Is there a way to run a specific screen (such as ID) the first time the application is opened? And every time I launch an update in google play, people who already have the app installed and reopen after the update, will the idle screen be displayed again? is there a way to differentiate those who download to those who receive an update?

Use SharedPreferences to save the app version.

In the main activity, in the oncreate() method, obtain this information and act accordingly.

String appVer = "versão actual da sua app";
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
String appVer = preferences.getString("lastAppVer","");

if(lastAppVer == ""){
    // A aplicação foi instalada pela primeira vez
    // Exibir tela
}
else if(lastAppVer != appVer){
    // A aplicação foi actualizada
    // Exibir tela
}

In the screen activity to be displayed only once save the version of your app in SharedPreferences

String appVer = "versão actual da sua app";
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
preferences.edit.putString("lastAppVer",appVer).apply();
