推荐答案

而现在的警句：使用系统缓存

And now the punchline: use the system cache.

URL url = new URL(strUrl);
URLConnection connection = url.openConnection();
connection.setUseCaches(true);
Object response = connection.getContent();
if (response instanceof Bitmap) {
  Bitmap bitmap = (Bitmap)response;
} 

同时提供内存和闪存-ROM缓存，与浏览器共享。

Provides both memory and flash-rom cache, shared with the browser.

GRR。我希望有人告诉我，以前我写我自己的高速缓存管理器。

grr. I wish somebody had told ME that before i wrote my own cache manager.
