I want to use the DiskLruCache 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 )
I found no method to get the Value of this Snapshot Object.
Thanks for every help.

The DiskLruCache opens a stream to a particular location in the directory. For example, for getting a stream at index 0( remember we can save multiple values for a particular key), and converting it to BufferedStream for writing data, we use. OutputStream out = new BufferedOutputStream(editor.
A disk cache can be used in these cases to persist processed bitmaps and help decrease loading times where images are no longer available in a memory cache. Of course, fetching images from disk is slower than loading from memory and should be done in a background thread, as disk read times can be unpredictable.
LruCache . Used to write apps that run on API levels prior to 12. When running on API level 12 or above, this implementation is still used; it does not try to switch to the framework's implementation. See the framework SDK documentation for a class overview.
I used getBitmap() in the sample someone posted here.
This is the answer you're looking for under a different title. You will have to create a Utils for some of the code but it's pretty straightforward.
Good Luck!
Using DiskLruCache in android 4.0 does not provide for openCache method
