If you browse an online store and add a bunch of things to a shopping list, that's saved using a cookie. Cookies also keep track of which site you're logged in to—which is why, if you clear your cookies, you'll need to log back in to all of your accounts. Clearing your cache doesn't affect any of this. Related, but not exactly the same: you can visit the cached version of many websites through Google search. Instead of bringing you to the live website, it'll show you the page the last time Google's robots visited it.
Here's how —along with lots of other Google search tricks. In general, I recommend not clearing your cache unless you have a specific reason to. The files in the cache allow the websites you visit most often to load faster, which is a good thing.
Your browser will periodically delete old files, so it's not like the cache is going to keep growing forever. Sure, the cache is taking up room on your hard drive, and some people find that annoying. But the reason you have a hard drive is so you can store things on it, and a cache that speeds up your web browsing feels like a valid use of your hard drive's space.

To download an image and save to the memory card you can do it like this. Ljdawson Ljdawson Why are you decoding the JPEG and then re-encoding it? You are better served downloading the URL to a byte array, then using that byte array to create your Bitmap and write out to a File.
Every time you decode and re-encode a JPEG, the image quality gets worse. Fair point, was more for speed then anything. Although, if saved as a byte array and the source file was not a JPEG wouldn't the file need to be converted anyways? Show 2 more comments.
