Force refresh Gallery app on Android 4.4

I have an application that handles images, in it has options to move and delete images, when I delete an image is sent a boradcast so that the android gallery application recognize that the image is no longer there. Is working perfectly, except for Android 4.4!

I’m wearing it like this:

public void forceMediaScan(String path){
        File f1 = new File(path);
        Intent scanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
        scanIntent.setData(Uri.fromFile(f1));
        getActivity().sendBroadcast(scanIntent);
}

I’ve searched and tried to use scanFile, but it doesn’t work, the Gallery application of Android 4.4 does not recognize the change

MediaScannerConnection.scanFile(getActivity(), new String[]{path}, null,null);

I have tried using scanFile for a specific file and for an entire path (which is the case for the example), but it does not work.

I found the answer. the media scan does not accept a Folder as path, has to image by image in a String array, only so use scanFile.

inside the path through the folder:

MediaScannerConnection.scanFile(getActivity(), new String[]{aFile.getAbsolutePath()}, null,null);

Note that I used getAbsolutePath() to take the full path.

Do not use sendBoradcast for this purpose! scanFile serves for this, and is much faster in this case.
