response 302 location to variable in volley

Question

I'm using volley with callback interface. I'm send post request to server and server response 302 status code. How to set location in responsed header to variable string type? Then i want start new activity with full screen webview with this location.

this code in volley classes send requests:

public StringPostRequest(Context context, String url, Map<String, String> params) {
    this.params = params;
    this.url = url;
    mQueue = Volley.newRequestQueue(context, new NukeSSLCerts());
    }

public void getString(final VolleyCallback callback) {
    StringRequest stringRequest = new StringRequest(Request.Method.POST, url ,
            new Response.Listener<String>(){
                @Override
                public void onResponse(String response) {
                    req = response;
                    callback.onSuccess(req);

                }
            }
            ,new Response.ErrorListener(){
                @Override
                public void onErrorResponse(final VolleyError error){
                final int status = error.networkResponse.statusCode;
                // Handle 30x
                if(HttpURLConnection.HTTP_MOVED_PERM == status || status == HttpURLConnection.HTTP_MOVED_TEMP || status == HttpURLConnection.HTTP_SEE_OTHER) {
                    final String location = error.networkResponse.headers.get("Location");
                    callback.onSuccess(location);

                }
            }
    })
    {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            return params;
        }
    };
    mQueue.add(stringRequest);
}
public interface VolleyCallback{
    void onSuccess(String req);
}

In Main activity i'm creating Map for Post Request.

 Map<String,String> params = new HashMap<>();
    params.put("foo", "bar");
    params.put("foo1", "bar1");
    params.put("foo2", "bar2");

    StringPostRequest getRedirectUrl = new StringPostRequest(this,url,params);
    getRedirectUrl .getString(new StringPostRequest.VolleyCallback() {
        @Override
        public void onSuccess(String req) {
            Log.d("reqInMainact", req);
            RedirectUrl[0] = req;
        }
    });
    return RedirectUrl[0];

But Location in response header not write to RedirectUrl[0] (( Help me please

What exactly are you returning `RedirectUrl[0];` to? You can't return from a callback. You do the action **within** the callback — OneCricketeer, May 27 '17 at 19:35

But Location in response header not write to RedirectUrl[0]

I'm sure it did, but you wrote your asynchronous code as if it was synchronous.

Make whatever method that has return RedirectUrl[0]; be void, and try this

StringPostRequest getRedirectUrl = new StringPostRequest(this,url,params);
getRedirectUrl.getString(new StringPostRequest.VolleyCallback() {
    @Override
    public void onSuccess(String req) {
        Log.d("reqInMainact", req);

        Intent i = new Intent(CurrentActivity.this, NewActivity.class);

        i.putExtra("URL",req);
        startActivity(i);
    }
});

Then i want start new activity with full screen webview with this location
