Qt Quick iOS: How to keep audio playing while app is in background

[julienchevet]

I'm developing a WebRadio application in qml for iOS devices. To play the audio stream I use the MediaPlayer type which works fine.

However, in iOS, when I switch to another application or go back to home, in other words when the app go to background, the sound is cut whereas I would like to keep it playing.

I know how to do it in objective-C by activating the AVAudioSession and add the audio background mode the info.plist file.

But I really don't know how to do it in qml.

Can someone help ?

Hi and welcome to devnet,

The modification of Info.plist is still a valid thing to do. As for AVAudioSession, you will have to write some native code (e.g. a little wrapper class)

Thanks for the welcome.

How can I do a little wrapper class with native iOS code.

Have you got some exemples ?

You can take a look at the qtmacextras module, it uses Objective-C++

@SGaist I've changed the ingo.plist but my audio is still pausing when I put my app on background, what should I do?

Did you also setup the AVAudioSession ?

@SGaist ,I meet the same situation, would you like help me?
The info.plist added audio background mode already.
The QML by QT 5.5 is:

Window {
    visible: true
    Audio{
        id: playMusic
        source: "test.wav"
    }
    MainForm {
        anchors.fill: parent
        mouseArea.onClicked: {
            playMusic.play();
        }

    }
}

Thank you!
