How to retrieve images from cache memory?

How to retrieve images from cache memory?



I am using picasso library for loading images .In default picasso, It uses

internal cache memory for loading images.But as per my app configuration

,i have to use external cache memory(Cache on Disk). so i used this code

for Cache on Disk

File httpCacheDir = new

File(getApplicationContext().getExternalCacheDir(),"http");

long httpCacheSize = 10 * 1024 * 1024; // 10 MiB

HttpResponseCache.install(httpCacheDir, httpCacheSize);}

Picasso is flexible. So now it caches images in external Sd card..

The caches is stored in sdcard/android/data/packagename/cache/http The

caches are stored in ".1" ,".0". formats so i just opened them and changes

into ".1" to ".jpg".it gives exact images what i need. But how to do in

programatically? but picasso itself caches my memory in to my app for

loading image into imageview.but i have to download images from cache

memory..any help?
