Android Webview redirecting after x seconds

Question

So i'm trying to redirect from a webview to another activity after X seconds. The problem is that the new activity is launched two times for some reason..

any solutions? Sample code below.

myWebView.setWebViewClient(new WebViewClient() {

        public boolean shouldOverrideUrlLoading(WebView view, String url){

            final Timer timer =  new Timer();
            timer.schedule(new TimerTask() {
                @Override
                public void run() {
                    Intent intent = new Intent(myContext, RegistrerActivity.class);
                    startActivity(intent);
                    timer.cancel();
                }
            }, 5000);

            return false;
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);

              //Code for response 

            }
