When we download an app, many times when starting it it presents a screen (or several) of instructions for using the app itself?! I would like to know how to do that. If they can't put some code or tutorial address, at least the correct name so you can search!
This presentation is called
User Onboarding or
App Intro . I recommend using the AppIntro library, it already follows all aspects for a great introduction to your application.
You can find an example through this application on the
Play Store .
