+/**
+ * <p>A LiveFolder is a special folder whose content is provided by a
+ * {@link android.content.ContentProvider}. To create a live folder, two components
+ * are required:</p>
+ * <ul>
+ *  <li>An activity that can respond to the intent action {@link #ACTION_CREATE_LIVE_FOLDER}. The
+ *  activity is responsible for creating the live folder.</li>
+ *  <li>A {@link android.content.ContentProvider} to provide the live folder items.</li>
+ * </ul>
+ *
+ * <h3>Lifecycle</h3>
+ * <p>When a user wants to create a live folder, the system looks for all activities with the
+ * intent filter action {@link #ACTION_CREATE_LIVE_FOLDER} and presents the list to the user.
+ * When the user chooses one of the activities, the activity is invoked with the
+ * {@link #ACTION_CREATE_LIVE_FOLDER} action. The activity then creates the live folder and
+ * passes it back to the system by setting it as an
+ * {@link android.app.Activity#setResult(int, android.content.Intent) activity result}. The
+ * live folder is described by a content provider URI, a name, an icon and a display mode.
+ * Finally, when the user opens the live folder, the system queries the content provider
+ * to retrieve the folder's content.</p>
+ *
+ * <h3>Setting up the live folder activity</h3>
+ * <p>The following code sample shows how to write an activity that creates a live folder:</p>
+ * <pre>
+ * public static class MyLiveFolder extends Activity {
+ *     public static final Uri CONTENT_URI = Uri.parse("content://my.app/live");
+ *
+ *     protected void onCreate(Bundle savedInstanceState) {
+ *         super.onCreate(savedInstanceState);
+ *
+ *         final Intent intent = getIntent();
+ *         final String action = intent.getAction();
+ *
+ *         if (LiveFolders.ACTION_CREATE_LIVE_FOLDER.equals(action)) {
+ *             setResult(RESULT_OK, createLiveFolder(this, CONTENT_URI, "My LiveFolder",
+ *                     R.drawable.ic_launcher_contacts_phones));
+ *         } else {
+ *             setResult(RESULT_CANCELED);
+ *         }
+ *
+ *         finish();
+ *     }
+ *
+ *     private static Intent createLiveFolder(Context context, Uri uri, String name,
+ *             int icon) {
+ *
+ *         final Intent intent = new Intent();
+ *
+ *         intent.setData(uri);
+ *         intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_NAME, name);
+ *         intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_ICON,
+ *                 Intent.ShortcutIconResource.fromContext(context, icon));
+ *         intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_DISPLAY_MODE, LiveFolders.DISPLAY_MODE_LIST);
+ *
+ *         return intent;
+ *     }
+ * }
+ * </pre>
+ * <p>The live folder is described by an {@link android.content.Intent} as follows:</p>
+ * <table border="2" width="85%" align="center" frame="hsides" rules="rows">
+ *     <thead>
+ *     <tr><th>Component</th> <th>Type</th> <th>Description</th> <th>Required</th></tr>

+ * <h3>Setting up the content provider</h3>
+ * <p>The live folder's content provider must, upon query, return a {@link android.database.Cursor}
+ * whose columns match the following names:</p>
+ * <table border="2" width="85%" align="center" frame="hsides" rules="rows">
+ *     <thead>
