[jibinjayachandran]

Which API doesn't behave as documented, and how does it misbehave? AudioPlayer.setUrl('https://api.moodstream.anothercircus.com/api/m3u8?mood=4') not working in android device and it gives ExoplaybackException

void main() {
AudioPlayer _player = AudioPlayer();
await _player.setUrl('https://api.moodstream.anothercircus.com/api/m3u8?mood=4');
 _player.play();
}

To Reproduce (i.e. user steps, not code) Steps to reproduce the behavior:

@ryanheise Could you please help me on this issue I'm facing on android ?

I resolved this issue by setting the url as HlsAudioSource and it works fine both in andorid and ios.

await _player.setAudioSource(
          HlsAudioSource(Uri.parse(url)));

but in server , it hits too many times.

@ryanheise Could you please suggest me why this is happening and How do I resolve this ?

Thanks for doing some exploration. Yes regarding the behaviour of setUrl, it can only try to guess whether it should be HLS by looking at the extension. Since your URL doesn't follow that convention of using an extension in the filename, it fails to guess. So if you are in control of the server, another option (besides directly using HlsAudioSource) is to change the endpoint to something like /api/something.m3u8.

Regarding the server logs, I think that once you're actually getting it to detect that it's HLS, then the plugin uses the native Android or iOS system to play that stream, and in the above case, that is Android's ExoPlayer making all those calls. Maybe you can test other Android apps with the same URL to see if they hit the server in the same way.
