Start Audioservice on "initState"

[yagoliveira92]

I want start the notification in app initialization, but don't play anything. I try, in the example, put this code in "initState":

@override void initState() { super.initState(); WidgetsBinding.instance.addObserver(this); connect(); AudioService.start( backgroundTask: _backgroundAudioPlayerTask, resumeOnClick: true, notificationChannelName: 'Audio Service Demo', notificationColor: 0xFF2196f3, androidNotificationIcon: 'mipmap/ic_launcher', ); }

But don't working. Anyone can help me? =D

You should execute AudioServiceBackground.setMediaItem(mediaItem) to display notification. As far as I understand you don't need to play anything for notification to be displayed.

Don't worked. I tried put
@override void initState() { super.initState(); WidgetsBinding.instance.addObserver(this); connect(); AudioServiceBackground.setMediaItem(mediaItem); }

In the Example but nothing happened

If I understand correctly, you want it to start in the "paused" state. Note the difference between the "paused" and "stopped" states: In both, there will be no audio playing, but in the "stopped" state, the Android service is actually stopped and the notification disappears, while in the "paused" state the service is still alive and the notification is still present.

To clarify Alex's suggestion, AudioServiceBackground.setMediaItem can only be called from within your background task, so you should put that call in the first line of your onStart callback.

So on the client side, you do this:

• AudioService.connect
• AudioService.start

And on the background task's onStart callback, you do this:

• Call AudioServiceBackground.setMediaItem to include the details to show in the notification
• Call AudioServiceBackground.setState to paused
• (anything else you need to do that's application specific)
• Return a future that completes when you are ready to shut down the service

That's work! Thanks!
