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,

Add to a layout and then view.
