You can do it with this code:

B4X:

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the event
   If KeyCode = KeyCodes.KEYCODE_BACK Then
     HandleBackKey 
     Return True 
   End If
   Return False
End Sub

Private Sub HandleBackKey
  Msgbox2Async(Message, "Close?", "Yes", "No", "", Null, False)
   Wait For MsgBox_Result (Result As Int)
   If Result = DialogResponse.POSITIVE Then
     Activity.Finish
   End If
End Sub

It is better than showing a modal dialog in the KeyPress event.
