Playing a radio stream in the background iOS 4

[cordoprod]

Hello,
I'm using Matt Gallaghers AudioStreamer in my radio app.
It's just a stream that starts when the app launches, and stops when it quits. No play, pause, next or back controls.-
Therefore i dont need the iPod controls.

I've searched for it but i can't find a working way to implement this.
All i want is that the stream keeps playing if the user presses the home button.

iOS Application Programming Guide: Executing Code in the Background

I've already done that, but I can't seem to find a way to implement Matt's AudioStreamer to multitasking.

Seems to me you can add the audio task to the UIBackgroundModes property and wrap the call to start and stop in the audio in beginBackgroundTaskWithExpirationHandler and endBackgroundTask.

Ok, so I tried adding UIBackgroundModes and audio to Info.plist.
Still no luck. Doesn't work. Are there more stuff I need to implement to make it work?

Everything is in the article.

Did you even read my entire sentence much less the manual on backgrounding tasks?

Thats limited for playing 10 minutes on the background. The UIBackgroundModes isnt working for some reason.

It looks Audio Queue's dont support background playing for some reason... I can't find out why it doesnt work to move to the background and i do it exactly as in the WWDC session or as stated in the docs..

Looks like AudioStreamer uses Audiotoolbox not AVAudioSession therefore I do not believe it supports multitasking audio. This library supports Mac and iPhone.

AudioStreamer.h

#include <AudioToolbox/AudioToolbox.h>
...
AudioSessionInitialize (
...

I added in my code AVAudioSession and i added the correct key in the plist but it still doesnt work.

I used the following code:

	 UIDevice *thisDevice = [UIDevice currentDevice];
	 
	 if([thisDevice respondsToSelector:@selector(isMultitaskingSupported)]
		 && thisDevice.multitaskingSupported)
	 {
		 UIBackgroundTaskIdentifier backgroundTask = [application beginBackgroundTaskWithExpirationHandler:^{
			 /* just fail if this happens. */
			 NSLog(@"BackgroundTask Expiration Handler is called");
			 [application endBackgroundTask:backgroundTask];
		 }];
	 }

Place it in the didFinishLaunchingWithOptions.
This will work in the simulator, I don't have a iPhone 3gs or 4 so i'm unable te test it on a real device.

Thats limited to 10 minutes on the background, after that the app is quit by the OS.

This seems to work:
DigitalDJ's AudioStreamer at master - GitHub

Plays in the background, does not work in the simulator!!

[rrichar]

Can someone post example code on how DigitalDJ's AudioStreamer at master - GitHub works ?
