We use picaaso to download images in background for our android application.
But we found that when I killed my application 3 times, the picasso cache was cleared automatically.

So I do some research for this appearances, and I found that the problem is about DiskLruCache.class.
In this class, it created a file called "journal" in picasso-cache directory. The file recorded every image file name, just as follow:

journal example: ------------


libcore.io.DiskLruCache
