Notify mediastore to scan a file:

private void scanSingleFile(String filePath) {        if (filePath == null) {            return;        }// broadcast to scan file        boolean bmnt = Environment.getExternalStorageDirectory().getPath()                .startsWith("/mnt");        bmnt = mDownloadDestination                .equalsIgnoreCase(UpDownloadUtils.DOWNLOAD_DEST_SDCARD) ? bmnt                : false;        File file = new File(bmnt ? ("/mnt" + filePath) : filePath);        MediaScannerConnection.scanFile(mContext,                new String[] { file.toString() }, null,                new MediaScannerConnection.OnScanCompletedListener() {                    @Override                    public void onScanCompleted(String path, Uri uri) {                                            ContentResolver cr = mContext.getContentResolver();                        long datemodified = 0;                        long dateadded = 0;                        Cursor cursor = cr.query(uri, null, null, null, null);                        if (cursor != null && cursor.moveToFirst()) {                            datemodified = cursor.getLong(cursor                                    .getColumnIndex(MediaStore.MediaColumns.DATE_MODIFIED));                            dateadded = cursor.getLong(cursor                                    .getColumnIndex(MediaStore.MediaColumns.DATE_ADDED));                            cursor.close();                        }                        ContentValues values = new ContentValues();                        if (datemodified > 0                                && String.valueOf(datemodified).length() > 10) {                            values.put(MediaStore.MediaColumns.DATE_MODIFIED,                                    datemodified / 1000);                        }                        if (dateadded > 0                                && String.valueOf(dateadded).length() > 13) {                            values.put(MediaStore.MediaColumns.DATE_ADDED,                                    dateadded / 1000);                        }                        if (values.size() > 0) {                            cr.update(uri, values, null, null);                        }                    }                });    }
