Service terminated

[wl]

Hello,

I have a test application with just one activity with a button.
Clicking on the button starts a service ("start at boot").

In the destroy event of the service I restart the service after 10 seconds.


When I kill the application using a task kiler it seems both the activity and the service are stopped and the service is not restarted after 10 seconds. What am I missing ?

Thanks !

I asked a similar question.

It seems that once the process (not the activity) is terminated, the service is terminated along with any service scheduling. In your case don't ExitApplication to keep the process and therefore the scheduled service alive. If I understand correctly Android will not immediately kill the process once you have exited the activity.

ok thanks, I missed this ...

But will Android decide one time or another to kill the process (and the service along with it) ?

And if so: will I get into the Service Destroy event so I can restart it after 5 seconds ?

Yes, unless you call Service.StartForeground.

And if so: will I get into the Service Destroy event so I can restart it after 5 seconds ?

It should work.

Hi,

It seems Android keeps killing the service with the open (but idle) TCP connection ? Running the service in foreground is lethal for the battery ...

Running the service in the foreground doesn't have any special effect on the battery. It just prevents the service from being killed which is exactly what you are trying to achieve.

Your solution will have the exact same impact on the battery.

I tried to put the service in the foreground, as follows

Sub Service_Create
   notif.Initialize
   notif.Icon ="icon"
   notif.Vibrate = True
   notif.Light = True
   Service.StartForeground(1, notif)
End Sub

But the application crashes and this is in my log files:

android.app.RemoteServiceException: Bad notification for startForeground: java.lang.IllegalArgumentException: contentView required: pkg=net.wapps.mpush id=1 notification=Notification(vibrate=default,sound=default,defaults=0xffffffff,flags=0x40)

Anyone an idea ?

Thanks !

Think I found it myself:

Needed to set the SetInfo first and call the StartForeground in Service_Start

Sub Service_Start (StartingIntent As Intent)
   notif.SetInfo ("Notification", "Foreground", Main)
   Service.StartForeground(1, notif)
End Sub

What I notice is that when I lock the phone by pressing the on/off button (not shutting it down!) after a while the service stops responding.

When I press the on/off button again the service kicks in again.

How can I make sure the service continues when I press the on/off button ?

Thanks !

See PhoneWakeState from the Phone library. You should use PartialLock.
