 * <h3>Installing an HTTP response cache</h3>

 * Enable caching of all of your application's HTTP requests by installing the

 * cache at application startup. For example, this code installs a 10 MiB cache

 * in the {@link android.content.Context#getCacheDir() application-specific cache directory} of

 * the filesystem}: <pre>   {@code

 * in the {@link android.content.Context#getCacheDir() application-specific

 * cache directory} of the filesystem}: <pre>   {@code

 *   protected void onCreate(Bundle savedInstanceState) {

 *       ...

 *

 * contain private data.</strong> Although it often has more free space,

 * external storage is optional and—even if available—can disappear

 * during use. Retrieve the external cache directory using {@link

 * Context#getExternalCacheDir()}. If this method returns null, your application

 * should fall back to either not caching or caching on non-external storage. If

 * the external storage is removed during use, the cache hit rate will drop to

 * zero and ongoing cache reads will fail.
