Hi Alberto: I try to make the loding kml files run in backgroud instead of opertion in manually,So I use the VectorGPEDriver loading several kml files.and it's work. The qusetion is how could I hide one of them in backgroud instead of opertion manually.I tried the function “driver.getOverlay().setVisible(false);” , But it's not work And loading the kml file cost so much time that the screen show black more then ten second. So ,how can we improve it. yours:lori
