BTW: if you want to opt-out from Android-35 edge-to-edge
you have to add styles.xml and add in Manifest... activity... android:theme="@style/NormalTheme"
see the details here:
https://codereview.qt-project.org/c/qt/qtbase/+/630376

This worked for me...Thanks!

@BTSTOnline cool :)

@Pann Tapping into a a TextField , brings up the virtual keyboard - this is what corrects the safeArea . Programmatically bring up the virtual keyboard to achieves the same effect.

[garycho]

I figured out a temporarily workaround by bringing up the virtual keyboard, which initializes the SafeArea margins correctly, and hide the keyboard immediately. At your constructor add this

connect(QGuiApplication::inputMethod(),SIGNAL(visibleChanged()),this,SLOT(closeKeyboard()));
QGuiApplication::inputMethod()->show();

Then create a slot

void MyApp::closeKeyboard()
{
    if (QGuiApplication::inputMethod()->isVisible())
    {
        QGuiApplication::inputMethod()->hide();
        disconnect(QGuiApplication::inputMethod(),SIGNAL(visibleChanged()),this,SLOT(closeKeyboard()));
    }
}

On activation of the virtual keyboard, the visibleChanged() signal will trigger the closeKeyboard() slot. This hides the keyboard and disconnects the signal/slot. You may get a glimpse of keyboard animating in/out... I find this to be a reliable workaround and easiest to undo , once this bug is fixed.

@ekkescorner Thanks for the information Looking forward to the fix. I've been spending too much time, finding ways around this bug.

[ekkescorner]

and 6.9.3 is here :) https://www.qt.io/blog/qt-6.9.3-released

edit: just did first tests with 6.9.3 on Android: now SafeArea values are there from start, also NavigationBar much better now :)

yep. always much time spending to report and follow all the bugreports and writing test applications like https://github.com/ekke/ekkesTestStatusBar
will update my test app next days with experiences from 6.9.3

@ekkescorner Excellent. Just compiled with 6.9.3 and the SafeArea margin is set correctly on start . The navigation bar is now grey instead of black.
