Getting screen size of Android virtual device

[Treazy]

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.

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
