React-native-track-player: Background mode not working ?

[Begoodi]

Issue

I'm currently use react-native-track-player to stream audio from Internet. Works fine.

I would like now to use it in background mode, to be able to continue to listen to radio if my ap is in background mode.

I followed instructions from https://react-native-kit.github.io/react-native-track-player/background/, so add capabilities in xCode, with should be enough.

It doesn't work so I also add

TrackPlayer.updateOptions({
    stopWithApp: false
});

but stil not working.

Any idea or experience with this audio library in background mode ? Thanks !

I'm also getting this issue in iOS release mode.
react-native: 0.61.4 => 0.61.4

Anyone an idea ?
The extension looses its usefulness if not being able to play in the background!
Is it working well for someone ?

[mynameisguy]

try selecting Background processing as well in Background modes:

it worked for me.

@mynameisguy I've been trying to make this fixes for a week now. What you mentioned didn't work for me.
Some more info from my specific case:

• The app gets killed after ~50 sec on a physical device.
• This issue only appears on iPhones older than iPhone 11 on iOS 13.x
• App doesn't get killed if no audio is playing
• The app kill gives no errors the only logs in XCode are:

It seems the app gets killed because it uses too much CPU in background?

[Saehanseul]

Does IOS 13 need to add "Background Processing"?
It seems need to add "Permitted background task scheduler identifiers"
I'm confusing of the value in this.

[Begoodi-Dev]

This module does not work in background mode with iOS 13.
Is there any plan to update it ?
Or does anyone know another audio module that can work in background mode with iOS 13 ?

[zaptrem]

Any change on this? I'm dealing with the signal 9 crash as well.

[Saehanseul]

This module works in background mode.
We use this module as a production music app.
If it doesn't work in the background, it could be another issue like memory leak.

[Sathyanarayan09]

@Saehanseul can you please confirm the versions which your using RN -v and trackplayer -v
This is happening for us after first song ends and after fetching song in the background, player goes to pause state and gets killed

[notYarn]

Yep, this problem still exists. @curiousdustin do you have ideas about this problem?

[curiousdustin]

You do not need the Background Processing mode to be enabled for this react-native-track-player.

I can also confirm that background playback does work in my production app in iOS 13.

For those experiencing the issue, are you able to reproduce the issue using the example app?

[zeritte]

I experienced this error and it is not related to the library. Please check your app's performance thru xcode. In my case, I had a memory leak caused by useTrackPlayerProgress(500). After setting it to "1000", the error is gone.

[zaptrem]

Thanks! I haven't tried it yet but that very well may be my problem. What
caused the memory leak and why did this change fix it? Or does it just
delay the crash by slowing down but not preventing the memory leak?

It was working well on android but on iOS it was getting signal 9 error from xcode. The only reason was this hook and after editing it the error is gone. I update my screens by using position and duration values useTrackPlayerProgress hook provides. However, they (my screens) were getting updated unnecessarily when I go to background. So I implemented a simple logic:

const [appState, setAppState] = useState("active");
 useEffect(() => {
    AppState.addEventListener("change", appStateChange);
    return () => AppState.removeEventListener("change", appStateChange);
  }, []);

  const appStateChange = appState => {
    setAppState(appState);
  };

After getting app state information to state; I updated my component:
const { position, duration } = TrackPlayer.useTrackPlayerProgress(appState !== "active" ? 5000 : 500);
Meaning that it does not unnecessarily updates my component when app is in the background mode. Hope this helps!

[yuriceschin]

I had the same problem of background audio not working and after hours I noticed that on the Setup initialization I had iosCategoryMode: "spokenAudio".
I corrected it deleting it and setting it to "default" and this solved my problem.
I'm writing this just to help if someone else has made the same mistake.

[idir-s]

I had the same problem with iPhones older than iPhone 11. I think the reason is like said @FrankGoortani "It seems the app gets killed because it uses too much CPU in background".

I reproduce this bug with the example. I use an iphone 7 (physical device)

Any idea to fix this ?

[fpgce]

@idir-s I not have this issue in my iphone7

[ztowne13]

I had all of that stuff added too and it wasn't working. All I had forgotten was
TrackPlayer.setupPlayer();
so make sure the track player is initialized (even if the audio is already working!) because my audio worked, just not in the background, even though I forgot to initialize the track player.

[NedyUdombat]

I am currently experiencing this problem. Does anyone have know a fix?

We've run into this same issue in our application. After some thorough debugging in XCode, we've found the issue to be messages being issued the native system from the useTrackPlayerProgress hook, as @zeritte mentioned above. The fix they suggested also works--making the sole parameter of the hook a number larger than the default of 1000. I used 50000 in my case, because the time to app crash turned out to be geometric to the increase in that value, i.e.: a value of 4000 crashed in the same amount (roughly) that the 1000 setting would, but 4800 would run for over 20 minutes before crashing, where 5000 seems to never crash. The value of 50000 should give us an interminal play period, and is probably overkill.

The root of this must be in the track player library. Aside from this duration parameter, there's nothing else exposed through the API which we could be misusing.

Below is the code I used for the fix. It is very similar to @zeritte's code:

  const [appState, setAppState] = useState('active')
  const appStateChange = appState => setAppState(appState)
  useEffect(() => {
    AppState.addEventListener('change', appStateChange)
    return () => AppState.removeEventListener('change', appStateChange)
  }, [])

  const { position, bufferedPosition } = useTrackPlayerProgress(
    appState === 'active' ? 1000 : 50000
  )

It is also worth noting that I found this impossible to duplicate on any iOS simulator target that I tried, both before and after the iOS 14.0 release that broke so many media-related things. I was also unable to reproduce it on an old iPad Mini 3 running iOS 12 that was tethered to my Mac via XCode.

Had exact same issue and the above works like charm. Thanks
