Android Volley double post when have slow request

Question

I have a problem with Volley POST request on slow network. Everytime I see BasicNetwork.logSlowRequests in my LogCat, my POST request is executed twice or more

Answer 1

please increase the setRetryPolicy time.

request.setRetryPolicy(new DefaultRetryPolicy(
                    30000,
                    DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                    DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
            Volley.newRequestQueue(this).add(equest);

Answer 2

Just setting the Timeout in the RetryPolicy to 0 is too little. After checking the source, you have to actually set the maximum number of retries < 0, as it is checking current <= max...

I fixed double posting with setting the policy to the following

new DefaultRetryPolicy(0, -1, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

Hope it helps!

Answer 3

Best Solution:

jsonObjectRequest.setRetryPolicy(new DefaultRetryPolicy(0, 
     DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

Worked for me.

Answer 4

Add the following values to your Request object:

request.setRetryPolicy(new DefaultRetryPolicy(
    DefaultRetryPolicy.DEFAULT_TIMEOUT_MS * 2,
    DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
    DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

Here: request is your object of JsonObjectRequest. Change the value of multiplicator according to the DEFAULT TIMEOUT VALUE in DefaultRetryPolicy class in Volley.

You can also set the first argument to 0, like below:

request.setRetryPolicy(new DefaultRetryPolicy(
    0,
    DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
    DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

Answer 5

I found the solution for the double post, I just set the timeout to 0.

Answer 6

I found the solution for the multi post bug.

Change the RetryPolicy. I set the timeout value to 50000ms, worked fine Like this:

  request.setRetryPolicy(
                new DefaultRetryPolicy(
                        500000,
                        DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                        DefaultRetryPolicy.DEFAULT_BACKOFF_MULT
                )
        );
