Android : Can't set GlideBuilder

I use Glide library for Android. I want set cache in my custom folder, becouse standart cache folder can be clean (with Master Clean for example). So I use this code from manual, but this don't work for me.

My code:

DiskCache.Factory diskCacheFactory = new DiskCache.Factory() {
            @Override
            public DiskCache build() {
                DiskCache diskCache = DiskLruCacheWrapper.get(getFilesDir(), 1024*1024*100);
                return diskCache;
            }
        };
        new GlideBuilder(this).setDiskCache(diskCacheFactory);
        Glide.with(this)
                .load("http://www.website.com/1.jpg")
                .into(imageView);

And after I run this app Glide save image in default folder.
