Action send facebook only

Question

How can I do Action.SEND with Intent to show only facebook app(or to open it at once)?

I did it for all app witg Action.SEND:

   Intent sendIntent = new Intent();
        sendIntent.setAction(Intent.ACTION_SEND);
        sendIntent.putExtra(Intent.EXTRA_TEXT, "Test text");
        sendIntent.setType("text/plain");
        startActivity(sendIntent);
