Change Volley timeout duration

Question

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

Answer 1

int MY_SOCKET_TIMEOUT_MS=500;

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

Answer 2

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));

Answer 3

/**
 * @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);
}
