    How to add a new activity:

    • Right click in your project
    • New > Class
    • Enter the name of your Activity.
    • In super class field: android.app.Activity

    Also, make sure you clean your project, close Eclipse and launch it again.

    Finally, double check that you included your new activity in your manifest file.
