Usage

From source file:com.demo.weather.sunshine.ForecastFragment.java

@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    // This is called when a new Loader needs to be created.  This
    // fragment only uses one loader, so we don't care about checking the id.

    // To only show current and future dates, get the String representation for today,
    // and filter the query to return weather only for dates after or including today.
    // Only return data after today.
    String startDate = WeatherContract.getDbDateString(new Date());
    // Sort order:  Ascending, by date.
    String sortOrder = WeatherEntry.COLUMN_DATETEXT + " ASC";

    mLocation = Utility.getPreferredLocation(getActivity());

    // Now create and return a CursorLoader that will take care of
    // creating a Cursor for the data being displayed.
