Meaning ?

How to upgrade?

@ali1377 said in menu name changing: it has been solved so please mark your post as such! Thanks

Ok, I know why it doesn't work. QtCreator 4.9 doesn't support CMake with NDK 18 and higher, 4.10 will...

Qt Firebase works good too: https://github.com/Larpon/QtFirebase

@sgaist Maybe at some point. Also, note that I am not 100% sure of what the exact instructions should be - some parts are certainly necessary, while it others might not be.

Complete Code: In the .pro: ios { OBJECTIVE_SOURCES = ios/ios_app_delegate.mm } In ios/ios_app_delegate.mm: #import "UIKit/UIKit.h" @interface QIOSApplicationDelegate @end @interface QIOSApplicationDelegate (WoboqApplicationDelegate) @end @implementation QIOSApplicationDelegate (WoboqApplicationDelegate) - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSLog(@"launch!"); return YES; } @end

Seems to be a bug reported here QTBUG-50244 Nobody tried to integrate MySQL for a Raspberry Pi project already ?! no workaround?! Seems strange :(

Hi, Because you are building your application with a Qt For Embedded Linux version and try to start it with a standard build of Qt.

Current test device is Android 9. LG V50 ThinQ

Hi @rrd0, How did you solve this problem? I am having exactly the same problem and none of the proposed solutions that I have found online are working for me

With these piece of code I have checked all the available locations: qDebug() << "Config path set to:" << configPath; for (int i = 0; i <= static_cast<int>(QStandardPaths::AppConfigLocation); i++) { const QString tmp = QStandardPaths::writableLocation(static_cast<QStandardPaths::StandardLocation>(i)); qDebug() << "Path" << i << tmp; } Seems like Qt cannot save the file where I need to: Path 0 "/data/user/0/org.qtproject.example.mri/files" Path 1 "/storage/emulated/0/Documents" Path 2 "" Path 3 "" Path 4 "/storage/emulated/0/Music" Path 5 "/storage/emulated/0/Movies" Path 6 "/storage/emulated/0/Pictures" Path 7 "/data/user/0/org.qtproject.example.mri/cache" Path 8 "/data/user/0/org.qtproject.example.mri/files" Path 9 "/data/user/0/org.qtproject.example.mri/files" Path 10 "/data/user/0/org.qtproject.example.mri/cache" Path 11 "/storage/emulated/0" Path 12 "/data/user/0/org.qtproject.example.mri/cache" Path 13 "/data/user/0/org.qtproject.example.mri/files/settings" Path 14 "/storage/emulated/0/Download" Path 15 "/data/user/0/org.qtproject.example.mri/cache" Path 16 "/data/user/0/org.qtproject.example.mri/files/settings" Path 17 "/data/user/0/org.qtproject.example.mri/files" Path 18 "/data/user/0/org.qtproject.example.mri/files/settings" Any ideas?

by "half an hour", I mean half an hour of compiling. It starts compiling qt. QtCore, QtNetwork etc. are built. Mmm, it looks too much somehow. Could you describe (processor, RAM, OS) your host PC? g++: error: /home/majid/raspi/qt5/lib/libQt5Core.so: No such file or directory In addition, could you please check entries before this one to see if you don't have any previous error, or inversely, to check that indeed such shared object file was created before reaching the point where it stops the compilation process. Yes. Shared objects are created, but not in above directory. they are created in qt source directory (e.g. QtCore is created in /home/majid/raspi/qt-everywhere-src-5.12.3/qtbase/lib/). I tested make install and I got some errors too. But some of the files get copied to qt5 and qt5pi directories as stated in configure options.

@climax You do not need separate ANDROID_PACKAGE_SOURCE_DIRs for each architecture unless you are doing something custom on the java side. The error here was in using abiFilters in the gradle file. Remove that and it works fine. You can verify by picking any android example in Qt Creator and building for both architectures.
