WebView with push notification url from mainactivity

Question

Send notification of incoming URLs to the page with the main activity of the recipient on the WebView page, and I want to open the URL on this page.

But he did the current project, directing the browser, opening the page in the receiver. I would be grateful if you could help.

JSON data that I send via push:

{
  "alert": "Push bildirimi",
  "badge": "Increment",
  "uri": "http://www.google.com.tr"
}

    @Override
    protected void onPushOpen(Context context, Intent intent) {
        super.onPushOpen(context, intent);
        ParseAnalytics.trackAppOpenedInBackground(intent);

        } else {

        }
        activityIntent.putExtras(intent.getExtras());
