Mobile and Embedded

Looks like either UIC is not getting run or some include paths are wrong. I don't know this build system, can't help much with that. I have created this application on QT5 and yocto has QT6. Is that fine? Not necessarily. Try Qt 6 on your desktop. Usually they are mostly source-compatible but sometimes some small modifications are necessary. But Qt5-6 differences would not produce the error from make you've quoted above.

That’s a bug in the minimal backing store implementation. It’s got nothing to do with 32 bit, which just exposes the bug. Please file a ticket at https://bugreports.qt.io.

Hello, I also encountered this situation. Have you found a solution?

As an update, I installed qtcreator from the ubuntu repo (13.0.2) and it works much better. Are there config files somewhere I can diff against the previous install to better understand the original problem?

@Felix-van-de-Donk said in How to stop application from crashing at runtime: So what did you do to solve it? Removed QT beta version (6.8.0-beta 3) Removed old kits Removed Android Emulator Removed Android SDKs I installed as I'll be deploying to Android device from now (Emulator is too unreliable) Installed QT stable version (6.7.2) Ignored red crybaby messages from W ziparchive W qt.multimedia W Qt A11Y W libEGL W QtAudioDeviceManager E BufferQueueProducer Since I'm not sure how to stop them from appearing and everything seems to be working how it should

Hi, The URL looks like it's in an private area. Shouldn't it rather be https://mirrors.kernel.org/yocto-sources/git2/code.qt.io.qt.qtdeclarative.git/ ?

I had the same problem upgrading from 6.6 to 6.7, I resolved it by using the correct NDK (26.1.10909125), see https://doc.qt.io/qt-6/android-getting-started.html

Hello. I actually don't have a physical device with Android 14 to debug. So I tried with the Google emulator (Google Play Games Developer Emulator) where the error occurs when running the APP. But I tested it with a friend's cell phone with Android 14 and the APP worked. The APP opens, but an error occurs in the APP when trying to connect to the Firebird database. I'm using a lib "libfbclient.so" provided by Firebird for connection. I don't know if this lib could be the problem. Fact that it works on Android 13. But on Android 14, the connection to the database does not work. Do you recommend any emulator for Android 14? The existing emulators in Android Studio API level 34 do not work on my computer. And the Google emulator that I downloaded causes an error in the APP, but not on the physical device. So I believe that the emulator has a problem.

OK, so for Android its kinda simple, just put to main.cpp: #include <QtCore/qjniobject.h> #include <QtCore/qcoreapplication.h> #include <QtCore/private/qandroidextras_p.h> int main(int argc, char *argv[]) { ... #ifdef __ANDROID__ if (QNativeInterface::QAndroidApplication::sdkVersion() >= __ANDROID_API_T__) { const auto notificationPermission = "android.permission.POST_NOTIFICATIONS"; auto requestResult = QtAndroidPrivate::requestPermission(notificationPermission); //if (requestResult.result() != QtAndroidPrivate::Authorized) { qWarning() << "Failed to acquire permission to post notifications (required for Android 13+)"; } } #endif ... } but how to I handle same in iOS?

@piervalli said in lcurl and JSON issue: I use lcurl instead of QNAM, because I am sure that there is a single post (request to server) instead with QNAM I doubt this...

@mvuori Thanks for reply, I have tried downgraded NDK version, from 26.x to 22.x, event the 26.1.10909125 which is the same version of NDK used in the document. All of them would got compile error (may have different error messages like missing wchar.h ).

This next part is a tangent, but I mention it because you might run into this next: You may also need to use a kind of "dummy imports qml" file later, to make sure that the deployed app contains all the Qt framework QML that you expect. Example: https://github.com/219-design/qt-qml-project-template-with-ci/blob/a85e7f49a127eab/src/app/imports.qml
