App in Background Or Lock Phone Then Spatial Audio Selector Not Working

KetanSodvadiya

Hello,

For Spatial Audio,

Here we Declare Variable of CADisplayLink ->

private var AudioUpdater: CADisplayLink?

And Play Audio Function we write code for Play Spatial Audio ->

spatialNotificationAudioUpdater = CADisplayLink(target: self, selector: #selector(self.AudioUpdateUI))

And this function is used when my spatial start playing

 @objc func AudioUpdateUI() {

        AudioCurrentPosition = AudioCurrentFrame + AudioSkipFrame

        AudioCurrentPosition = max(AudioCurrentPosition, 0)

        AudioCurrentPosition = min(AudioCurrentPosition, AudioLengthSamples)

        // if reached end of audio file

        if AudioCurrentPosition >= AudioLengthSamples {

       }

}

When i play audio in Foreground mode then AudioUpdateUI() function is called but when my app is on Background (Phone Lock) then AudioUpdateUI() function is not Called.

Thanks,
Ketan.

Hi @KetanSodvadiya ,

Did you put break points and logging statements? What are those looking like?

we we added breakpoint in  @objc func AudioUpdateUI() {} function breakpoint is called when my app is on Foreground Mode. But when my app is on background mode (Phone Locked) then breakpoint of @objc func AudioUpdateUI() {} is not Called.

And When my app in background mode then breakpoint not called and whenever i return to foreground mode then breakpoint working perfectly.

Here, can i missing to set any properties or anything else for setting spatial audio?

Thanks,

Hi @KetanSodvadiya ,

Did you implement a background task when your app enters background via the app delegate's didEnterBackground method?

Yes, I implement app delegate's didEnterBackground method and also Enable Background Mode from capabilities.
