Android display a screen only the first time you open the application

Question

Is there a way to run a specific screen (such as identification) the first time the application opens? And every time I launch an update on google play, people who already have the app installed and open again after the update, will the ID screen appear again? there is a way to differentiate those who download to those who receive an update?

Use the Sharedpreferences to save the app version.

In the main activity, in the method oncreate(), obtain that 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
}

On the screen activity to be displayed only once save your app version to Sharedpreferences

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