@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.

@J.Hilk oh yes it is working great ; P

@X-Krys said in Cross compilation issues Qt + libmatrix_creator_hal: So it means I should use GCC 6 to match the compiler that lib has been built with ? 6 is the library version, so you should use the same major version of the stdc++ (assuming they keep binary compatibility, which I'm not sure about). Also you need to use a compiler that produces code that is binary compatible with the compiler used to build that library, unfortunately I have no clue which version is that exactly, but I really doubt it's as old as gcc 4.8.3.

Yep. I'm having trouble too. I'm documenting my frustration in this thread: https://forum.qt.io/topic/98432/analog-clock-example-build-run-on-android

So I thought I should close this one out. It turns out the issue in the title was a red herring. What happened was I had set the API level to a higher level when I built the APK to deploy to google play. The higher level was not compatible with my device. I then updated android SDK, which created a new issue that is preventing me from building. Thus I was not able to build for my API level (API level 24) and I got the device incompatible message. That said, I still have a problem that has me stumped. I've found two other threads where people have encountered the exact same problem I have and I have not seen a solution posted. I have completely re-installed SDK, NDK, JDK. I've wiped out my build config settings and my .pro.user file. I've also tried the example projects in addition to my project. I get the same error. Here are the threads describing the issue I still have: https://forum.qt.io/topic/91958/android-not-working-in-qt5-11-1/2 https://forum.qt.io/topic/91310/cant-build-qt-example-for-android/
