On screen rotation the fragment is automatically destroyed and re-created, and to do that Android uses the default constructor (public with no parameters). Nevertheless, the arguments will be saved and retrieved from the operating system if these have been set by the method
With the Android Fragment Code Generator tool you can generate in few seconds the necessary code to successfully implement a fragment, without having to worry too much of the aspects mentioned above.
