How to detect Rotate on Android?

Hamlet

Hi,
I want to detect rotate on Android.

on MainWindow::MainWindow(QWidget *parent),
I use QScreen event: orientationChanged

QScreen *s = QGuiApplication::primaryScreen();
    connect(s, SIGNAL(orientationChanged(Qt::ScreenOrientation)),
               this, SIGNAL(orientationChanged(Qt::ScreenOrientation)));

     s->setOrientationUpdateMask(
                Qt::PortraitOrientation
                | Qt::LandscapeOrientation
                | Qt::InvertedPortraitOrientation
                | Qt::InvertedLandscapeOrientation);

void MainWindow::orientationChanged(Qt::ScreenOrientation orientation)
{
    qDebug() << "Orientation:" << orientation;
}

in header:

public slots:
void orientationChanged(Qt::ScreenOrientation orientation);

but the event orientationChanged not fire.
How do I get event when Android rotate?

Take a closer look at your code:

connect(s, SIGNAL(orientationChanged(Qt::ScreenOrientation)),
               this, SIGNAL(orientationChanged(Qt::ScreenOrientation)));

You use SIGNAL where you actually should use SLOT.
Change it to:

connect(s, SIGNAL(orientationChanged(Qt::ScreenOrientation)),
               this, SLOT(orientationChanged(Qt::ScreenOrientation)));
