Describe the bug
Same Issue with me in version ^4.0.3+1 #317

Production Google Play crash reports i have more than 79 people impacted with this error

It started from 20-4-2020 when i added flutter sound plugin and uploaded an update to google paly

Almost all the devices are huawei with android 8 and 8.1

I don't have a "Huawei Y7 Prime 2019 (HWDUB-Q), 3072MB RAM, Android 8.1" to test flutter run and give you the output. Is this information enough to know the bug?.. tell me if you need anything more

To Reproduce

1. Download and run the app and it crashes in the installation from google play. The problem shows in some phones not all of them.

Expected behavior
Don't crash in production
I only added this great and awesome plugin to record audio with the "FlutterSoundRecorder" module .. I don't need a background service to start when the app is installed

So make the service optional if its possible .. Thanks for your hard work we really appreciate it

[Larpoux]

Looking to your logs, it seems that you use a Flutter Sound version prior to 4.0.3.
I understand that you are in production, but please could you check 4.0.4+1 ?

I fixed a bug in 4.0.3 in the initMediaSession() procedure.

I realize that it is not cool to crash in the TrackPlayer code and you even do not need this feature. We really must find a way that TrackPlayer does not interfere when not needed.

@bsutton : did you work on this f**ing 'intent_service' ?
if yes, is it possible to backport your fixes in V4 ?

[3mrdev]

I'm pretty sure i was using ^4.0.3+1 .. I will try 4.0.4+1 and let you know but if it didn't work i will push an update without the background service in production for the sake of our customers. Then will try to help you with another way

[Larpoux]

Thanks. There is a problem with services. Probably the best for you is actually to remove the intent-filter in AndroidManifest.xml in your production App, until we find a good way to fix that.
Thank you again.

[bsutton]

Sorry no. You were looking into it so I've not touched it.

I had a brief look but the stack trace didn't match the code based and it
looked like you had made some code changes.

I've pushed a possible fix for this in the 5.0 branch.

Hi I'm interesting in the workaround too could you elaborate what is exactly to remove? I didn't see any intent-filter related to Flutter Sound.

Thanks a bunch

[Larpoux]

@ShiroYacha : do you still have problems ?
(I was thinking that this issue was fixed).

If you still have issues, please enter a new issue, (with your logs, of course, and the result of "flutter pub deps | grep flutter_sound" ).

[3mrdev]

Should i upgrade to the latest version and test it @Larpoux ?

[Larpoux]

Sure :-)
If you still continue to have problems, please enter a new issue, (with your logs, of course, and the result of "flutter pub deps | grep flutter_sound" ).
I really hope that everything fixed, now.
Good luck 😃 !

[ShiroYacha]

@Larpoux I'll update the latest version and see if I still get this error.. it wasn't happening on most devices just a subset on androids... I'll monitor and raise a new issue if it occurs, thanks!

[Larpoux]

This bug is supposed to be fixed. Please re-open if the issue still occurs.
