Change Volley timeout duration

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));

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));
