Change Volley timeout duration

I use the new Volley framework for Android to do a request to my server. But it timeouts before getting the response, although it does respond.

I tried adding this code:

HttpConnectionParams.setConnectionTimeout(httpParams, 5000);
HttpConnectionParams.setSoTimeout(httpParams, timeoutMs);

in HttpClientStack of the Volley framework to a different integer (50000), but it still times out before 50 seconds.

Is there a way to change the timeout to a long value?

See Request.setRetryPolicy() and the constructor for DefaultRetryPolicy, e.g.

JsonObjectRequest myRequest = new JsonObjectRequest(Method.GET,
        url, null,
        new Response.Listener<JSONObject>() {

            @Override
            public void onResponse(JSONObject response) {
                Log.d(TAG, response.toString());
            }
        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                Log.d(TAG, "Error: " + error.getMessage());
            }
});

myRequest.setRetryPolicy(new DefaultRetryPolicy(
        MY_SOCKET_TIMEOUT_MS, 
        DefaultRetryPolicy.DEFAULT_MAX_RETRIES, 
        DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

To handle Android Volley Timeout you need to use RetryPolicy

RetryPolicy

• Volley provides an easy way to implement your RetryPolicy for your requests.
• Volley sets default Socket & ConnectionTImeout to 5 secs for all requests.

RetryPolicy is an interface where you need to implement your logic of how you want to retry a particular request when a timeout happens.

It deals with these three parameters

• Timeout - Specifies Socket Timeout in millis per every retry attempt.
• Number Of Retries - Number of times retry is attempted.
• Back Off Multiplier - A multiplier which is used to determine exponential time set to socket for every retry attempt.

For ex. If RetryPolicy is created with these values

Timeout - 3000 ms, Num of Retry Attempts - 2, Back Off Multiplier - 2.0

Retry Attempt 1:

• time = time + (time * Back Off Multiplier);
• time = 3000 + 6000 = 9000ms
• Socket Timeout = time;
• Request dispatched with Socket Timeout of 9 Secs

Retry Attempt 2:

• time = time + (time * Back Off Multiplier);
• time = 9000 + 18000 = 27000ms
• Socket Timeout = time;
• Request dispatched with Socket Timeout of 27 Secs

So at the end of Retry Attempt 2 if still Socket Timeout happens Volley would throw a TimeoutError in your UI Error response handler.

//Set a retry policy in case of SocketTimeout & ConnectionTimeout Exceptions. 
//Volley does retry for you if you have specified the policy.
jsonObjRequest.setRetryPolicy(new DefaultRetryPolicy(5000, 
                DefaultRetryPolicy.DEFAULT_MAX_RETRIES, 
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

Just to contribute with my approach. As already answered, RetryPolicy is the way to go. But if you need a policy different the than default for all your requests, you can set it in a base Request class, so you don't need to set the policy for all the instances of your requests.

Something like this:

public class BaseRequest<T> extends Request<T> {

    public BaseRequest(int method, String url, Response.ErrorListener listener) {
        super(method, url, listener);
        setRetryPolicy(getMyOwnDefaultRetryPolicy());
    }
}

In my case I have a GsonRequest which extends from this BaseRequest, so I don't run the risk of forgetting to set the policy for an specific request and you can still override it if some specific request requires to.

/**
 * @param request
 * @param <T>
 */
public <T> void addToRequestQueue(Request<T> request) {

    request.setRetryPolicy(new DefaultRetryPolicy(
            MY_SOCKET_TIMEOUT_MS,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

    getRequestQueue().add(request);
}

req.setRetryPolicy(new DefaultRetryPolicy(
    MY_SOCKET_TIMEOUT_MS, 
    DefaultRetryPolicy.DEFAULT_MAX_RETRIES, 
    DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

You can set MY_SOCKET_TIMEOUT_MS as 100. Whatever you want to set this to is in milliseconds. DEFAULT_MAX_RETRIES can be 0 default is 1.
