Mobile and Embedded

I'm using qsettings as ini files in that folder. Moreover I'm also storing sqlite databases and json configurations files. All of them disappeared after the update.

@kromignon Since Android is based on Linux you could put the libs in /usr/lib and see whether it works.

Androïd is a Linux based OS.

You might be able to translate the python library in something that is suitable in C/C++.

@LyzV Debug builds can be a bit bigger than Release ones ;-) You may still be a bit optimistic if you expect to "port your application from non-Qt to Qt" and not see any difference in final size.

I’m running into the same issue. I created a bug report for it, feel free to follow or vote on it: https://bugreports.qt.io/browse/QTCREATORBUG-22765

@jsulm Yes. My application is very old, but i need new Qt now. I can not change the whole application in order to use api calls right now. I know that this architecture is very painful and problematic but this is that i have for now.

@Mikeeeeee HTTPS, I guess it is an issue with OpenSSL libs

@Mohit-Tripathi said in Completion notification after completion of write the data in file through UART: How can I do this? Can you please tell me? https://doc.qt.io/qt-5/signalsandslots.html

@Mike-V AppStudio now supports DocumentDialog which lets you open pdfs on iOS.

@mrjj I already used the following code : dir_model=new QFileSystemModel(this); dir_liste=new QTreeView(this); dir_model->setRootPath(QDir::rootPath()); dir_liste->setModel(dir_model); I add permission "android.permission.READ_EXTERNAL_STORAGE" and "android.permission.WRITE_EXTERNAL_STORAGE" to the AndroidManifest.xml file. Also i add manual permission : Settings-> apps -> permissions -> storage, for my android app. When i run my app i get an empty :/ directory, with the output message : E libFileDialog.so: inotify_add_watch(/) failed: (Permission denied) How i can use QStandardpaths in my previous code ?

QAudioOutput is actually synchronous cause it blocks GUI when started. Anyway i solved the problem. i call the kill command from GUI not from thread class. it worked this way. thanks for your attention.

@Wiru Good! Than you for the advice :)

Here's a very good post about iOS "background services" https://stackoverflow.com/a/11044108

@Dipesh-Sharma Maybe https://doc.qt.io/qt-5/qdockwidget.html

Thanks a lot, that's exactly what I was looking for. Correct code is: void IosShareUtils::share(const QString &text, const QUrl &url) { NSMutableArray *sharingItems = [NSMutableArray new]; if (!text.isEmpty()) { [sharingItems addObject:text.toNSString()]; } if (url.isValid()) { [sharingItems addObject:url.toNSURL()]; } // get the main window rootViewController UIViewController *qtUIViewController = [[UIApplication sharedApplication].keyWindow rootViewController]; UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:nil]; if ( [activityController respondsToSelector:@selector(popoverPresentationController)] ) { // iOS8 activityController.popoverPresentationController.sourceView = qtUIViewController.view; } [qtUIViewController presentViewController:activityController animated:YES completion:nil]; }
