ERROR Volley Library com.android.volley.ParseError: org.json.JSONException:

问题

I try to do a PUT request using Volley Library. I already did get request and put request usin g Override methode getParam(), but for this request i need to send a jsonOjbect that i created before.

But in the response i have :

08-25 09:44:34.638: I/ViewPdf:  SaveDataToProxy ERROR(8512): 
error: com.android.volley.ParseError: org.json.JSONException: Value <br of type 
java.lang.String cannot be converted to JSONObject

So this is my method connection :

public void SaveDataToProxy(JSONObject jsonObject){

    // Tag used to cancel the request
    String tag_json_obj = "json_obj_req";

    String url = Properties.getUrl_proxy() + ":" + Properties.getPort_proxy() +"/api/points/"+this.id_point;
    Log.i("url",url); 

    final ProgressDialog pDialog = new ProgressDialog(this);
    pDialog.setMessage("Loading...");
    pDialog.show(); 

    JsonObjectRequest jsObjRequest = new JsonObjectRequest
    (
            Request.Method.PUT, url, jsonObject, new Response.Listener<JSONObject>()
            {
                @Override
                public void onResponse(JSONObject response)
                {
                        Log.i(TAG + ":  SaveDataToProxy SUCCESS", "response: " + response);
                }

            }, new Response.ErrorListener() 
            {
                @Override
                public void onErrorResponse(VolleyError error) 
                {
                    Log.i(TAG + ":  SaveDataToProxy ERROR", "error: " + error);
                }
             }
    )

    {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError 
        {
            HashMap<String, String> headers = new HashMap<String, String>();
            headers.put("Content-type", "application/json");

            return headers;
        }
    };

    AppController.getInstance().addToRequestQueue(jsObjRequest, tag_json_obj); 
}

and this is the JSONObject.toString() that i send :

    null

    null

This is not your problem this is server side problem, the server dose not return valid json to you. it actually returns you html code, in order to see what exactly it returns just install add on for broswer for example RESTClient for mozilla and send your request to the server by corresponding type(post-get-...) then see server result.
