When I’m trying to create a new Android Application Project in the step as shown below getting error “Activity Name must be specified”. Same happens when I try to create a new activity.
I’m a bit confused about Hierarchical parent class.
What is use of it?
Why Eclipse is not allowing me to create activity without specifying it? (It should have been optional)
How can I create an Activity without specifying Hierarchical parent?
Thank You very much.

In Eclipse Go to Window==>preferences=>Install/update then click uninstall or update =>Click on Installed Software and update your Android development tool.
