Android Question Empty form after notification

[AHilberink]

Hi,

I try to build my first app based on a service. The service is starting well, also on boot.

The service will make a notification. From the notification I want be back to my form of the process. This happens, but the form is empty. The form only contains a button and a edittext.

Here is the source of the process:

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

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

    Dim EditText1 As EditText
    Dim Button1 As Button
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    If(FirstTime=True) Then
        StartService(CIRISChecker)
        Activity.LoadLayout("Main")
    End If
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Here is the source of the service:

#Region  Service Attributes
    #StartAtBoot: True
    #StartCommandReturnValue: android.app.Service.START_STICKY
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Dim n As Notification
    Dim Aan As Boolean
End Sub

Sub Service_Create
    'This is the program entry point.
    'This is a good place to load resources that are not specific to a single activity.

End Sub

Sub Service_Start (StartingIntent As Intent)
    'schedule the service to start every 2 minutes. Note that StartAtBoot is set to trye
    StartServiceAt(Me, DateTime.Now + 2 * DateTime.TicksPerMinute, False)
    If(Aan) Then
        n.Cancel(1)
        Aan=False
    Else
        DisplayIcon
        Aan=True
    End If
End Sub

Sub Service_TaskRemoved
    'This event will be raised when the user removes the app from the recent apps list.
End Sub

'Return true to allow the OS default exceptions handler to handle the uncaught exception.
Sub Application_Error (Error As Exception, StackTrace As String) As Boolean
    Return True
End Sub

Sub Service_Destroy

End Sub

Sub DisplayIcon
    n.Initialize
    n.Icon = "check"
    n.SetInfo("CIRIS Example", "Nieuw berichten ontvangen...", Main)
    n.AutoCancel = True
    n.Notify(1)
End Sub

It is a short code only for testing.

Do I have to reload the layout and how?

Best regards,
André

I think you need to pass the values in a specific way, so maybe this https://www.b4x.com/android/forum/threads/pass-a-reference-of-a-view-to-a-service.49710/

or this?

your only loading the layout at firsttime, views can be destroyed in the background thats why your form is empty , i guess

Hi Ronell,

Thanks.

If I do so, the form is reloaded but the value of EditText will become empty everytime.

Hi Eps,

Thanks you for your reply. This will save the values and with the reply of Ronell it should be possible to retrieve the values. I will investigate this.

Best regards,
André

save the value in a file? or in any other way so that you can retrieve it

File.WriteString(File.DirDefaultExternal,"savetext.txt",edittext.text)
