how to update gallery after moving photo programmatically?

问题

I am moving photo from on directory to another using following code

File oldfile= new File(originalImagePath);              
File newfile=new File(newImagePath);
boolean d=oldfile.renameTo(newfilee);
if(d){

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + newfilee.getPath())));
 }

photos moved to new directory successfully but it take too long time when photos are more in count to update gallery and gallery updates after around 30 seconds or more So give me suggestion what I should do if logic to update file using sendBroadcast is wrong?

Thanks.

if (Build.VERSION.SDK_INT < 19)
    mContext.sendBroadcast(new Intent(
            Intent.ACTION_MEDIA_MOUNTED,
            Uri.parse("file://"
                    + Environment.getExternalStorageDirectory())));
else {
    MediaScannerConnection
            .scanFile(
                    mContext,
                    new String[]{imageFile.toString()},
                    null,
                    new MediaScannerConnection.OnScanCompletedListener() {
                        public void onScanCompleted(
                                String path, Uri uri) {
                            Log.i("ExternalStorage", "Scanned "
                                    + path + ":");
                            Log.i("ExternalStorage", "-> uri="
                                    + uri);
                        }
                    });
}
