NoClassDefFoundError when using Android Volley

问题:

I am trying to make a network request using android volley library:

    StringRequest jsObjRequest = new StringRequest(Request.Method.GET,                 Network.getFullUrl("/Account/Login"),                 new Listener<String>() {                      @Override                     public void onResponse(String response) {                         // TODO Auto-generated method stub                      }                 }, new ErrorListener() {                      @Override                     public void onErrorResponse(VolleyError error) {                         // TODO Auto-generated method stub                      }                 });  Network.getInstance(this).addToRequestQueue(jsObjRequest); 

I have included the library in the build path under Projects. And it compiles fine,

But when I run the app I get the following error:

[EDIT}

I am using latest version of Android SDK

回答1:

To work with Volley we need to define the dependency into the gradle file in Android project's app module:

dependencies {     ...     compile 'com.android.volley:volley:1.1.0' } 

you can see the latest versions of Volley here.
