CursorLoader does not update after notification

Question

I registered CursorLoaderbut not receiving updates from myContentProvider

Sequence of events:

• In a Fragmentregister CursorLoader with:

  getLoaderManager().initLoader(LOADER_FAVS_ID, null, this);
  

  Note. I am using the support library version, so this methodandroid.support.v4.app.Fragment.getLoaderManager()

• It is registered CursorLoader, and Cursorloaded into onLoadFinished:

  @Override
  public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
          Log.i(TAG, "onLoadFinished");
          switch (loader.getId()) {
          case LOADER_FAVS_ID:
                  Log.i(TAG,
                                  "cursor notification uri: " + cursor.getNotificationUri());
                  mCursorAdapter.swapCursor(cursor);
                  break;
          }
  }
  

  What magazines cursor notification uri: content://com.myapp.mylocation/db_locations, for example. This is because I definitely called cursor.setNotificationUri(getContext().getContentResolver(), uri);before returning the cursor from my ContentProvider. Also note that my content provider is returning MergeCursor.

• After some time, the call is made to update()in mine ContentProvider, and the following lines are executed:

  Log.i(TAG,
          "Notifying uri: " + uri.toString());
  getContext().getContentResolver().notifyChange(
          uri, null);
  

  Which logs Notifying loc uri: content://com.myapp.mylocation/db_locationsare the same uri as above.

MergeCursor ContentProvider, .

    @Override
    public Cursor query(Uri uri, String[] projection, String selection,
                    String[] selectionArgs, String sortOrder) {
            // Generate an array of Cursors

            MergeCursor mergCursor = new MergeCursor(cursorArray);

            // notify potential listeners
            mergCursor.setNotificationUri(getContext().getContentResolver(), uri);

            return mergCursor;
    }

CursorLoader . , MergeCursor Cursor, uri MergeCursor.

    @Override
    public Cursor query(Uri uri, String[] projection, String selection,
                    String[] selectionArgs, String sortOrder) {
            // Generate an array of Cursors

            // set the notification uris...
            for (Cursor cursor : cursorArray) {
                    cursor.setNotificationUri(getContext().getContentResolver(), uri);
            }

            MergeCursor mergCursor = new MergeCursor(cursorArray);

            return mergCursor;
    }
