import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button openWhatsAppGroupButton = findViewById(R.id.open_whatsapp_group_button);
        openWhatsAppGroupButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                openWhatsAppGroup("https://chat.whatsapp.com/your-group-id");
            }
        });
    }

    private void openWhatsAppGroup(String url) {
        try {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setData(Uri.parse(url));
            startActivity(intent);
        } catch (Exception e) {
            // Handle the case where WhatsApp is not installed or the URL is invalid
            e.printStackTrace();
        }
    }
}
