android:name
The name of the class that implements the activity, a subclass of Activity. The attribute value should be a fully qualified class name (such as, "com.example.project.ExtracurricularActivity").

then since android:name=".view.TaskListListView" has a leading period, so it is interpreted as android:name="com.stackoverflow.android.geotask.view.TaskListListView".
