Android Drawable.createFromStream分配了过多的内存

    HttpClient client = new DefaultHttpClient();
    HttpGet get = new HttpGet(url);

    HttpResponse response = client.execute(get);

    InputStream is = response.getEntity().getContent();

    Drawable drawable = Drawable.createFromStream(is, \"offers task\");

    return drawable;
