Media player stops working after 1 hour

rleiman · Dec 24, 2011

Hi Everyone,

Can you look at my code and tell me why the Media Player stops working after 1 hour?

While the screen is turned off it stops working after 1 hour has passed. If I turn the screen back on everything is normal.

The Media Player is used in a Service Module which should be running but stops after 1 hour after it is running.

It will work ok until after an hour has passed if I re-install the app.

I also noticed after 1 hour has passed the notifications also are not being updated.

Here is the Service Module I'm using. Sorry for such a large module:

B4X:

'Service module
Sub Process_Globals
   'These global variables will be declared once when the application starts.
   'These variables can be accessed from all modules.

   ' Media Player.
   '--------------
   Dim mpMediaPlayer As MediaPlayer

   ' Timers.
   '--------
   Dim tmrChimeTimer As Timer
   
   ' Phone.
   '-------
   Dim pwsPhone As PhoneWakeState

   ' Notifications.
   '---------------
   Dim ntfTheNotification As Notification
   
   ntfTheNotification.Initialize
   ntfTheNotification.Icon = "icon"
   ntfTheNotification.Sound = False
End Sub

Sub Service_Create

End Sub

Sub Service_Start (StartingIntent As Intent)

   ToastMessageShow("Chimes is now active.", False)

   ' This will be used to play the chimes.
   '--------------------------------------
   mpMediaPlayer.Initialize2("MediaPlayer")
   mpMediaPlayer.SetVolume(1, 1)

   ' Start the Timer.
   '-----------------
   tmrChimeTimer.Initialize("tmrChimeTimer", 1000)
   tmrChimeTimer.Enabled = True

End Sub

Sub Service_Destroy

End Sub

   intHour = DateTime.GetHour(intTheCurrentDateTime)

We tried that and the sound plays as if the sounds is turned on and off at random intervals. It's ok when the phone is plugged in to is turned on.

That's why we need to schedule alarms like you can do in Java even though I don't know much about Java. That's why we are using B4A.

Use StartServiceAt. This is exactly what it does.

Erel · Dec 28, 2011

What I'm saying is that StartServiceAt is exactly the Java implementation that you are talking about. If it doesn't work then a custom Java implementation will not work as well.

Correct me if I'm wrong, but then there are certain things cannot be done using a service like downloading a file if the phone is locked.

Erel · Dec 28, 2011

Download will not stop immediately. Only when the OS decides to either pause the CPU or close the network connection.

Media player stops working after 1 hour
