What's the "dot" for when registering an Activity
android, android-manifest
Solution
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.
Problem
I'm kind of a noob at programming for the Android OS. I noticed in the books I have been reading that the authors have placed a "dot" in front of the activity name when registering their activities in the manifest. I've looked around the Android developer site and I can't figure out why we need the "dot". Does the "dot" actually server a purpose? Do I need it? I have included an example below. Notice the "dot" before "NewActivity": ``` <activity android:name=".NewActivity"></activity> ```
