Qcamera viewfinder not working on android

[jsulm]

@slavisac Then I guess you can't do it with Qt widgets

@slavisac

create a qml file with a Camera component, make sure to give it some object name eg: objectName: "camera"

Load the qml file via QQuickWidget

do the following inside your c++ class to get access to the QML Camera component

ui->quickWidget->setSource(QUrl(QStringLiteral("qrc:/Camera/FrontCam.qml")));
    camera = ui->quickWidget->rootObject()->findChild<QObject*>("camera")->property("mediaObject").value<QCamera*>();
//camera is a QCamera  pointer

@slavisac
did you add
QT += quickwidgets to your project file ?

and clean & rerun qmake afterwards?

[slavisac]

@J.Hilk
