To add the Facebook, Twitter etc. share options, the user just needs to have those applications installed. It’s up to other applications what type of Intents they will tell the system they can handle.
Then a basic ACTION_SEND intent will get picked up.
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT,
"Hey check out my app at: https://play.google.com/store/apps/details?id=" + BuildConfig.APPLICATION_ID);
sendIntent.setType("text/plain");
startActivity(sendIntent);
