Android: Refreshing the Gallery after saving new images

Code provided by Petrus in another answer works for me on Kitkat (4.4):

MediaScannerConnection.scanFile(this, new String[] { Environment.getExternalStorageDirectory().toString() }, null, new MediaScannerConnection.OnScanCompletedListener() {
/*
 *   (non-Javadoc)
 * @see android.media.MediaScannerConnection.OnScanCompletedListener#onScanCompleted(java.lang.String, android.net.Uri)
 */
public void onScanCompleted(String path, Uri uri) 
  {
      Log.i("ExternalStorage", "Scanned " + path + ":");
      Log.i("ExternalStorage", "-> uri=" + uri);
  }
    });

You should delete it from mediaStore

    String canonicalPath;
    try {
        canonicalPath = file.getCanonicalPath();
    } catch (IOException e) {
        canonicalPath = file.getAbsolutePath();
    }
    final Uri uri = MediaStore.Files.getContentUri("external");
    final int result = contentResolver.delete(uri,
            MediaStore.Files.FileColumns.DATA + "=?", new String[] {canonicalPath});
    if (result == 0) {
        final String absolutePath = file.getAbsolutePath();
        if (!absolutePath.equals(canonicalPath)) {
            contentResolver.delete(uri,
                    MediaStore.Files.FileColumns.DATA + "=?", new String[]{absolutePath});
