I've tried about every idea I can come up with to have a Springboard screen display a ProgressIndicator when I add an AudioPlayer, but I'm not getting something right. The screen displays the "audio" style when I add the SetDescriptionStyle ("audio") and I have the ContentType = "audio" along with the setProgressIndicatorEnabled(true). I've been hacking the following relevant code. Can you see anything that prevents the progress bar from being displayed.

springBoard = CreateObject("roSpringboardScreen")
				springBoard.SetBreadcrumbText("Breadcrumb Text","")
				port = CreateObject("roMessagePort")
				springBoard.SetMessagePort(port)
				springBoard.SetDescriptionStyle("audio")
				springBoard.setProgressIndicatorEnabled(true)
				springBoard.setProgressIndicator(0, 1)
				springboard.AllowUpdates(true)
				springBoard.Show()
										
					audioPlayer = CreateObject("roAudioPlayer") 	
					port = CreateObject("roMessagePort") 		
					audioPlayer.SetMessagePort(port)
						
					song = CreateObject("roAssociativeArray")
					song.url = "http://www.my.music.com/song.mp3
					song.ContentType = "audio"
					song.Title = "Title"
					song.Artist = "Artist"
					song.Album = "Album"
					song.HDPosterUrl = "pkg:/images/test_188x188.png"
					song.SDPosterUrl = ""
					springBoard.SetContent(song) 'adds song
					audioplayer.addcontent(song) 
					audioplayer.setloop(false)				
					audioplayer.play()
					springBoard.Show()
						while true
						msg = wait(0, port)
						if type(msg) = "roAudioPlayerEvent"
						if msg.isStatusMessage() then
						print "roAudioPlayerEvent: "; msg.getmessage()
						if msg.getmessage() = "end of playlist" return
						endif
						endif
						end while

Hi,

you need to update the first parameter of the progress indicator with the amount of time passed. (0,1) indicates your content is one second long, which is unlikely, so you need to set a timer with roTimeSpan:

timer=createobject("rotimespan")
timer.mark()

set the length of the track:

springboard.setprogressindicator(0,lengthOfTrackInSeconds) 

and count how many seconds have passed since the start with

springBoard.setProgressIndicator(timer.totalseconds(), LengthofTrackInSeconds)

note that LengthOfTrackInSeconds is just an arbitrary name, use whatever variable you have for the actual length of the track.

You might want to listen for the status message "start of play" before displaying and updating your progress indicator, so that it is more accurate.

Thanks Joel. I'm still missing something here. As a test, I changed the setprogressindicator to:

springboard.setProgressIndicator(0,10000)

just to see if the indicator would display and I'm not getting it to even show up. I tried changing the first variable to simulate the track in progress and it makes no difference. I've tried making a few changes and still nothing. Anything else you can see?

what if you set the progress indicator to (100,1000) do you see anything?

Also, you need to set your msg=wait(0,port) to a number higher than 0, like msg=wait(100,port) or nothing will update because your program will stop and wait for input, so it can't possibly update the screen.

I am having this same exact issue. Is there a sample app that demonstrates an roAudioPlayer which shows the progress bar? I cannot find one anywhere.

Also, where is the progress bar supposed to appear? In different SDK docments, it shows it in different places. The ComponentReference.pdf shows the progress bar at the bottom of the screen. But the MockUpTool.pptx shows the progress bar right below the poster image.

This would imply one could configure the screen to do one or the other, but I see no such option. So where would/should it appear given this?

I'm not sure what you're looking at in the component reference, but the progress bar for audio shows under the poster/icon on the roSpringboardScreen. Only the roVideoScreen has a progress bar at the bottom of the screen.

Interesting. I never noticed that before. I'm pretty sure it's an error in the mock-up. The progress bar is definitely under the poster.
