public Fragment ();- Attributes
Remarks
Default constructor. <strong>Every</strong> fragment must have an empty constructor, so it can be instantiated when restoring its activity's state. It is strongly recommended that subclasses do not have other constructors with parameters, since these constructors will not be called when the fragment is re-instantiated; instead, arguments can be supplied by the caller with #setArguments and later retrieved by the Fragment with #getArguments.
Applications should generally not implement a constructor. Prefer #onAttach(Context) instead. It is the first place application code can run where the fragment is ready to be used - the point where the fragment is actually associated with its context. Some applications may also want to implement #onInflate to retrieve attributes from a layout resource, although note this happens when the fragment is attached.
