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));
