Android Question [SOLVED] Disappearing widget

[noeleon]

Hi.

Any idea why my app's 1x1 widget sometimes disappears from the homescreen? It's still there, if you remember where you placed it and long-press then click resize it shows again.

Panel is 60x60 with 60x60 imageview in it. The image is 512x512 pixels

Can you post your Service_Start code?

Are you calling rv.UpdateWidget in RequestUpdate event?

The sample project posted here https://www.b4x.com/android/forum/threads/10166
has an issue in Android 9, there's notification and icon that appears in the status bar so I added
Service.AutomaticForegroundMode = Service.AUTOMATIC_FOREGROUND_NEVER
in Service_Create

Here's the entire WidgetService

#Region Module Attributes
   #StartAtBoot: False
#End Region

Sub Process_Globals
   Dim rv As RemoteViews
  
End Sub
Sub Service_Create
   Service.AutomaticForegroundMode = Service.AUTOMATIC_FOREGROUND_NEVER
   rv = ConfigureHomeWidget("w", "rv", 0, "Wedge it",True)
End Sub

Sub Service_Start (StartingIntent As Intent)
   If rv.HandleWidgetEvents(StartingIntent) Then Return
   SetImages
End Sub

Sub rv_RequestUpdate
   rv.UpdateWidget
End Sub

Sub rv_Disabled
   Service.StopAutomaticForeground
End Sub

Sub Service_Destroy
   Service.StopAutomaticForeground
End Sub

Sub ImageView1_Click
   State.IsDisabled
   If State.isDisabled = True Then
       State.Off(False)
       ToastMessageShow("Turned ON",False)
   Else
       State.Off(True)
       ToastMessageShow("Turned OFF",False)
   End If
   SetImages
End Sub

Public Sub SetImages
   State.IsDisabled
   If State.isDisabled = True Then
       rv.SetImage("ImageView1", LoadBitmap(File.DirAssets, "off.png"))
   Else
       rv.SetImage("ImageView1", LoadBitmap(File.DirAssets, "on.png"))
   End If
   rv.UpdateWidget
End Sub

This code is wrong. You cannot disable automatic foreground mode. It will cause your app to crash.

You are missing some of the code from the tutorial.

    Sleep(0)
    Service.StopAutomaticForeground

Yes my app crashes a lot because of that.

Can you please update the Widget sample project so that it won't show notification in Android 9?

 

[noeleon]

i declared a notification variable and called notif.cancel
I think it works.

EDIT. Not working

 

[noeleon]

SOLVED.

I added

sleep(0)
Service.StopAutomaticForeground

at the end of most of my subs
