修复基于光盘的缓存大小的最佳方法是什么?android -volley [英] what is the best way to fix the size of the disc based cache ??android -volley

问题描述

1)android -volley中基于磁盘的缓存的默认实现被分配了5MB的总内存.

1)The default implementation of the disc based cache present in android -volley is allocated a total memory of 5MB .

2)但是Iam开发的应用程序包含很多图像.因此，我想增加基于磁盘的缓存分配的内存大小.

2)But the app Iam developing contains a lot of images .So I want to increase the size of the memory allocated by disc based cache .

3)因此，我想增加缓存的大小..我可以通过更改Diskbasedcache.java文件中的DEFAULT_DISK_USAGE_BYTES的值来简单地做到这一点.

3)So I want to increase the size of the cache ..I can simple do it by changing the value of DEFAULT_DISK_USAGE_BYTES inside Diskbasedcache.java file .

4)但是我想根据光盘上的可用空间分配内存?有什么方法可以实现它?

4)But I want to allocate memory based on the amount of space available in the disc ???Is there any way to implement it ??

推荐答案

关于Volley缓存的一些想法:

Few thoughts about Volley cache:

使用基于磁盘的L1缓存可能会导致I/O阻塞问题. Volley已经具有隐式磁盘L2高速缓存. BitmapLruImageCache 是内存缓存实现中的基本最近最少使用".它速度很快，并且不会阻止I/O.这是推荐的方法.

Using a disk based L1 cache may cause i/o blocking issues. Volley already has an implicit disk L2 cache. BitmapLruImageCache is a basic "least recently used" in memory cache implementation. It is fast and does not block I/O. This is the recommended approach.

我建议您使用此 Volley的L1缓存

要调整大小，请看以下内容:

for tweaking the size have a look at this:

RequestQueue volleyQueue = Volley.newRequestQueue(this);
DiskBasedCache cache = new DiskBasedCache(getCacheDir(), 16 * 1024 * 1024);
volleyQueue = new RequestQueue(cache, new BasicNetwork(new HurlStack()));
volleyQueue.start();
