title: Example of JakeWhartons DiskLruCache
body: <p>I want to use the <code>DiskLruCache</code> from Jake Wharton in my Android app based on API Level 7+. I would use it in my ListView to Cache downloaded images on SdCard but i didn't understood the usage of this library.
  Can anybody show me a example of how to get Bitmaps from this Cache or put Bitmaps in the cache? ( key = filePath, value = Bitmap )</p>
  
  <p>I found no method to get the Value of this Snapshot Object.</p>
  
  <p>Thanks for every help.</p>
