Caching bitmap Android

What is the best way of caching Bitmaps if my min sdk is api lvl 8? I have a downloaded Bitmap which I would like to save, I can also get a type of hash for the image. Is it OK to just write it to a normal file anywhere if i fix the permissions, say like this? 

FileOutputStream fOut = new FileOutputStream(file);

bmp.compress(Bitmap.CompressFormat.PNG, 85, fOut);

I think you should use Universal Image Loader library. It will do the caching, loading from url and other things by itself.

One of the best way to download and cache images is use Volley library. It's really easy and comfortable. There are a lot of different examples in the Internet but at first I suggest you to watch IO video . And then look for code examples (BitmapLruCache - is used directly for caching) (e.g. here or here)
