Problem with updating the widget

[schimanski]

Why is it not possible to update the widget out of an activity module?
I tried the following code, but the widget doesn't dates up....

'Service module of the widget (WidgetS)'
Sub Process_Globals
  Dim rv As RemoteViews
End Sub

Sub Service_Create
  rv = ConfigureHomeWidget("WidgetPortrait", "rv", 0, "Foxfinder",True)
End Sub

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

Sub rv_RequestUpdate
  Widget_check
End Sub

Sub Widget_check
  If Main.Passwortzugang=True Then 
    rv.SetTextColor("Label4",Colors.Green)
    rv.SetText("Label4","Aktiv")
  Else
    rv.SetTextColor("Label4",Colors.White)
    rv.SetText("Label4","Nicht aktiv")
  End If
   
  rv.UpdateWidget
End Sub

'Activity-Module'

  .....
  CallSub(WidgetS,"Widget_check")
  ...

Thanks for help....

Are you sure that the service is running? Check Log(IsPaused(WidgetS)).

 

[schimanski]

Why souldn't the service work? When I set the widget to the screen, the Log calls 'Service (widgets) Start. And after that, the service of the widget still runs. There is no pause in the log...

 

[Erel]

You are probably right, but it is worth checking it.

 

[schimanski]

The Log("Check WidgetS:" & IsPaused(WidgetS)) tells me 'false'. So the service is just running, or?

 

[Erel]

The service is running. Can you upload your project (or the relevant part of it)?

 

[schimanski]

Thanks for help, but it is a very big project. When the code I have posted have to work, I will try the widget in a small simple app. I tested it and call back....

 

[schimanski]

I have posted the small widget-code. It doesn't work...

 

[schimanski]

I have tested it several times, and sometimes it runs, but the most time not

 

[Erel]

I believe that my previous assumption was correct. The process eventually gets killed by Android. Then IsPaused will return True and CallSub will not do anything.
The solution is to start the service yourself:

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("L1.bal")
   StartService(WidgetService)
End Sub

You a task manager to test it. Kill the process and you will see that it will now work.

However you must also persist the current state.
Whenever something changes you need to store it in a file. Then in Service_Create you should look for the file and read the state from the file.

It should be pretty easy to do it with File.ReadMap / WriteMap.

Thanks, Erel. I will try it in the afternoon and call back...

Hello!

I have tried your example, but it doesn't work. Than I have installed it on my Galaxy Tab P 1000, and it runs very fine :BangHead:..

It don't works on my Motorola Defy. I have also tried to start the WidgetService each time, before I call

'CallSub(WidgetService,"Widget_check")',

but the same problem... What is the different between Defy and Galaxy Tab? Both devices are under Froyo...

 

[Erel]

Calling StartService before calling CallSub will not help, as StartService just sends a message to the message loop. Only later the service is started.

 

[schimanski]

O.k, I understand.
But I have tried something else and it seems, that it is not possible to update a widget on a motorola Defy. Is there perhaps another way to handle the update?

Thanks for your efforts..

 

[schimanski]

I have changed the code in the Service_start to the following and it runs on the Motorola Defy. The problem is, that the system is slowing down, when the widget is installed on the homescreen. I don't know why the following code runs on the defy. Is there someone who can see the problem?

Thanks...

Sub Service_Start (StartingIntent As Intent)

  If StartingIntent.Action = "android.appwidget.action.APPWIDGET_DELETED"  Then Return
   
  If rv.HandleWidgetEvents(StartingIntent) = False Then
    rv_RequestUpdate
  End If

  If StartingIntent.Action <> "android.appwidget.action.APPWIDGET_DISABLED" Then
    StartServiceAt("", DateTime.Now+30, False)
  End If

End Sub

    StartServiceAt("", DateTime.Now+30, False)

With this your widget gets updated every 30ms which is 33 times a second. Quite often I think.

Oh shit, it's ms and not s...Thanks
