How to display a one time welcome screen?

Question

In my android app, I need to design a Welcome Screen which will be shown to the user only once after the app is installed and opened. The app in question is a database drive

Answer 1

Save a flag in the Preferences when you start up the application, after you've done the welcome screen stuff. Check for this flag before you show the welcome screen. If the flag is present (in other words, if it's not the first time), don't show it.
