I think you should run MediaScanner http://stackoverflow.com/questions/13270789/how-to-run-media-scanner-in-android like this but I don't really remember the details — Alexander Kulyakhtin, May 18 '16 at 06:37

Just you need to write a method for delete file and replace the code file.delete(); with deleteFileFromMediaStore(this.getContentResolver(),file);

    public  void deleteFileFromMediaStore(final ContentResolver contentResolver, final File file) {
    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});
        }
    }
}

It works for android 5.0. But its not working for android 6.0 — hasnain_ahmad, Jun 08 '16 at 06:16
