What’s the “dot” for when registering an Activity

by

As you have noticed the point is not necessary but it basically means: the activity class lives in the same package of the app. So, if your app package is: com.my.package then:

  • .YourActivity means that your class is inside com.my.package.
  • YourActivity means that your class is inside com.my.package (same as above).
  • .activities.YourActivity means that your class is inside com.my.package.activitites.
  • You can even do something like: com.my.package.activities.YourActivity which is useful when you want to have different versions of your app and use Ant to change the references to the package automatically.
