 Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.setComponent(new ComponentName("com.companyname.Opiniao","android.intent.action.B"));
        intent.putExtra(Intent.EXTRA_TEXT, editTextEmail.getText() + "\n " + editTextPassword.getText());

Please don't post your code in comments, update your question instead. — EvZ, Mar 12 '18 at 18:25
Xamarin.forms just a c# wrapper for Android and Ios, so you need do it on each platform. — Robbit, Mar 13 '18 at 06:05

I've already been able to solve the problem.

In my Android Aplication, i use this code:

    void enviar(){
    // Usa o nome do package que nos queremos encontrar
    boolean isAppInstalled = appInstalledOrNot("com.companyname.Opiniao");

    if(isAppInstalled) {
       Intent intent = new Intent(Intent.ACTION_MAIN);
       intent.setComponent(new ComponentName("com.companyname.Opiniao","android.intent.action.B"));
        intent.putExtra("Dados", editTextEmail.getText() + "\n" + editTextPassword.getText());
        startActivity(intent);


    } else {
        String url = "http://www.google.com";
        Intent i = new Intent(Intent.ACTION_VIEW);
        i.setData(Uri.parse(url));
        startActivity(i);
    }
}

//Procura o package, se tiver instalado, envia um true, se não encontrar devolve um false
private boolean appInstalledOrNot(String uri) {
    PackageManager pm = getPackageManager();
    try {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

in my xamarin.forms, in android mainActivity, i put this:

        async void Receber()
    {
        text = Intent.GetStringExtra("Dados");
        string dados = "Dados";
        bool result;
        result = await dados.WriteTextAllAsync(text);
     }
