Android : Adding image to gallery in Android

I have an app which does two things :

• it captures photo by camera app and saves it to gallery - and this works


• generates .gif out of images and saves it in ExternalStoragePublicDirectory - and this doesn't work

This is the method I am using to add file to gallery :

public static void galleryAddPic(Context context, String currentPhotoPath) {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(currentPhotoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    context.sendBroadcast(mediaScanIntent);
}

I have read somewhere that this doesn't work on Android Api 19, can anybody confirm? Is there any better solution for adding picture to gallery than my above method? Cheers
