What Is The Maximum Size Of The Volley-library Request-queue

I am using Volley library in Android, I want to know what is maximum size of queue is allowed using Volley library. There is nothing I found related to this. As I know you need to

Solution 1:

You are probably confusing 2 things:

• wating queue size
• max parallel network requests

For waiting queue size:

/** The queue of requests that are actually going out to the network. */privatefinalPriorityBlockingQueue<Request<?>> mNetworkQueue =
    new PriorityBlockingQueue<Request<?>>();

Volley uses a PriorityBlockingQueue which itself uses a PriorityQueue with a initial capacity of 11, but will automatically grow, so there should be no reasonable limit.

privatestatic final int DEFAULT_INITIAL_CAPACITY = 11;
...
publicPriorityQueue() {
    this(DEFAULT_INITIAL_CAPACITY, null);
}

For max parallel network requests:

RequestQueuerequestQueue= Volley.newRequestQueue(this);

will call

RequestQueue queue = newRequestQueue(newDiskBasedCache(cacheDir), network);

and this calls

public RequestQueue(Cache cache, Network network) {
        this(cache, network, DEFAULT_NETWORK_THREAD_POOL_SIZE);
    }

and DEFAULT_NETWORK_THREAD_POOL_SIZE is

privatestaticfinalint DEFAULT_NETWORK_THREAD_POOL_SIZE = 4;

So by default there are 4 concurrent threads handling the requests (so max 4 request at the same time).

---

Waiting queue size is Integer.MAX ie. basically limitless; while max parallel network requests are 4, which can be changed with the RequestQueue constructor.
