Android make a first time use screen [duplicate]

Question

I want to implement a screen that appears when the user uses the app for the first time, like google does. Is there a special element to use? What would be the best method to check if the user opened the app for the first time?

Take a look into SharedPreferences. It's pretty simple.

    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);

    boolean firstOpened = preferences.getBoolean("first_opened", true);

    if(firstOpenened) {

         showWelcomeScreen();

         SharedPreferences.Editor editor = preferences.edit();
         editor.putBoolean("first_opened", false);
         editor.apply();
    }
