Question

I using API for login, if login success it return code 200 with respone. and if incorrect email or password will return code 401 with json object contain errors the problem is that I want to get the network response even the request code not equal 200 like the image

but volley throw exception BasicNetwork.performRequest: Unexpected response code 401

here is my code

public interface OnResponse{
    void onResponse(JSONObject response) throws Exception;
    void onErrorResponse(VolleyError volleyError);
}//OnResponse



public static void newRequest(Context context, String url, final Map<String, String>params, final OnResponse onResponse){
    // - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    // - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

    RequestQueue queue = Volley.newRequestQueue(context);
    //
    //onErrorResponse()
    //onResponse()
    StringRequest stringRequest = new StringRequest(Request.Method.POST, url, response -> {
        // - - - - - - - - - - - - - - - - - - - - -
        try {
            JSONObject object = new JSONObject(response);
            onResponse.onResponse(object);
        } catch (Exception e) {
            Log.e(TAG, "FLAG-1");
            e.printStackTrace();
        }
        // - - - - - - - - - - - - - - - - - - - - -
    }, error -> {
        Log.e(TAG, "FLAG-2");
        onResponse.onErrorResponse(error);
    }){
        @Override
        protected VolleyError parseNetworkError(VolleyError volleyError) {
            volleyError.printStackTrace();
            Log.e("zxc", volleyError.getMessage()+"");
            Log.e("zxc", volleyError.getLocalizedMessage()+"");
            return super.parseNetworkError(volleyError);
        }
    };
    //
    stringRequest.setParams(params);
    stringRequest.setShouldCache(false);
    queue.add(stringRequest);
    // - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    // - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
}//newRequest()`

VolleyError has the networkResponse attribute, it contains the response.

This is an example: String response = new String(error.networkResponse.data);
