anonymous class derived from ErrorListener must either be declared abstract or implement abstract method onErrorResponse(VolleyError error) in ErrorListener

 JSONObject jsonParams = new JSONObject(params);
        final JsonObjectRequest jsObjRequest = new JsonObjectRequest(context, Request.Method.POST, SERVER_URL, jsonParams, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                Log.d("deletePost", "response: " + response);
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.e("deletePost", "error: " + error);
            }
        });

        VolleySingleton.getInstance(context).addToRequestQueue(jsObjRequest);

This is the error I'm getting from Androdi Studio, I can compile and run it without a problem:
anonymous class derived from ErrorListener must either be declared abstract or implement abstract method onErrorResponse(VolleyError error) in ErrorListener

Do you have another module bringing in a Volley dependency by any chance?

Hi .. I'm having the same issue and yea I have another dependency for Volley. In my build.gradle I got :

compile 'com.android.volley:volley:1.0.0'
compile 'dev.dworks.libs:volleyplus:+'

The fact is I can't use only the first one since I need the SimpleMultiPartRequest class for uploading a video file. At the same time I can't use only the second one since I 'm using the basic Volley JsonObjectRequest for basic http requests when logging the user ...

Any clue on how to workout this issue ??

@Saatch me too getting this issue. any workaround ?

[qadir227]

@Saatch just remove
compile 'com.android.volley:volley:1.0.0' from your dependence and sync again.
It seems VolleyPlus has all the functionality on Volley:1.0.0 library (as name suggests)

This should be mentioned in Docs/Read.me file

@qadir227 Yea I figured that out recently... I tried to use Volleyplus only for multipart video uploading requests but then I changed all my other normal volley requests to Volleyplus since they re conflicting each other and removed the dependency ... it solved the problem
