记住用户

Android users get attached to their devices and to applications that they love. One way to make your application lovable is to make it personal. Android devices know who your user is, what services they have access to, and where they store your data. With your user's permission, you can use that information to make your application a richer, more personal experience.

In this class, you will learn multiple techniques for interacting with your user's identity, enabling you to:

• Personalize your app by remembering users by their account name(s)
• Authenticate the user to make sure they are who they say they are
• Gain permission to access the user's online data via services like the Google APIs
• Add a custom account to the user's device to authenticate your own back-end services
