　　　　<1>They are available to every Activity and Fragment.

　　　　<2>They provide asynchronous loading of data

　　　　<3>They monitor the source of their data and deliver new results when the content changes

　　　　<4>They automatically reconnect to the last loader‘s cursor when being recreated after a configuration change. Thus, they don‘t need to
