ImageLoader.getInstance().getDiscCache().get(imageUrl) returns different paths

问题

1. Call to cache

   ImageLoader.getInstance().loadImage(cnt, imageUrl, new ImageLoadingListener()

2. /mnt/sdcard/Android/data/[package]/cache/40d1dxbmdamufgcs742bjraew is created

3. ImageLoader.getInstance().getDiscCache().get(imageUrl) - returns /mnt/sdcard/Android/data/[package]/cache/40d1dxbmdamufgcs742bjraew -> OK

4. reboot device

5. ImageLoader.getInstance().getDiscCache().get(imageUrl) - returns /data/data/[package]/cache/40d1dxbmdamufgcs742bjraew -> KO (THIS FOLDER IS CREATED BUT ITS" EMPTY)
