note: some Android devices also have a wired network connection (mostly Android TV devices though)

Do you have Qt's EGLFS platform plugin compiled and working? Do you have OpenGL drivers installed via raspi-config?

@jsulm yes thnks i cleared the combo box before navigating to that page its ok now

@morte ApplicationWindow { Item { id: banner x: 0; y: 0 width: parent width; height: 50 } Item { id: content width: parent.width anchors { top: banner.bottom bottom: parent.bottom } } }

@J.Hilk Here is that output: 09:30:03: Running steps for project hellotr... 09:30:03: Configuration unchanged, skipping qmake step. 09:30:03: Starting: "C:\Android\ndk-bundle\prebuilt\windows-x86_64\bin\make.exe" -j4 make: Nothing to be done for `first'. 09:30:04: The process "C:\Android\ndk-bundle\prebuilt\windows-x86_64\bin\make.exe" exited normally. 09:30:04: Starting: "C:\Android\ndk-bundle\prebuilt\windows-x86_64\bin\make.exe" "INSTALL_ROOT=C:/Qt/Examples/Qt-5.12.0/linguist/build-hellotr-Android_for_armeabi_v7a_Clang_Qt_5_12_0_for_Android_ARMv7-Debug/android-build" install C:\Android\ndk-bundle\prebuilt\windows-x86_64\bin\make.exe: Interrupt/Exception caught (code = 0xc00000fd, addr = 0000000000420466) 09:30:06: The process "C:\Android\ndk-bundle\prebuilt\windows-x86_64\bin\make.exe" exited with code 255.

@koahnig So there's config and rebuild needed. Thank you very much for the helpful reply.

@jsulm sadly, that didn't work for me either.

There is a Bug filed called "Can't debug Android App": https://bugreports.qt.io/browse/QTCREATORBUG-20379 In one of the comments someone mentions that you'll need to manually update the AndroidManifest.xml file to add the attribute android:debuggable="true" To the Application tag. This gets the Application deployed and starts it up. But looks like the debugger still can't attach. And it also looks like the Manifest gets autogenerated and needs to be updated each time you try to debug. Hopefully there is something one can set to adjust the automatic generation so you don't have to edit that manifest each time you need to deploy.

EDIT: I noticed something (probably) quite important. If I build my UI so that it is not embraced by a vertical layout, then the QLabels will be displayed correctly. But if I build them up so that all elements are spanned by a vertical layout, then there is the rendering problem (as described above). This extremely strange behavior is comprehensible and man can be switched back and forth: with QVBoxLayout-> display error, without QVBoxLayout-> no errors, and so on ... Here you can see the UI-Code without vertical layout around the UI-elements: [?xml version="1.0" encoding="UTF-8"?] [ui version="4.0"] [class]PrjNameMeldung1_5[/class] [widget class="QMainWindow"

@Sungyong I was stuck like you and finally found a workaround like this: Install "Android armV7" and "x86" with Qt MaintenanceTool (under Qt X version). Now you will see the two kits added to QtCreator. I selected armV7 and build went fine.

@Pablo-J-Rogina I've try to do this: Camera { id: camera viewfinder.resolution: "640x480" imageProcessing.whiteBalanceMode: CameraImageProcessing.WhiteBalanceFlash flash.mode: Camera.FlashTorch and i create a function for force the flash on function flash_start() { camera.unlock() camera.flash.mode = Camera.FlashOn camera.flash.mode = Camera.FlashTorch } But nothing works.
