Volley: passing parameters in a string request

volleyHenry.java

StringRequest loginReq = new StringRequest(Method.GET,
				  URL, new Response.Listener<String>() {
	 
	                    @Override
	                    public void onResponse(String response) {
	                    	respnse=response;
	 
	                    }
	                }, new Response.ErrorListener() {
	 
	                    @Override
	                    public void onErrorResponse(VolleyError error) {
	                    	respnse="-1";
	                    }
	                }){
	 
	            @Override
	            protected Map<String, String> getParams() {
	                Map<String, String> params = new HashMap<String, String>();
	                params.put("type","register");
	                params.put("name",fname+" "+lname);
	                params.put("number",phone);
	                params.put("password",pass);
	                return params;
	            }
	 
	        };

	    PesaBoxApplication.getInstance().addToRequestQueue(loginReq, tag_signupReq);
	   
		return respnse;
	

Hi, String object was helpful. I cant get volley to pick up parameters from getParams.
