Refresh webview when user open wifi and back to app

I am loading url in webview, but if wifi is off I am opening WIFI setting.

Now I want when user turn on wifi and come back webview should refresh it self to load url again.

And is there a way to refresh it continuously after 5 seconds only if webpage is not loaded due to any reason.

You can check in the onResume() method if the user has returned back with wifi on and then call his method 

@Override
    public void onResume() {
        super.onResume();
        if(connected){
            webview.loadUrl("your url");
        }
    }

For refreshing it every 5 sec you can use timer 

Handler ha=new Handler();
ha.postDelayed(new Runnable() {
    @Override
    public void run() {
        webview.loadUrl("your url");
        ha.postDelayed(this, 5000);
    }
}, 5000);

I have just written connected in the if condition.You will have to use the way you are checking the connectivity.

wv.setWebViewClient(new WebViewClient() {
    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            super.onReceivedError(view, errorCode, description, failingUrl);
    }
 });

You can keep a boolean flag to check if the url loaded with error and change its value in onREceived error. and load new url only if it had error the previous time.
