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
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));
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.
I ended up adding a method setCurrentTimeout(int timeout)
to the RetryPolicy
and it's implementation in DefaultRetryPolicy
.
Then I added a setCurrentTimeout(int timeout)
in the Request class and called it .
This seems to do the job.
Sorry for my laziness by the way and hooray for open source.
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.
Alternative solution if all above solutions are not working for you
By default, Volley set timeout equally for both setConnectionTimeout()
and setReadTimeout()
with the value from RetryPolicy
. In my case, Volley
throws timeout exception for large data chunk see:
com.android.volley.toolbox.HurlStack.openConnection().
My solution is create a class which extends HttpStack
with my own setReadTimeout()
policy. Then use it when creates RequestQueue
as follow:
Volley.newRequestQueue(mContext.getApplicationContext(), new MyHurlStack())
Another way of doing it is in custom JsonObjectRequest by:
@Override
public RetryPolicy getRetryPolicy() {
// here you can write a custom retry policy and return it
return super.getRetryPolicy();
}
