what is the difference between 

@android:id/hello

and

@id/hello

I ask this, cause apparently we MUST use @android:id/list in the Class when we want to extend ListActivity.

  • You don't HAVE to use "@android:id/list". It's recommended and convention, but not 100% necessary. I was "forced" (more like curious) to implement a ListView without the default Android ID when a partner of mine messed with the code in such a significant way that to rollback the changes would have been worse than going along with it. `` – Jon Jun 06 '11 at 13:24

@android:id/hello is the default ID as set by Android (except that I don't think they have a hello set).

@id/hello would be an ID set specific to your application.

The @android:* identifiers refer to pre-defined identifiers in the SDK. Those are the only identifiers known to the framework (like ListActivity). Identifiers like @id/list refer to your app's resources.
