Regarding the preview of the camera in Android

[Pradeep Kumar]

Hi,

I am using Qt 5.7 version, and trying the camera application in Android, but the problem is i am not getting the preview?.
I want to capture the image,
I am using the code below.
{
this->setFixedSize(700,500);

m_button = new QPushButton;
m_button->setText("Start Camera");

m_captureImage = new QPushButton;
m_captureImage->setText("Capture Image");

m_cameraObj=new QCamera;
m_imageCapture = new QCameraImageCapture(m_cameraObj);

m_viewfinder = new QCameraViewfinder;
m_viewfinder->setFixedSize(400,400);
m_viewfinder->setVisible(false);
m_viewfinder->setSizePolicy(QSizePolicy::Maximum,QSizePolicy::Maximum);
m_cameraObj->setViewfinder(m_viewfinder);

m_hbox = new QHBoxLayout;
m_hbox->addWidget(m_button);
m_hbox->addWidget(m_captureImage);

m_vbox = new QVBoxLayout;
m_vbox->addLayout(m_hbox);
m_vbox->addWidget(m_viewfinder);
setLayout(m_vbox);

connect(m_button,SIGNAL(clicked()),this,SLOT(getCameraImage()),Qt::UniqueConnection);
connect(m_captureImage,SIGNAL(clicked()),this,SLOT(getCapturedImage()),Qt::UniqueConnection);

}

void CameraFrame::getCameraImage()
{
m_cameraObj->start();
}

void CameraFrame::getCapturedImage()
{
m_imageCapture->capture();
}

Any clue why it is not showing preview. Even with the sample code of camera which is provided by Qt is not showing preview in Android, Guidance is required.

Thanks,
}

I got it we need to load QML Component to Qt .
Add to a layout and then view.
