Support Disk Cache Warming

See original GitHub issue

fetch() with no callback coupled with skipCache(). Should not do any bitmap decoding and it should abandon the hold on the connection as soon as possible.

Any update to this issue? I need to pre-fetch about 500 images and fetch() is unnecessarily decoding each one. Also, it appears that skipCache() has been replaced by something else. Not sure what though.

I’ve had a root around and it looks like adding:

  if (action instanceof FetchAction) {
    InputStream is = result.getStream();
    Utils.closeQuietly(is);
    return(null);
  }

to BitmapHunter.hunt() before decodeStream() is called does the trick. Memory usage and device load during cache warming (many calls to fetch()) is much lower and the http cache is filled as before.

What might I be missing?
