I have not seen *random* issues with QSettings on Android.
I have seen issues with users swiping the app and closing it that did not give
my widget app a chance to save settings.
Adding the following solved the problem by giving me chance to save settings:
#ifdef PLATFORM_ANDROID
/// Use signal QGuiApplication::applicationStateChanged(Qt::ApplicationState
state)
/// to catch Android and hopefull iOS users pressing the home or multi-task
button.
/// Under Android, users can press rectangular multi-task button,
/// this will change state to Qt:ApplicationInactive.
///
/// When exiting Qt::ApplicationActive state, save settings.
///
/// Is there any reason to disable this for desktop platforms?
void MainWindow::applicationStateChanged(Qt::ApplicationState state)
{
qDebug("Qt::ApplicationState %i", state);
static Qt::ApplicationState oldState = Qt::ApplicationSuspended;
if(oldState == state)
{
return;
}
oldState = state;
if(Qt::ApplicationActive == state )
{
// Fix attempt for Android half-portrait-screen on start-up
// Issue is reproducible on Sansung S4
// Bug 468 - [Android] App window size not full-screen on first open
// http://subsitedesign/bugzilla/show_bug.cgi?id=468
showMaximized();
return;
}
// This uses QSettings underneath
Settings::write(Settings::settings(), this);
}
#endif

Hi,
Does anyone here had problems with QSettings persistence on Android device?
I’m having random and occasional reports from users on Android telling me that
settings don’t persist.
Thanks,
