Android Question Problems with MediaPlayer as Service

[ernschd]

Hello,
i've got two Problems.
First, i have an application with an Activity, a MediaPlayer and a Layout "PlayerLayout".
I'm calling then MediaPlayer as a service because it should stay active in the background.

My Activity:

Sub Activity_Create(FirstTime As Boolean)
  Activity.LoadLayout("PlayerLayout") 
  If FirstTime Then
    playerService.MediaPlayer1.Initialize2("MP")
  End If
End Sub

Sub MP_Complete 
  ' Play next Song
End Sub

The Service:

Sub Service_Create 
End Sub

Sub Service_Start (StartingIntent As Intent)
  MediaPlayer1.Play 
End Sub

Sub Service_Destroy
  MediaPlayer1.Pause
End Sub

After the Screen is locked, the Event MP_Complete never gets invoked.
I wanted to update the Player-GUI with a Timer in the Activity. Do i have to do this out of the Service?

Second Problem: i like do implement a Headphone control:

Sub Activity_KeyPress (KeyCode As Int) As Boolean
  If KeyCode = 79 Then   
    ' next Song
  End If 
End Sub

Is it possible to do this in a Service?

Thanks and Regards

You should initialize MediaPlayer in the service and also handle the event in the service.

You can use CallSubDelayed to call a sub in the service.
