Use a leading :. Activity names are *very* different that affinities. Activity (and service, receiver) names are within the namespace of only that package. That is, the official name of an Activity is a ComponentName which is both a package name and the class name. Thus two applications can have activities with the same class name and will not conflict in any way.
Task affinities (and permissions, and processes, and shared user IDs, and actions, etc etc) are NOT qualified by the app package name. They are a single string, much must be globally unique. Just adding a ".foo" does not make it unique because another app could have a package name that is a shorter or longer version of your own and also come up with the same name. So for affinities and processes, you can use a ":" prefix in the name to append it to your own package name and create a name that is guaranteed unique for your package.
