"The Wikitude plugin is a Phonegap plugin. Phonegap plugins add native files to your project (for Android: Java, for iOS: Obj-C). This native code supports functions that you can call from your hybrid code. Your hybrid code remains hybrid, but before deploying across platforms, you must provide a Phonegap plugin (such as the Wikitude plugin) for that platform. "
