When creating new android project, getting error "Activity Name must be specified"

Question

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.

normally you need not specify the hirarchial parent whic IDE are you using and which version — Athul Harikumar, Aug 23 '12 at 05:52
I'm using Eclipse Indigo Java EE IDE, version : 1.4.2.20120213-0813 — Nitin, Aug 23 '12 at 05:56
try updating to juno -- i have used indigo earlier but never experienced a similar problem — Athul Harikumar, Aug 23 '12 at 05:58
Okay. I'll do that. But isn't there any way to remove this error. I was using it before but wasn't getting this error. But suddenly it appears for some unknown reason. — Nitin, Aug 23 '12 at 06:00
tried restarting eclipse? and try some other activity names,package name etc — Athul Harikumar, Aug 23 '12 at 06:02
probably some problem with the IDE just try installing the new version should help at times eclipse behaves like hell — Athul Harikumar, Aug 23 '12 at 06:05

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

This is the feature of action bar. I think that the hierarchical parent activity is launched when the user click on the back button of Action Bar. I give the name of launcher activity here and it works fine... As for launcher activity, there is no Hierarchical parent. :)

For me, it requires parent activity for Launcher activity too. – Nitin Aug 25 '12 at 14:30
