To save the conversation, maybe you could start with this:

Sub Activity_Pause (UserClosed As Boolean)
    If UserClosed Then
        <save your conversation here>
    End If
End Sub

Sub Activity_Resume
    <restore your conversation here>
End Sub

To delete some conversation, you can improve this code:

Chat.bas:

Private Sub AddItem (Text As String, Right As Boolean)
    Dim p As B4XView = xui.CreatePanel("pnl")  'CODE CHANGE: insert the eventName = "pnl"
    (...)   
End Sub

Sub pnl_LongClick
'CODE CHANGE: remove the panel with conversation using a long click
    Dim pn As Panel = Sender
    pn.RemoveView
End Sub
