what is the best way to fix the size of the disc based cache ??android -volley

Question

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

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

Few thoughts about Volley cache:

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.

I recommend you to play around this L1 cache for Volley

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();
