    As per Saving cache files from the Android developer, use Context.getExternalCacheDir() (API level 8) or Environment.getExternalStorageDirectory() + /Android/data/<package_name>/cache/ (API level 7 or lower) as the location to store cache files.

    If you have different caches, add a subdirectory for each.

    Both of the above approaches are in your app’s “private” data space and will be removed along with your app — that’s a good thing, you don’t want to use space on a device when your app is gone.

    Also, don’t use the URL direclty as file name, create a digest/hash of it and use that, like the iosched app does. This spares you from escaping any special characters in the URL yourself.
