Exit application

[fatman]

Hi folks,

I am developing an app containing a shopping cart and the items are stored in sqlite tables.

I have the following question:
What happens if the user is pressing the home button by chance? To my mind Android closes the app and thats it.
Creating a mess with an order not finished... etc.
In my windows applications I have a button like "Do you want to exit application (yes/no)?" making sure the user is taking this "exit" only.

How can I implement this in my android app resulting a proper end of my app?

Any hints are welcome!

Have a look at the Beginner's Guide chapter 18.6 Avoid closing an application.

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the
event
  Dim Answ As Int
  If KeyCode = KeyCodes.KEYCODE_BACK Then
    Answ = Msgbox2("Do you want to quit the program", _
      "A T T E N T I O N", "Yes", "", "No", Null)
    If Answ = DialogResponse.NEGATIVE Then
      Return True
    End If
  End If
  Return False
End Sub

Best regards.

Pressing Home does not automatically close the app. See Tricks Of The Trade - Basic4android Wiki.
