http://stackoverflow.com – Hello i'm developing a android application which uses a html webview "virtual tour" this runs very smooth op ipad and iphones but on android devices it runs very badly only the newer ones like samsung galaxy 3 and htcs it will run smooth. Now my question is it possible to show a button on some android devices and not show a button on let say older devices. Many thanks already! (HowTos)
