You can also define a super class for all your activities and find the view once in the parent activity  for example AppActivity java   public class AppActivity extends AppCompatActivity        protected View content        Override     protected void onCreate  Nullable Bundle savedInstanceState            super onCreate savedInstanceState           changeLanguage  quot fa quot            content   findViewById android R id content            and your snacks would look like this in every activity in your app  Snackbar make content   quot hello every body quot   Snackbar LENGTH SHORT  show     It is better for performance you have to find the view once for every activity
