Android Question B4XPages - Intercepting KeyPress

[epiCode]

How do I Implement the following code in B4XPages:

Sub Activity_KeyPress (KeyCode As Int) As Boolean

Select Keycode
    Case KeyCodes.KEYCODE_BACK
        'code to handle back key
    Case KeyCodes.KEYCODE_VOLUME_DOWN, KeyCodes.KEYCODE_VOLUME_UP
        'code to handle volume keys
    Case KeyCodes.KEYCODE_MEDIA_PLAY_PAUSE
        'code to handle media button
    Case Else
        Return False 'Pass to Android System
End Select

Change the Activity_KeyPress code to:

Sub Activity_KeyPress (KeyCode As Int) As Boolean
    If KeyCode = KeyCodes.KEYCODE_BACK Then
        Return B4XPages.Delegate.Activity_KeyPress(KeyCode)
    End If
    B4XPages.GetManager.RaiseEvent(B4XPages.GetManager.GetTopPage, "B4XPage_KeyPress", Array(KeyCode))
    Return False
End Sub

And implement B4XPage_KeyPress in the relevant pages.
The back key will be handled in the CloseRequest event sub.
