While the general idea of the other answers is sound, you should keep in the shared preferences not a boolean, but a timestamp of when was the last time the first run had happened, or the last app version for which it happened.

The reason for this is you'd likely want to have the first run dialog run also whenthe app was upgraded. If you keep only a boolean, on app upgrade, the value will still be true, so there's no way for your code code to know if it should run it again or not.
