Switching from the PreferenceScreen to DialogPreference

Question

My application has a settings menu, which is actually a PreferenceActivity. When it is created, if no boolean is given, I want to go to DialogPreference, which sets this.

I tried to do this with the intention, but the application power closed with this msg error:

E / AndroidRuntime (239): android.content.ActivityNotFoundException: Could not find an explicit activity class {Com.xxxx / com.xxxx.xxxxPreference}; Have you declared this activity in your AndroidManifest.xml?

How should I do it? Can I add that DialogPreference for the manifest?
