Toast.makeText(
	this,
	"Some information",
	Toast.LENGTH_SHORT).show();
Toast.makeText(
	this,
	"Some information",
	Toast.LENGTH_LONG).show();

Don’t forget to invoke .show()!

Snackbar

Snackbar is another light-weight notifcation component that supports buttons. Since it can interact with users, it’s more flexible and is often used to replace Toast for information that requires fast response.
