[Interest] How does Google Play validates Android binaries?
Hi, I’m having a serious issue with Android deployment and this is something recent. I’m starting to think that this was not happening on previous versions of Qt. I’m currently using Qt 5.4.2 and when I deploy to Google Play, on some devices the app is not compatible (the pattern seems to be high resolution devices). On my app manifest min SDK is 14 and target SDK is 21. I also have a support-screens directive with the following: supports-screens android:smallScreens=false android:normalScreens=true android:largeScreens=true android:xlargeScreens=true/ The most awkward issue here is that a couple of months ago, the same app was available to the same device and now it isn’t. There are some possibilities in my list: - Google Play bug - Android build tools incompatibility - Qt behaviour change on androiddeployqt However I’m completely in the dark. I’m tired of making experimental builds and uploads with no positive results. Does any one knows how does Google Play analyses APK’s in order to determine if they are OK or not? The only thing Google tells me is: unsupported native platform: armeabi, armeabi-v7a” However, APK’s were built for armeabi-v7a and x86, with a superior version number for x86. The .apk works on development but isn’t allowed thru Google Play. Is anyone here experiencing the same problem? Thanks in advance!

[Interest] QThread sleep on QMutex
Hi, I hope that in this list I will find experts of synchronization and so on. My question: is it good to make thread's sleep on mutex like this? QMutex mutex; mutex.lock(); mutex.tryLock( int msecs ); // This will make sleep for the given timeout. Or it's not so good idea because thread will not release processor... Or processor will be released? Or something else? Thank you. -- Best Regards, Igor Mironchik. ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

[Interest] [ Android ] Creating task that runs in background when app not in foreground or device sleeping?
My Qt widget app has Bluetooth connection that broadcasts GPS NMEA data to a connected device. How can I maintain this connection streaming GPS data when app is not in foreground or device is in sleep? Is it even possible to run Qt C++ code on Android in the background?

[Interest] QtLocation Map Widget
Hi, I asked to the folk want they to have GeoMap widget or not. And people answered in most cases that they would like to have such widget. I didn't ask why, the reasons may vary. But... I've looked into the code of new QtLocation module and it's QML components and I came to the conclusion that it's not very difficult to implement such widget and all another stuff to show map and items on the map as Qt widget. But... I found that such implementation will be tied to the private QtLocation headers. I wanted to implement GeoMap and Items as part of the QtMWidgets library. But... I don't want to tie on the private Qt's headers in this library. So I can't to implement GeoMap right now. And I don't know what to do. I want to ask you, folk, and Qt developers. * Is it possible to open QtLocation C++ stuff, I mean headers, for example, of QGeoMappingManager? * Is it possible to implement GeoMap widget in Qt internally and allow to choose between QML and Widgets? * Is this list good to ask such questions, or better to ask in developer's list, and is it ok to ask in developer's list such questions. Thank you. -- Best Regards, Igor Mironchik. ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

Hi Igor, I've looked into the code of new QtLocation module and it's QML components and I came to the conclusion that it's not very difficult to implement such widget and all another stuff to show map and items on the map as Qt widget. But... Michal even started work on it: https://codereview.qt-project.org/#/c/115647/ but other things like bugs prevented this work form continuing.

And I don't know what to do. * Is it possible to open QtLocation C++ stuff, I mean headers, for example, of QGeoMappingManager? With the recent reactivation of QtLocation development there have been a lot changes in the private headers. Until those headers settle down we won't make them public. A public header that changes is of no use to you either. * Is it possible to implement GeoMap widget in Qt internally and allow to choose between QML and Widgets? That's definitely possible and contributions are welcome. THis has the side benefit that (once it is in) it becaomes part of the maintained offering and private header changes will have to be accompanied by similar fixes to this new QGeoMap widget. * Is this list good to ask such questions, or better to ask in developer's list, and is it ok to ask in developer's list such questions. If this becomes an effort to add the widget to the QtLocation library then the dev list is more appropriate. However I would expect that the discussion would move to gerrit fairly soon after though. -- Alex ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] QtLocation Map Widget
But I have one question: new QGeoMapWidget will be based on the QOpenGLWidget and is it possible to use such widget on mobile platforms? I heard that on mobile platforms only one OpenGL context can be used... It is far too early to know what we'll end up doing. This was mostly a proof of concept to learn what we have to change in our private and public APIs to make it work. As mentioned earlier, currently we focus on bug fixing and stabilizing the API. That's why a contribution from your side to continue this work would speed this up to maybe Qt 5.6 ? -- Alex ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

Re: [Interest] qmake Library VERSION issues on Windows
Thanks Thiago, I was afraid of that. For now I have the following in my project file: win32:unset(VERSION) Just out of curiosity: How does the Linux side know which version to link to, I am assuming this is then a feature of gcc/make and not qmake? I can't see that my dependent lib knows the version of the base lib because the VERSION variable is set in the PRO file, but my dependent lib links against the PRI file that does not contain this information. It is then probably because I normally build them together? If it is not qmake related then I understand if you do not have more information on this.

[Interest] Qt 5.5 + XCode 7 beta + IOS 8.4
Hi list. I installed XCode 7 (beta) alongside with XCode 6 and I was giving a shot to Qt 5.4 for iOS using it because it allows developing without purchasing any Apple Developer Program thing. From within XCode 7 (beta) I can run any of the sample programs it comes with directly in my iPad which is great. It has required me to iterate a couple of times to fix issues to do so. Thus, I assume that my XCode 7 (beta) environment is configured correctly. I have then created a new kit in QtCreator (3.4.1) pointing to the new XCode 7 (beta) and used it. The question is that I still see the message: === BUILD TARGET TestMultiPlatform OF PROJECT TestMultiPlatform WITH CONFIGURATION Debug === Check dependencies Code Sign error: No matching provisioning profiles found: No provisioning profiles matching the bundle identifier “com.TestMultiPlatform” were found. CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 8.4' that I used to see when I tried with XCode 6. To my knowledge, this should no longer happen since those problems also appeared initially in XCode 7 (beta) and after the fix issues thing they were gone. It feels like the configuration produced to fix them is not somehow captured by Qt Creator or some. So the question(s) is (are) 1) is XCode 7 supported/compatible with Qt5.4/QtCreator even though it is a BETA? 2) has somebody managed to build and run a Qt application in a device without purchasing any Apple Developer Program thing? 3) am I doing something wrong or missing something (I had followed the corresponding guides)? 4) is it possible to configure QtCreator, maybe even manually, to use the settings from XCode that work? if yes, how? regards. ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
