@Mena You can't do that, Apple doesn't allow that. just on a side note: Xamarin (a cross platform SDK similar to Qt) has recently introduced the possibility to run and debug iOs applications on Windows. Even though that sounds good at first, a Mac is still needed. What Xamarin is doing, is just forwarding all operations to a Mac that is connected via network. So while you are writing your stuff on a Windows machine, the actual build and run still happens on a Mac. That's again due to the restriction from Apple.

I did something similar, as I am storing JSON Web Tokens in the android keystore. As @SGaist already mentioned that's currently only possible via JNI. In case you need some help with the android keystore stuff, let me know.

Did you check again with QT_DEBUG_PLUGINGS set to 1 ? What did you get ?

Memory upgrade seems to help with my AVD issue. However, I am not completely sure why. The system has now 16 GB instead of 8 GB, but task manager shows a little less than 8GB used. Probably some parts used by win 10 are not properly listed respectively my interpretation is not completely correct. Anyway, the system has been simply 8GB memory added. There were no other changes required and suddenly the AVD start succeeded. This is despite the fact that I still have an error message The command "C:\Users\...\AppData\Local\Android\sdk\platform-tools\adb.exe" terminated with exit code 1. This is an AVD for ARM as I require for my Google phone. It consumes a 1.2 GB and has a reserved 2 GB according to task manager.

I changed permissions and also set the GENERIC_PLUGINS but still i dont see keyboard or mouse in a simple quick 2 gui in raspberry pi 3 any ideas?

Hi and welcome to devnet, QRadioTuner uses QRadioTunerControl internally. QRadioTunerControl is the base class for implementing the radio plugins. Currently there's only the V4L backend that provides support for radio. If you'd like to add support for digital radio, then you should likely implement a QDigitalRadioTunerControl and a QDigitalRadioTuner class and then create a plugin for whatever device that gives you access to the digital radio. Hope it helps

@Madhu-M-S said in Qt Application for Android and ios: Is there any Qt Application for Android and ios in google play store . yep - my last year's QtWS2016 Conference APP https://appbus.wordpress.com/2016/10/14/qt-world-summit-2016-conference-app/ based on QtQuickControls2

Hi @SamuelYeh , I didn't read your reply before. I think that you didn't add something like this in your .pro. I think that the error comes because you are not linking with libandroid. LIBS += -L/opt/android-ndk-r12b/platforms/android-19/arch-arm/usr/lib -landroid

@shav Thanks a lot for your kind help!

@GTDev Thanks for the reply. I will go on with V-Play and try to implement my app with V-Play for now. But if anybody has another idea why this happens I would be grateful for cheering.

@Sumit Should be possible, but I never used Bitbake

@sierdzio Thank you. I got it. I'll change its behavior in my code.

@epicedium Yeah! It has influence for the running. I hope you have solved it;)

I am also getting the error when i try to cross compile qt in raspberry pi 2 without x11. When i am running console application it is running. But when i am using widget application in pi touchscreen it is showing "Unable to query physical screen size, defaulting to 100 dpi. To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters)." and the system is idle can anyone help me with this when i am debugging the output in qtcreator is as follows Debugging starts Listening on port 10000 Remote debugging from host 192.168.15.153 Process /home/pi/qtinpitry created; pid = 8079 File transfers from remote targets can be slow. Use "set sysroot" to access files locally instead. Unable to query physical screen size, defaulting to 100 dpi. To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters). can anyone help me. Thanks in advance

Hi, Below is the bug link https://bugreports.qt.io/browse/QTBUG-59237 Regards, Avtansh Sharma

Thank you @SGaist !!! I will try it and tell if everything went well!!

@Mena on OSX I'm using http://lograbbit.com/ to get all logs. has comfortable filtering. but logs from LogRabbit are not inside QtCreator. I really like LogRabbit.
