Android volley sending data twice

Question

I am using Volley Network Library in my application.

The Issue is that it is sending data more than once when network connection is slow.

Answer 1

No need to use connection.setChunkedStreamingMode(0); to avoid volley sending data twice bug. you need to set retry policy for current request :

JsonObjectRequest jsonObjReq = new JsonObjectRequest(...);
jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(
                       0,
                       DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                       DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
