[Felgo User]

Hello everyone,

I am encountering an issue with Felgo Live on my Android device when using the camera in my application and I’m hoping someone here can assist me. I am using Felgo 4 on my development machine and version 2.0 of Felgo Live on my Android device running MIUI Global 14.0.4.

My application uses a NavigationStack and a camera feature. Here is a snippet of my code:

import QtQuick
import Felgo
import QtMultimedia

AppPage {
    id: controlPage

    title: qsTr("Control")

    Rectangle {
        anchors.fill: parent

        Camera {
            id: camera
            active: true
        }

        CaptureSession {
            camera: camera
            videoOutput: output
        }

        VideoOutput {
            id: output
            anchors.fill: parent
            fillMode: VideoOutput.PreserveAspectCrop
        }


        Image {
            id: image
            anchors.centerIn: parent
            width: 200
            height: 200
            source: ""
        }


        AppButton {
            text: "Open/Close photo"
            anchors.centerIn: parent
            onClicked: {
                camera.active =  !camera.active
            }
        }
    }
}

 

This code is used here with navigationStack.push() and navigationStack.pop() :

Component {
        id: controlComponent
        ControlPage {

        }
    }

 

Everything works perfectly when I run it on Felgo Live on my PC. However, when I use Felgo Live on my Android device, I encounter an issue after using navigationStack.pop(). After executing this command, my application becomes unresponsive. I can tap anywhere, but nothing happens. Moreover, I can’t even drag the Felgo Live bubble on the screen.

I tried to reproduce the issue on another Android device and encountered the same problem. I also checked the console of Felgo Live Server on my development machine, but I saw no error messages.

I noticed that the issue does not seem to be specific to my application, as even Felgo Live itself seems to be affected (I can’t drag the Felgo Live bubble).

I tried to search for a solution to this issue online, but I couldn’t find any useful information. I would greatly appreciate any help or suggestions you could provide.

Thank you in advance for your assistance.

Hi,

this is probably realted to https://bugreports.qt.io/browse/QTBUG-110868

We are currently evaluating Qt 6.5.2 for the next Felgo update, and will also verify a better stability of the Qt Multimedia module with this version.

A potential workaround for now could be to have the Camera related components in the root of your application and only show/hide them on demand, without destroying them (a page on a NavigationStack is created/destroyed on demand). So the camera will then not be part of a sub page, but rather an overlay of the application, which could probably also work for your app design.

Best,
Alex
