    All,

    'am running the following code snippet in Qt to get the screen size of my android virtual device.

    QApplication app(argc, argv);
     
     QDesktopWidget *mydesk = app.desktop();
        // redundant but using both showFullScreen and showMaximized...
        // ...just to play it safe
        mydesk->showMaximized();
        mydesk->showFullScreen(); 
    
      QScreen *screen = app.primaryScreen();
        int width = screen->size().width();
        int height = screen->size().height();
    

    I created a Nexus 5 Android Virtual Device with resolution 1080x1920 to test my code and my width and height values are 1080x1776 instead of the expected 1080x1920. What 'am I doing wrong here? Can someone please help me?

    Thanks

      Hi,

      Just a wild guess, but isn't that the size without the top bar ?

        Thanks @SGaist. My guess was the same but I do not know how to prove it. Any thoughts?

          Does your application cover the status bar ?

            Hi
            You dont really have to prove it.
            Many other have wondered.
            https://forum.xda-developers.com/xperia-z/general/hd-t2238929

            1080x1776 too much a magic number to be a coincidence ( IMHO)

            I wonder when you create a Nexus 5 Android Virtual Device, it must know from some where
            the size of the bar.

            But if app covers bar ( as @SGaist asks) then it might be bug in the virtual device as as far as i know
            (some) info apps will report full size if app is fullscreen.

              Thanks @SGaist and @mrjj . My app does not cover the status bar. It is just a test app/Hello World type app that displays the resolution on the screen (so not much to the code than what i posted here). I will try creating an app that covers the status bar and see how that behaves.

              Thanks again
