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

Volley request policy only one time request to avoid duplicate post

I tried this solution, but does not working

//...........solution 01
jsonObjectRequest.retryPolicy = DefaultRetryPolicy(
120000, 
0,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT)


or

//...........solution 02
jsonObjectRequest.retryPolicy = DefaultRetryPolicy(
0, 
-1,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT)


MySingleton.getInstance(this).addToRequestQueue(jsonObjectRequest)
