Answer 1

I know it is late but i hope it can help others

For my case i wanted to open my page messenger bubble if installed of course

So here what worked for me :

messengerButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String messengerUrl ;
                if (isMessengerAppInstalled()) {
                    Toast.makeText(ServiceClient.this, "messenger is installed , open app bubble", Toast.LENGTH_SHORT).show();
                    messengerUrl = "fb-messenger://user/475527699675914/";
                } else {
                    Toast.makeText(ServiceClient.this, "messenger is not installed , open messenger in browser", Toast.LENGTH_SHORT).show();
                    messengerUrl = "https://www.messenger.com/t/475527699675914/";
                }
                Intent messengerIntent = new Intent(Intent.ACTION_VIEW);
                messengerIntent.setData(Uri.parse(messengerUrl));
                startActivity(messengerIntent);


            }
        });

public boolean isMessengerAppInstalled() {
        try {
            getApplicationContext().getPackageManager().getApplicationInfo("com.facebook.orca", 0);
            return true;
        } catch (PackageManager.NameNotFoundException e) {
            return false;
        }
    }
