Android Question Notification

Hi, is there a way to send a notification after a tot of time even if the application is closed? for example, to alert the user that something it is recharged thanks

 

Hello,
Yes using a service. You will initialize the notification from it. The point you will have to think about is the activity shown if the user clicks on the notification itself.

 

Thanks but what service?

 

Hello Guido,
Not sure I do understand the question. If you are asking what a service is, may I suggest you take a look at this : http://www.b4x.com/android/forum/threads/service-modules.7542/#content or to the documentation : http://b4x.com/android/documentation.html
If the question was about the kind of service, you choose the name, the frequency it is launched or even if it should stay running

 

I want send a notification also when the app iso closed. No in background but close

 

So the service is the way to go. Give it a try

 

Yes i see, infact the notification works. But only when i close the app and this remains in background. If i kill the app notifications don t work

 

would you post your code ? Perhaps do You kill the app manully so you kill the service too ?

 

for example
- In Main

Code:

Sub btnCreateNotifications_Click
    StartService(notifica)
   
End Sub

-In Notifica

Code:

#Region  Service Attributes 
    #StartAtBoot: False
#End Region

Sub Process_Globals
    Dim timer1 As Timer
End Sub
Sub Service_Create
timer1.Initialize("timer1",7000)
End Sub

Sub Service_Start (StartingIntent As Intent)
    timer1.Enabled=True
End Sub

Sub Service_Destroy

End Sub
Sub timer1_tick
        Dim n As Notification
        n.Initialize
        n.SetInfo("Notification " & 1, "abcde", Me)
        n.Icon = "icon"
        n.Notify(1)
        timer1.Enabled=False
End Sub

 

perhaps do You want to restart the service when you stop the app ? If yes, you could try to insert a
StartServiceAt in Service_Destroy ?

 

An app which is killed CANNOT show any more notifications... The app is NOT running.
