Android Question Unwanted Notification

MrKim · Jul 6, 2019

I made some minor changes to one of my apps and found that the Widget was leaving an unwanted and unremoveable icon on the notification bar. Found the appropriate thread:
https://www.b4x.com/android/forum/threads/automatic-foreground-mode.90546/
And added:

B4X:

Sleep(0)
Service.StopAutomaticForeground

as the last thing in Service_Start to all service modules. This resolved THAT issue however, my widget contains several Labels which open the main program. I found that opening the program put my icon on the notification bar - it would disappear when I closed the app but there was no reason for it to be there.

I have resolved the issue by adding the above code to each of the labels in my widget, ie:

B4X:

Sub Label1_Click
    StartActivity(Main)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub

However as I read it this shouldn't be necessary?
Am I missing something?

android:targetSdkVersion="26"

Can you post the Service_Start code?

I am assuming you are talking about the widgets service.
Here is the whole service:

B4X:

#Region  Service Attributes
    #StartAtBoot: False
    
#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 RV As RemoteViews
End Sub

Sub Service_Create
Try
     RV = ConfigureHomeWidget("swlwidget", "rv", 2000, "SwipeList",  False)'unrem for release
Catch
'    Log(LastException.Message)
    ToastMessageShow(LastException.Message, True)
End Try

End Sub

Sub Service_Start (StartingIntent As Intent)
    
    If RV.HandleWidgetEvents(StartingIntent) Then Return'unrem for release
    Sleep(0)
    Service.StopAutomaticForeground

End Sub

Sub Service_Destroy

End Sub

Sub RV_RequestUpdate
        RestoreWidgetData
End Sub

Sub RV_Disabled
    StopService("")
End Sub

Sub SwLPnl_Click
    StartActivity(Main)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub
Sub Label1_Click
    StartActivity(Main)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub
Sub Label2_Click
    StartActivity(Main)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub
Sub Label3_Click
    StartActivity(Main)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub
Sub Label4_Click
    StartActivity(Main)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub
Sub Label5_Click
    StartActivity(Main)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub
Sub Label6_Click
    StartActivity(Main)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub
Sub Panel1_Click
    StartActivity(Main)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub

You can see where I added ....StopAutomaticForeground to each of the Click events to prevent the spurious notification.

Correct code:

B4X:

Sub Service_Start (StartingIntent As Intent)
     RV.HandleWidgetEvents(StartingIntent)
    Sleep(0)
    Service.StopAutomaticForeground
End Sub

Thank you. The code I used came from the Widget tutorial.

There was no real explanation for the if.
