Locate the ''res -> layout -> main.xml'' file and double click on it to load it into the main panel. Select the TextView object in the user interface layout and delete it.
Next, select the Advanced section of the Palette and drag and drop a GestureOverlayView object onto the Layout canvas and resize it to fill the entire layout area. Change the ID of the GestureOverlayView object to gOverlay. When completed, the ''main.xml '' file should read as follows:
