这个错误是你在不经意间导致的，或者是没有很好的去熟悉volley包的api导致的。

public void onRequest(String url){
        if(isIntnetConn){
            StringRequest request = new StringRequest(url, new Response.Listener<String>() {
                @Override
                public void onResponse(String s) {
                    mListener.onSuccess(s);
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError volleyError) {
                    String errorMsg = "";
                    if(volleyError instanceof TimeoutError) {
                        mListener.onError();
                    } else if(volleyError instanceof ServerError) {
                        mListener.onError();
                    } else {
                        mListener.onError();
                        errorMsg = mContext.getResources().getString(R.string.request_error);
                    }
                }
            });
            request.setRetryPolicy(new DefaultRetryPolicy(20 * 1000, 0, 1.0f));//设置超时时间
            mQueue.add(request);
            //mQueue.start();
        }else{
            Toast.makeText(mContext, "当前的网络连接不可用", Toast.LENGTH_SHORT).show();
            mListener.onIntnetDisConn();
        }
    }

只是因为加了下面这句，bug如期而至。

//mQueue.start();

其实，在RequestQueue实例化的时候，就已经有start了。

private RequestQueue mQueue;
private Context mContext;

public HttpServiceUtils(HttpResquestListener listener,Context context){
       mListener = listener;
       mContext = context;
       mQueue  = Volley.newRequestQueue(context);
}

public class Volley {
    private static final String DEFAULT_CACHE_DIR = "volley";

    public Volley() {
    }

    public static RequestQueue newRequestQueue(Context context, HttpStack stack) {
        File cacheDir = new File(context.getCacheDir(), "volley");
        String userAgent = "volley/0";

        try {
            String network = context.getPackageName();
            PackageInfo queue = context.getPackageManager().getPackageInfo(network, 0);
            userAgent = network + "/" + queue.versionCode;
        } catch (NameNotFoundException var6) {
            ;
        }

        if(stack == null) {
            if(VERSION.SDK_INT >= 9) {
                stack = new HurlStack();
            } else {
                stack = new HttpClientStack(AndroidHttpClient.newInstance(userAgent));
            }
        }

        BasicNetwork network1 = new BasicNetwork((HttpStack)stack);
        RequestQueue queue1 = new RequestQueue(new DiskBasedCache(cacheDir), network1);
        queue1.start();
        return queue1;
    }

    public static RequestQueue newRequestQueue(Context context) {
        return newRequestQueue(context, (HttpStack)null);
    }
}

queue1.start(); 已经在实例化RequestQueue的时候，就被调用了。
