[KhuramKhalid]

When i play the audio the app crashes and i get this error on Android Studio:

E/AndroidRuntime: FATAL EXCEPTION: main

I've set this value in AndroidManifest.xml but it still without work:

meta-data android:name="com.google.firebase.messaging.default_notification_icon" android:resource="@mipmap/ic_launcher"

I'm using the package "flutter_launcher_icons: ^0.7.4" for generate the icons of my app, can this be the problem?

Yes so the issue here is definitely the icon. What you can do is just manually create a notification icon and call it ic_notification_icon. That should resolve the issue.

The same issue for me, any solution?

[KhuramKhalid]

Can you share some logs from the device? What's the exception you're seeing?

[vvasc]

Same problem here, on iOS works fine, but when I try on Android phones the app crashes. This may happens because I'm using an .m3u to listen audio.

[vvasc]

I test with .m3u8 and same problem occur

[KhuramKhalid]

What's the exception you see?

[KhuramKhalid]

One reason for an app crash could be that the notification icon (ic_notification_icon) isn't setup for Android project. That definitely causes apps to crash on Android.

[vvasc]

@KhuramKhalid Even with ic_notification_icon the app crash. In example provided in package the same problem occur on Android. Could you provide an example to solve that?

I'm using to configure my notification_icon in Android Manifest:

         <meta-data
            android:name="com.google.firebase.messaging.default_notification_icon"
            android:resource="@drawable/ic_notification_icon"/>

Thank you for fast answer and to maintain this repo

[KhuramKhalid]

That config looks good so notification icon isn't an issue. Would it be possible for you to share your m3u8 url? We're using this player with our video on demand app which also includes live streaming and all assets are HLS (m3u8) and they all work fine. So not sure what the issue is. Will have to dig deeper. Also if possible, please share device logs from Android Studio when the app crashes.

[vvasc]

My url is https://s18.maxcast.com.br:8010/autodj.m3u

[vvasc]

Using an external Android device I've a strange behaviour, without crash, but also without the audio playing and override error function i got:

"MEDIA_ERROR_UNKNOWN: Unspecified media player error"

With iOS, using emulator or external devices everything works properly

[KhuramKhalid]

My url is https://s18.maxcast.com.br:8010/autodj.m3u

Sorry I wasn't able to look at it earlier and now it seems the service is offline. Please let me know when it's up and I'll have a look.

[KhuramKhalid]

Ok so I was able to play it with the sample app. Firstly use this url https://s18.maxcast.com.br:8010/autodj instead of .m3u. Secondly, it take about 30 seconds after pressing play button for the audio to start. Not sure why that delay is, probably some config issue on server side.

[vvasc]

@KhuramKhalid Thank you for help me, it work now and I'll look my server

[KhuramKhalid]

@vvasc you've welcome. @hemadri-divii @Batres35 are you still having this issue?

[Batres35]

One reason for an app crash could be that the notification icon (ic_notification_icon) isn't setup for Android project. That definitely causes apps to crash on Android.
