Contact Boot Whatsapp android studio

Question

People want to integrate my app with a support button when clicking it will open the Whatsapp through the url and open a Whatsapp chat with a specific support contact.

XML:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".action_suporte_whatsapp">
    <WebView
        android:id="@+id/action_suporte_whatsapp"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerHorizontal="true" />
</androidx.constraintlayout.widget.ConstraintLayout>

Java code:

package com.gennissi.gpstracking;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.MenuItem;

import androidx.appcompat.app.AppCompatActivity;


public class action_suporte_whatsapp extends AppCompatActivity {

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {

            //codigo aqui
            case R.id.action_suporte_whatsapp:
                String url = "https://api.whatsapp.com/send?phone=" + getString(R.string.about_contact_what) + "&text=Solicito%20Suporte%20Aplicativo%20Ibi-System";
                Intent intentSuporte = new Intent(Intent.ACTION_VIEW);
                intentSuporte.setData(Uri.parse(url));
                startActivity(intentSuporte);
                return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

Could someone please help me?
