Android Question Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy

Hi,

I am getting this error from time to time:

Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@97d5fc4 is not valid; is your activity running?

My code is:

Public Sub MaakSynchroon
    ProgressDialogShow("Synchroniseren")
    RunningEnd=5
    Running=0
    OphalenLogo2(False)
    OphalenKantoor(False)
    OphalenKentekens2("A",False)
    OphalenKentekens2("C",False)
    OphalenKentekens2("K",False)
    OphalenMedewerkers
    WachtrijReset
    Starter.Nogmaals=False
    Starter.BezigMetOphalen=False
    Starter.OphalenMessages
End Sub

and is starterted from code:

Sub imvSynch_Click
    StateManager.RestoreState(Activity, "Hoofdscherm", 0)
    pnlWeging.Top=TopWeging
    StopService(GPSLocatie)   
    CallSubDelayed(Synchroniseer,"MaakSynchroon")
End Sub

Can someone tell me why this happening from time to time and what I can do to prevent this?
Normaly the imvSynch_Click is working fine.

Kind regards,
André

In which module is MaakSynchroon declared?

This error usually happens when trying to show a dialog from a service.

It is an Activity Module, not a service.

It is an Activity Module, not a service.

May be this will help:

Public Sub MaakSynchroon
    ProgressDialogShow("Synchroniseren")
    RunningEnd=5
    Running=0
    OphalenLogo2(False)
    OphalenKantoor(False)
    OphalenKentekens2("A",False)
    OphalenKentekens2("C",False)
    OphalenKentekens2("K",False)
    OphalenMedewerkers
    WachtrijReset
    Starter.Nogmaals=False
    Starter.BezigMetOphalen=False
    ProgressDialogHide
    Starter.OphalenMessages
End Sub

Added ProgressDialogHide before running a Sub from Starter service?

I will try......

Somehow the activity isn't running or isn't ready when you call ProgressDialogShow.

You can catch this error. Adding Sleep(0) might also help.

You mean like this:

Public Sub MaakSynchroon
    Sleep(0)
    Try
        ProgressDialogShow("Synchroniseren")
    Catch
        Log(LastException)
    End Try
    RunningEnd=5
    Running=0
    OphalenLogo2(False)
    OphalenKantoor(False)
    OphalenKentekens2("A",False)
    OphalenKentekens2("C",False)
    OphalenKentekens2("K",False)
    OphalenMedewerkers
    WachtrijReset
    Starter.Nogmaals=False
    Starter.BezigMetOphalen=False
    Starter.OphalenMessages
End Sub
