10. Adobe AIR With most platforms, you’re exporting an AIR application AIR app is “wrapped” with a native installer (i.e. APK file) Application is installed If user doesn’t have AIR, they will be prompt to download AIR app is then installed iOS is the only exception App is converted to a NATIVEiOS application because iOS does not support Adobe AIR
