Apache FileUtils.MoveFile does not delete image after its been moved, device restart is required for the update to take place

Question

I'm using org.apache.commons.io.FileUtils to move files from one directory to another, like so:

File source = new File("/my/image/directory/image.jpg";
File destination = new File("/new/image/directory/image.jpg");
FileUtils.moveFile(source, destination);

Note that the source directory is an external directory and destination is an internal directory.

After above code is executed, I query to get the files of my internal directory like so:

File vaultDir = ctx.getDir("dir_name", Context.MODE_PRIVATE);
String[] fileList = vaultDir.list();
//Iterate and print file names

This is working as intended. But when i query the MediaStore like so:

ArrayList<GridViewObject> objects = new ArrayList<>();

String[] mProjection = {MediaStore.Images.Media.DISPLAY_NAME,
        MediaStore.Images.Media.DATA};

ContentResolver cr = ctx.getContentResolver();
Cursor mCursor = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
        mProjection,
        null,
        null,
        MediaStore.Images.Media.DEFAULT_SORT_ORDER);

mCursor.moveToFirst();
while (!mCursor.isAfterLast()) {
    GridViewObject tmpGridViewObject = new GridViewObject();
    tmpGridViewObject.setTitle(mCursor.getString(0));
    tmpGridViewObject.setUrl(mCursor.getString(1));
    objects.add(tmpGridViewObject);
    mCursor.moveToNext();
}

The image is still returned to me by the query. Also, when I open my camera gallery app, the image is still there, as if it was never deleted.

I noticed that if I restart the phone, the image disappears from my device camera gallery app as intended (and above query return correct result). So I think it might be an indexing problem.

What do I need to do to "update" the MediaStore to show the intended result?

I solved this by instead of deleting the file using FileUtils.delete(srcFile, destFile); i copied the the file using FileUtils.copy(srcFile, destFile); and then to refresh MediaStore i used the following code to delete the source entry:

String selection = MediaStore.Images.Media.DATA + "='" + source.getAbsolutePath() + "'";
ctx.getContentResolver().delete(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, selection, null);
