Use conditional class loading. Put all your NFC-specific code in a class that you refer to *if and only if* you are on a suitable device. Having the code referring to a newer API Level is fine, so long as you never try running it on an older device. For example, in this sample project, I use a HoneycombHelper class to isolate getActionView(), to allow me to add custom widgets to the action bar on Honeycomb but still work on older devices: https://github.com/commonsguy/cw-android/tree/master/Menus/ActionBarBC -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 3.6 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
