VolleyPlus : NetworkDispatcher.run: Unhandled exception java.lang.NullPointerException

Question

I am trying to run below code:

Map requestMap = new HashMap<>();
Long unixTime = System.currentTimeMillis() / LONG_1000;
requestM         


        

Answer 1

I traced the stacktrace and I believe that the root cause is response.headers is null in the method parseNetworkResponse for some reason. I would suggest the following to confirm this.

1. Create a class that extends StringRequest

2. In this class override the 'parseNetworkResponse()`. It should look as follows:

      protected Response parseNetworkResponse(NetworkResponse response) {
             Log.d("Response Header = " + response.headers);
             super.parseNetworkResponse(response);
      }
   

3. Use this class instead of StringRequest.

Once done, see if the headers is null or not. That should narrow down the problem. By the way, which version of Volley are you using. I never encountered such a problem.
