[iOS] audio stops playing in background

[ralph-bergmann]

I tried the example app on a real iPhone device. When I switch the phone off audio stops playing. When I switch it on again it continue playing.

Do you have any hints?

I added audio to the UIBackgroundModes in the example/ios/Runner/Info.plist but it doesn't fixed the issue.

Wow, is it true? Because background playing is a critical for my application.

[ralph-bergmann]

yes, the mediaplayer.prepare method blocks the ui thread, if you have a hugh file the prepare methods needs a couple of seconds.

I managed to solve the issue with the background mode with this code and with the plist configuration UIBackgroundModes

do { try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, with: .mixWithOthers) try AVAudioSession.sharedInstance().setActive(true) } catch { print(error) }

@ficiverson I'm about to start a Flutter project and playing audio in the background is a core requirement. Can you please confirm that you were able to handle it with your workaround?

[ficiverson]

@omarrida For me its working on a radiostation app (only iOS version tested). Now I can listen to streaming music on background but I dont know if it works with local files because I dont have that requirement

The way to fix that is

1. Set AVAudioSessioncategory to playback mode, I proposed a fix waiting to be merged : pull request #43
2. Add ausio inUIBackgroundModes in your .plist files.

2. Add ausio inUIBackgroundModes in your .plist files.

I done： 1.AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)

2. UIBackgroundModes

   <array>
           <string>audio</string>

   It still can't play in the background.

fixed it, it work well try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, options: AVAudioSession.CategoryOptions.mixWithOthers) NSLog("Playback OK") try AVAudioSession.sharedInstance().setActive(true) NSLog("Session is Active") } catch { NSLog("ERROR: CANNOT PLAY MUSIC IN BACKGROUND. Message from code: \"(error)\"") }
