What is "android-loader"

The Loaders have the following characteristics::

1. Are available throughout Activity and Fragment.
2. They provide asynchronous data loading.
3. They monitor the data source and deliver new results as content changes.
4. Automatically reconnect to the last Cursor* when they are recreated after a configuration change. With this, they do not need to query the data again.

*Only for CursorLoader.
