You are not using the right implementations of <code>CursorLoader</code> and <code>Loader</code>.
Remove your old imports and use these ones:

<pre><code>import android.support.v4.app.LoaderManager;
import android.support.v4.content.CursorLoader;
import android.support.v4.content.Loader;
import android.support.v4.widget.CursorAdapter;
</code></pre>

But I have the same Problem using SherlockActionBar:
As I have to extend <code>SherlockListActivity</code> there is NO method <code>getSupportLoadManager()</code>.

Any ideas on this?

EDIT: follow <a href="http://code.tutsplus.com/tutorials/android-sdk_fragments--mobile-5367/" rel="noreferrer" title="Android User Interface Design: Working With Fragments">this tutorial</a> if you do not know how to use fragments. Create a new Class with extends SherlockFragment and move your display logic there. Make your old activity extend SherlockFragmentActivity and show the newly created SherlockFragment. This way I got it working. Thanks to @JakeWharton!

I'm using ActionBarSherlock with my app and I as well was running into this issue and worked through all the steps discussed by others in this question. However I was continuing to have the same problem after trying all the suggested resolutions. 

<pre><code>The method initLoader(int, Bundle, LoaderManager.LoaderCallbacks&lt;D&gt;) in the type LoaderManager is not applicable for the arguments (int, null, this)
</code></pre>

The issue was I had fallen into expecting Eclipse to tell me when I was missing something and it was telling me that but not in the way I was used to. Typically Eclipse in other cases would tell me I'm missing the overrides to make something work but it's not directly saying that here. I finally picked up on the "LoaderManager.LoaderCallbacks" being the issue and realized I had no callbacks for it thus this error was actually a very valid error. Adding the basic overrides resolved my issue and allowed me to move forward.

<pre><code>// Creates a new loader after the initLoader () call
@Override
public Loader&lt;Cursor&gt; onCreateLoader(int id, Bundle args) {
 // do work
 return null;
}

@Override
public void onLoadFinished(Loader&lt;Cursor&gt; loader, Cursor data) {
 adapter.swapCursor(data);
}

@Override
public void onLoaderReset(Loader&lt;Cursor&gt; loader) {
 // data is not available anymore, delete reference
 adapter.swapCursor(null);
}
</code></pre>

Ran into the same problem. My minSdkVersion is 14, so cannot use android.support.v4 package.

I figured it by extending LoaderCallbacks, instead of LoaderManager.LoaderCallbacks and use these packages

import android.widget.SimpleCursorAdapter;

if you use loader maneger in fragment and you min api is below HONEYCOMB 
you shuld use this imports

import android.support.v4.content.Loader;

I'm having trouble following a <a href="http://www.vogella.com/articles/AndroidSQLite/article.html">guide</a> on using SQLite in Android. I'm using a <code>ListFragment</code> instead of a <code>ListActivity</code>(as in the example), so I have the <code>ListFragment</code> implement <code>LoaderManager.LoaderCallbacks&lt;Cursor&gt;</code> instead. Then, in the <code>fillData()</code> method in the <code>ListFragment</code>:

 // Fields from the database (projection)
 // Must include the _id column for the adapter to work
 String[] from = new String[] { NotesSQLiteHelper.COLUMN_TITLE };
 // Fields on the UI to which we map
 int[] to = new int[] { R.id.label };

 getLoaderManager().initLoader(0, null, this); //error
 adapter = new SimpleCursorAdapter(getApplicationContext(), R.layout.notes_row, null, from, to, 0);
 setListAdapter(adapter);
}

I get the error:

<pre><code>The method initLoader(int, Bundle, LoaderManager.LoaderCallbacks&lt;D&gt;) in the type LoaderManager is not applicable for the arguments (int, null, NotesActivity.ArrayListFragment)
