Open calendar from a link

I seem to have found my own answer. Unfortunately I do not know if I can answer it, but if I can not, I ask the moderators to correct and instruct me so I can understand better.

Well, in iOS we have the webcal, as I said earlier. Mounting links like this:

<a href="webcal://192.168.1.102/scripts/apptest/teste.ics">Agendar</a>

iOS opens the event right

To solve this problem, in the shouldOverrideUrlLoading of my webview, I check if the URL has the webcal, and open a new intent for the calendar, so I drop the ICS and set up a calendar. I know there are better ways to parse in ICS, but follow the code I used

Anyway, I now have the same HTML working for both devices

// Verifica se começa com o protocolo de calendario (webcal para manter padrão com ios)
        if(url.startsWith("webcal")) {

            if (android.os.Build.VERSION.SDK_INT > 9) {
                StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
                StrictMode.setThreadPolicy(policy);
            }
            try {
                // Cria o link para o ICS
                URL urla = new URL(url.replace("webcal", "http"));

                // Coloca em buffer todo o texto
                BufferedReader in = new BufferedReader(new InputStreamReader(urla.openStream()));
                String str;

                // Inicia o calendario e percorre linha à linha
                Calendar cal = Calendar.getInstance();
                Intent intent = new Intent(Intent.ACTION_EDIT);
                intent.setType("vnd.android.cursor.item/event");
                while ((str = in.readLine()) != null) {
                    /*
                        Verificar de não ter espaços entre o :
                        Não usar Z no final do datetime
                     */

                    // Verifica data de inicio
                    if(str.contains("DTSTART:")) {
                        // Cria o formato da data e da o parse
                        SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd'T'HHmmss");
                        Date date = format.parse(str.replace("DTSTART:", ""));

                        // Adiciona o parametro
                        intent.putExtra(CalendarContract.Events.DTSTART, (date.getTime()));
                    }

                    // Verifica data de fim
                    else if(str.contains("DTEND:")) {
                        // Cria o formato da data e da o parse
                        SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd'T'HHmmss");
                        Date date = format.parse(str.replace("DTEND:", ""));

                        // Adiciona o parametro
                        intent.putExtra(CalendarContract.Events.DTEND, (date.getTime()));
                    }

                    // Verifica o titulo
                    else if(str.contains("SUMMARY:")) {
                        intent.putExtra(CalendarContract.Events.TITLE, str.replace("SUMMARY:", ""));
                    }

                    // Verifica o organizador
                    else if(str.contains("ORGANIZER:")) {
