Android Question Panel will not remove after calling other app [SOLVED]

[jnjft]

Hello, I have a class with a method to display a message for a given time and then disappear again. This works fine in most cases, but if I e.g. start the default mail app after or before displaying such a message it will never be removed.

Here's the code for the Message Class:

Sub Class_Globals
    Dim Caller As Activity
    Dim pnmsg As Panel
    Dim pnmsgBg As ColorDrawable
    Dim lbmsg As Label
End Sub

Public Sub Initialize(Callback As Activity)
    Caller = Callback
    pnmsg.Initialize("pnmsg")
    pnmsgBg.Initialize(Colors.ARGB(240, 80, 150, 200), 20)
    pnmsg.Background = pnmsgBg
    pnmsg.Height = 100dip
    lbmsg.Initialize("lbmsg")
    lbmsg.Gravity = Bit.Or(Gravity.CENTER_HORIZONTAL, Gravity.CENTER_VERTICAL)
    lbmsg.TextSize = 16
    lbmsg.TextColor = Colors.White
    lbmsg.Color = Colors.Transparent
    lbmsg.Visible = True
    pnmsg.AddView(lbmsg, 0dip, 0dip, 80%x, pnmsg.Height)
    pnmsg.Visible = True
End Sub

Public Sub Say(msg As String, durance As Int)
    lbmsg.Text = msg
    pnmsg.RemoveView
    Caller.AddView(pnmsg, 10%x, 45%y, 80%x, pnmsg.Height)
    Sleep(durance)
    pnmsg.RemoveView
End Sub

And that's what happens in Main:

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Dim msg As Message
    Private Label1 As Label
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")
    msg.Initialize(Activity)
    msg.Say("Hello", 2000)
End Sub

Sub Label1_Click
    Dim mail As Email
    mail.To.Add("")
    mail.Subject = ""
    mail.Body = ""
    StartActivity(mail.GetIntent)
    msg.Say("Open Default Mail App", 2000)
End Sub

I am posting the example file for kind reviewing. It displays a Hello-message when started which disappears after two seconds, as expected. If you tap on 'Send mail' another message displays and will not be removed again when returning from the mail app. What can I do to prevent this from happening?
Thanks a lot

Sleep will not be resumed if the activity is paused.

Add an ActivityResume sub to your class:

Public Sub ActivityResume
 If pnlmsg.Parent <> Null Then pnlmsg.RemoveView
End Sub

Call it from the activity Activity_Resume sub.
